Application service platform system is developed based on following hierarchical structure, and on proxy server, proxy server, infrastructure service and the load running application on application server cluster is all developed based on following hierarchical structure specifically:
Exploitation basic framework class libraries (Framework): basic framework class libraries provides basic Core Feature and the expansion interface for customizing in specific transactions field; In basic framework class libraries, define and realize multiple application component AppBean type of foundation, and in basic framework class libraries predefine the realization of application context interface and basic application context type, so that basic Core Feature to be provided; Wherein application corresponding to different AppBean type of foundations, for the processing of dissimilar signaling; The expansion interface that basic framework class libraries provides is specifically used for the new AppBean type of foundation expanded in business framework class libraries BizLibrary and new application context.
According to traffic performance, on the basis of basic framework class libraries, be developed as the business framework class libraries (Biz Library) of business customizing.Business framework class libraries also provides the expansion interface of traffic aided, for expanding new application;
Based on basic framework class libraries and business framework class libraries, exploitation realizes application, infrastructure service and the proxy server of business demand.
Application-dependent, in Framework and Biz Library, realizes business demand.
Infrastructure service depends on Framework and Biz Library, and infrastructure service is provided.
Proxy server depends on Framework and Biz Library, realizes route and loading functional based on business.
In embodiments of the present invention, provide the application and development pattern based on application component (AppBean).Here the granularity that defines minimum exploitation and load is AppBean, and an AppBean is defined as the application program that realizes a small granularity function.
Generally application definition is arrived to signaling rank; be defined into the concrete manifestation form of application of signaling rank according to the difference of business; can have multiple, such as being a specific Http request (as GET/default.do), or a specific up note (FROM:13800138000; TO:10658000032; TEXT:HELLO), or a specific SIP instruction, or a RPC instruction (method is not an interface) etc.
In the embodiment of the present invention, process the application of one or more of instructions, be defined as AppBean, the least unit that application can develop and field is AppBean, can be for a signaling or many signalings exploitation AppBean, and be deployed in plateform system, accept user's request, request may be from user's client software, browser, internal reference, or outside signaling is called.
In the embodiment of the present invention, based on Java, realize certain applications, AppBean is described to an interface (interface), and all specific AppBean can derive from from this interface, in order to realize specific method, such as mechanism, configuration initialization, service loading and service unloading etc. are installed certainly.
AppBean is an abstraction interface, but during application and development, must derive from from the AppBean type of foundation (BaseAppBeanTypes) for specific signaling Treatment Design.
In embodiments of the present invention, the AppBean type of foundation of having realized comprises: process the JobAppBean of the HttpAppBean of HTTP request, the RemoteAppBean that processes RPC request and processing timed task etc.
Each specific AppBean type of foundation can be processed the signaling of particular form, and application developer need to select suitable AppBean type of foundation to go to realize the application of oneself.AppBean type of foundation is not limited to above-mentioned several, can expand the BaseAppBeanType of particular type, and realize the Proxy of particular type processing in the aspect of Biz Library.
About application context (being called AppContext)
In the present invention, not only development mode is split as towards independent signaling, and signaling and application context are bound together, application context is called AppContext.In application service platform system of the present invention, application service context (AppContext) is the key of application call and resource location.Here application call comprises that proxy server calls application service, and in application service, calls other application service, and these two kinds of application all need AppContext to come the location of realize target application service.
AppContext can understand like this: the place environment identity of a current application operation of AppContext binding, such as active user, do like this, developer is based on AppContext(active user in the exploitation moment) develop, access resources (database, file, buffer memory) all must be by current AppContext, developer can be without management database like this, file, the fractionation problem of buffer memory etc., even user data across problem in computer rooms, only close and develop based on active user, simplified greatly development mode, system deployment architecture and development process are kept apart, realize efficient, PaaS platform easily.
AppContext forms and is divided into two parts from data, and AppContext is serializability and unserializing:
(1) generic resource identifier URI(Context Uri): be string format, comprise user's index information, be responsible for follow-up location, as id:230302023; Session:13910000001.
(2) additional data (ContextData): be the strongly-typed data structure that predefine is good, can comprise multiple fields; It comprises the attribute information of this application; The attribute information of application comprises: session parameter, authorization message etc.;
In some occasion, additional data can produce and be applied in the long Proxy server scene connecting by Proxy.
Support getNamedValue (String fieldName) method, can get the data of a specific fields name, the method is used to gray scale issue occasion (seeing below literary composition).
AppContext is abstract base class, in Framework predefine below AppContext subclass:
NullContext: predefined empty context, is used in and does not need contextual occasion;
SessionContext: preserve the context of session Id for predefined.
In complicated applications, generally can in Biz Library, expand specific AppContext, such as an IM system, on SIP Proxy, can preserve user's Session, we can expand UserContext so, can receive the upper Session information of preserving of Proxy in the time of so each application processing.
When using application service system platform of the present invention to carry out regarded as output controlling, need some bases that first custom service is relevant, AppContext is exactly one of them.Exemplify a specific embodiment about AppContext below.
For example: use application service platform system of the present invention to open an instant message (IM) system, user in this IM system adopts an integer id to position, can customize according to following mode so the AppContex of this IM system, from AppContext, derive from called after UserContext:
Uri part: " id:230302023 ", represent user's id, so by this user's id, application service position and database memory location that can consumer positioning;
Data part:
-user's logging in network address;-client type etc.;
When having customized user's UserContext, the AppBean operating based on user in all these systems can use the ﹤ C ﹥ parameter of UserContext as AppBean, as:
-obtain subscriber data;-subscriber data is set;-obtain buddy list etc.;
In addition, in application service platform system of the present invention, except providing the AppContext based on unique user, type of service based on group is also provided, and the application service of exploitation based on group, also needs the AppContext of customization based on group, IM system is used an integer to be used for identifying group, from AppContext, derive from, called after GroupContext, the structure of GroupContext is as follows:
Uri part: " group:123123 ", the sign id of group, expression user's id, by the id of this group, we can locate the application service position of group, with database memory location so;
Data part:
The session parameter of-group; The mandate of-group etc.;
When after the GroupContext having customized based on group, all AppBean that operate based on group in this system can use the ﹤ C ﹥ parameter of GroupContext as AppBean, as:
-group name is set;-renewal group authority;-obtain group deferred information etc.
Metadata mark (Annotations) information of application
In invention, while developing an application AppBean and expansion AppBean, can be by the mode of loading of Java metadata mark (Annotation) mark application, the data such as operational mode, after this data compilation, can load in the runtime, or from the binary system bag compiling, data be extracted from reflection.
In an embodiment of the present invention, as described below, the AppBean of expansion can define own specific Annotation to some predefined Annotations.
1. name and the systematic name of@AppName(application)
Name and the systematic name of statement AppBean;
–@AppName(category="Core",name="GetUserInfo")；
Here@xxx is the mark of Java language to program metadata.
The Category:name overall situation is unique;
Category can be for the classification of AppBean;
– facilitates O&M personnel to be configured and classifies;
–, in a Category, if allow an AppBean to be accessed by the AppBean in other Category, must become this AppBean statement openly, or friendly;
@Public (): allow all AppBean access;
@Friendlly (" Core "): only allow to specify Category access;
@Friendlly (" Core:AddBuddy "): only allow to specify application access.
2. the state information of@Stateful(application)
When statement, an AppBean has state, and this AppBean can be kept at state in the machine internal memory;
The application that does not mark@Stateful is all considered as stateless application, bans use of the machine internal memory to carry out the preservation of state;
If the Stateful parameter the same (" Presence ") of the multiple AppBean statements in a Category, these several AppBean start in a process, and do not allow heat separately to upgrade;
Can lost condition in the time of being applied in heat and upgrading of@Stateful, so go to replace by memcache mode as far as possible, suggestion is only in the very high field startup of some performance requirement;
When certain AppBean is declared as Stateful, for the access of this AppBean, can adopt the mode of the consistency Hash of the AppContext binding of this AppBean to carry out route.
3.@HttpPrefix
HttpPrefix(HTTP prefix, only for HttpAppBean)
The Http request scope of processing for marking a HttpAppBean;
As :@HttpPrefix ("/login.do ");
-represent that this HttpAppBean processes take login.do as initial http request.
Message Name(event title, only for MessageAppBean)
For marking the title of a MessageAppBean;
As :@Message Name
4.@ContextLoader(load application Service context information)
Be used for marking an AppBean and how load AppContext
As :@ContextLoader (name=" CookieParser ")
-represent to remove to process Context by the program of CookieParser by name;
-CookieParser program is built in the middle of Proxy, by the Cookie field of processing in Http Request, removes to load user related information.
In an embodiment of the present invention, some predefined Annotations are not limited to as above several, can be according to other mark of practical business increase in demand.
Basis AppBean type (AppBeanBaseType)
In Framework, realize the step of an AppBeanBaseType and describe as follows:
An AppBeanBaseType comprises following assembly and characteristic:
AppBeanBaseType is an abstract base class
AppBeanBaseType must add mark@AppBeanBaseType, could be recognized by AppLoader like this
In AppBean, do not have the method for definition process business, but the abstract method of processing business must be provided in AppBeanBaseType, offer application subclass and go to realize
In the application moment, AppBeanBaseType is single-piece, can import whole required parameters of this service operation in Business Processing abstract method into, and with the affairs abstract class of answer method, we are referred to as AppTx
AppTx generally can be bundled on an AppContext
Must realize corresponding AppHost class, the actual method for processing business that triggers AppBean of AppHost class meeting, AppHost can derive from together with AppBeanBaseType
Generally need to realize the AppBeanRouteManager that is responsible for this request of distribution and the Proxy(independent agency service of processing application)
In Framework, realized the AppBeanBaseType on several bases, but applying spendable AppBean is not limited to several types below, can also on Biz Library level, expand.
1.HttpAppBean(HTML (Hypertext Markup Language) application component)
HttpAppBean is for the treatment of a specific Http request, and Http request may come from the direct request from subscription client browser or program, and request meeting is forwarded in application process by 7 layers of load of intelligence of Http Proxy.Http request also may derive from the request of other servers.
HttpAppBean<C extends AppContext> is a general type class, and wherein general shape parameter is explained as follows:
Context <C>: the context of particular type
Context source: from where obtaining context ﹤ C ﹥;
URL prefix: the URL prefix (URL prefix is processed by@HttpPrefix metadata mark) that this application is processed
HttpAppBean indicates own handled request UrlPrefix(prefix by mark), for example, develop a step for the simplest HttpAppBean roughly as follows:
1. from the base class of HttpAppBean, derive from
@HttpPrefix(“/Hello”)
@AppName(category=”example”name=”hello”)
class?HelloWorldAppBean?extends?HttpAppBean<NullContext>()
2. specifying context type <C>, is NullContext, does not need context;
3. by@HttpPrefix, mark, represent for the treatment of the address that is dealt into@HttpPrefix mark
Request;
4. by AppName, mark, represent that the catalogue of this application is example, name is called hello;
5. realize process () method, process () method is the abstract method defining in HttpAppBean,
Read HttpRequest, after processing, return to HttpResponse to client.
For example: developing a flow process for the application of user's unified login authentication is:
1. from the base class of HttpAppBean, derive from;
2. specifying application service context type ﹤ C ﹥ is SessionContext;
3. specify Context source for the ssic field in cookie;
4. realize process method, read HttpRequest, after processing, return
HttpResponse is to client.
2.RemoteAppBean(far call application component)
RemoteAppBean derives from from AppBean, is used for processing a specific Rpc request, and Rpc request may derive from following several scene
Deriving from calling of other AppBean, may be to carry out arbitrarily Source Type;
Derive from its proxy;
Deriving from other external service calls.
RemoteAppBean is a general type class, and wherein general shape parameter is explained as follows:
<A>: required parameter, strongly-typed definition, serializability;
<R>: reply parameter, strongly-typed definition, serializability;
<C>: the application context of particular type.
Realize a RemoteAppBean definite following type must be provided, the step of for example developing the RemoteAppBean that a processing obtains subscriber data is as follows:
1. from the base class of RemoteAppBean, derive from
@AppName(category=”example”,name=”GetUserInfo”)
class?GetUserInfo?extends?RemoteAppBean<GetOption,UserInfo,
NullContext>
2. definition required parameter type <A> is GetOption, and GetOption is serializability class, preserves id and the option parameter of obtaining user;
3. defining and replying parameter type <R> is UserInfo, and UserInfo is serializability class, preserves user profile;
4. defining context <C> is NullContext, does not need context in present case;
5. after inheriting, realize process () method for the treatment of service logic, inherit load () method and use with just
Beginningization, inherits the unloading of unload () method, inherits setup () method and realizes from installing.
The application context (AppContext) of the particular type that this RemoteAppBean states when realizing must be provided when calling a RemoteAppBean.
An application meeting of obtaining user profile is stated as follows:
1. from RemoteAppBean ﹤ GetOption, UserInfo, derives from UserContext ﹥;
A. required parameter ﹤ A ﹥ is GetOption, for obtaining some option parameter of user
B. replying parameter ﹤ R ﹥ is UserInfo, is the set of user profile
C. application context ﹤ C ﹥ is UserContext, is the user profile of current context, and UserContext is for identifying user ID
2. realize process method and process service logic
3.JobAppBean(task application assembly)
JobAppBean derives from from AppBean, is used for processing a timed task, and can in the overall situation, guarantee that timed task monopolizes operation in certain resource.
The step that realizes a JobAppBean is as follows
1. from the base class of JobAppBean, derive from
@JobSchedule(cron=”*/5****”)
@JobResource(resource=”USERDB”,parallel=true)
@AppName(category=”example”,name=”GetUserInfo”)
class?GetUserJobApp?extends?JobAppBean
2. the running time of definition Job, wherein the running time of Job is according to explaining in Corn expression formula
Time operation
3. the resource that definition Job will monopolize, asks for an interview next joint about the definition of resource, after binding resource,
JobAppBean in plateform system will can not rerun when for this resource.
Resource access location based on AppContext
In the present invention, define and realize after an application with certain business function, this application certainly will will be accessed various resources, as database, file server, memory object buffer server or other services providing etc.Application service platform system in the present invention is large-scale distributed system, so these resources are not single-point services, namely the database of same type may exist the example of multiple longitudinal fractionations (Sharding).The resource binding that in the present invention, an application can be accessed is on its application context AppContext.
Such as, stating an application of obtaining user profile, GetUserInfoApp by name, reads customer data base (UserDB) at the realization link of application, and result is returned.There are multiple examples of longitudinally splitting of being undertaken carrying out after delivery by user id in UserDB wherein.
Detailed process is as follows so:
1. proxy server Http Proxy receives the Http request that comes from client;
The URL that 2.Http Proxy asks by Http judges the application of this request correspondence; Be specially Http Proxy by the application configuration information list on access central server, find the@HttpPrefix application configuration information list items consistent with the URL of Http request in metadata mark Annotations field, the application that this list item is corresponding is this Http and asks corresponding application;
3.Http Proxy is the request of GetUserInfoApp by this request of step 2 identification, and needs UserContext as context parameters;
4.Http Prorxy is according to the@ContextLoader in the Annotations field in application configuration information list item, and the relevant information of extracting in Http request message creates UserContext;
After 5.Http Proxy has added UserContext data in the Http request from client, Http request is forwarded to the application server at GetUserInfoApp place; Here by the list of inquiry application operation information, obtain the address of service of GetUserInfoAPP.
6. the application process of the operation GetUserInfoApp on application server receives Http request, extracts UserContext, and gives GetUserInfoApp and process;
7.GetUserInfoApp reads UserDB, when reading UserDB, by the id information in UserContext, carries out the location of UserDB;
8.GetUserInfoApp organizes returned packet, and returns to Http Proxy;
9.Http Proxy returns to client by returned packet.
In the step 7 of said process, by resource (Resource) table, position.Resource table is in one embodiment of the invention as shown in table 1:
Table 1
Can, by realizing different mapping function (Locator), realize the different locate modes for different resource.For example, in upper example, the concrete configuration of resource table is as shown in table 2:
Table 2
While using id:1001 location UserDB in step 7, ModDatabaseLocator can take out 1001, and by 1001 except 5, remainder number is 1, returns to the database instance of UserDB.1 by name.
Again for example:
Develop an instant message (being abbreviated as IM) system, user in this IM system adopts the id of an integer to position, and scheme customizes the AppContext of this IM system so as follows, from AppContext, derives from, called after UserContext
– Uri part: " Id:230302023 ", represent user's id, so by this user's id, the application site that we can consumer positioning, with database memory location
– Data part:
User's logging in network address,
Client type
Deng
As the UserContext having customized based on user, the AppBean operating based on user in all these systems can use the <C> parameter of UserContext as AppBean
As: obtain subscriber data, subscriber data is set, obtains buddy list,
But in an IM platform, except the AppContext based on user is provided, also there is the type of service based on group, the application of exploitation based on group, also need the AppContext of customization based on group, IM system is used an integer to be used for identifying group, and GroupContext structure is as follows so
– Uri part: " group:123123 ", the sign id of group, expression user's id, by the id of this group, we can locate the application site of group, with database memory location so
– Data part comprises: the session parameter of group, the mandate of group etc.
When after the GroupContext having customized based on group, the AppBean operating based on group in all these systems can use the <C> parameter of GroupContext as AppBean
As: group name is set, upgrades group authority, obtains group deferred information,
Next introduce application and development mode based on plug-in unit and the pouring-in debud mode of application
In the application and development based on Java of the present invention, based on existing plug-in unit system (Eclipse), generated expansion plugin, this expansion plugin connects development management server and realizes following functions:
Create also management engineering assembly, the upgrade-system of realization based on version;
Create the skeleton code of application;
The generation of realization to RemoteAppBean invoke code, and the Dependency Specification of assisting management;
The pouring-in debugging of realization to application.
The version management of assembly
In native system, in exploitation, need to carry out the dependence of different editions assembly, the mode relying on for the version of base library is as follows, for example:
During exploitation Apps1.0, rely on as Framework-1.0.jar BizLibrary-1.0-jar;
During exploitation Apps2.0, rely on as Framework-1.1.jar BizLibrary-2.0-jar.
Native system addresses this problem like this, and version is defined as follows:
1.0 versions, rely on storehouse and comprise: Framework-1.0.jar; BizLibrary-1.0.jar;
2.0 versions, rely on storehouse and comprise: Framework-1.1.jar; BizLibrary-2.0.jar.
This version information is created by development management person, and each upgraded version all need to increase this configuration information newly in the repository of development management server.
Dependence configuration during new construction is set up
While creating App engineering, exploitation need to be selected a current version, and when developer selects after version, the step that plug-in unit carries out is as follows:
1. by development management server, obtain the information of the bag of dependence;
2. obtain the bag of particular version;
3. dependence is joined in current App engineering-environment;
4. version number is write (this version also can follow-uply have influence on program and reach the standard grade, and gray scale issue) in META-INF/AppBean.properties version
The dependence configuration upgrading of old engineering
When we need carry out the upgrading of old application according to the base library of new issue, such as, when base library upgrades to 2.0 versions, our step during by application upgrade to 2.0 version of 1.0 versions is as follows:
1. developer selects current version to 2.0;
2. plug-in unit reads the dependence library information of 2.0 versions to edition management system;
3. the dependence plug-in unit of plug-in download development management system configuration;
4. replace local dependence;
5. upgrade successfully.
The generation of the invoke code to RemoteAppBean
RemoteAppBean is the key concept of realizing application exchanging visit and application level in native system, when having realized RemoteAppBean and after AppLoader uploads to central server, any one wishes that the application of this RemoteAppBean of access need to generate the proxy class of calling for this RemoteAppBean.
When the application that need to access RemoteAppBean of exploitation, expansion plugin obtains published all RemoteAppBean from development management server, and its information is shown to developer, and developer selects the RemoteAppBean that will call again; Expansion plugin obtains following information from the reflective information of selected RemoteAppBean: Apply Names and type information; Expansion plugin is according to obtained Information generation request and acknowledgement type entity class; Expansion plugin is according to described request and reply entity type establishment proxy class, and this proxy class is inserted in the described application that need to access RemoteAppBean.
Concrete steps are as follows:
1. developer starts to carry out RemoteAppBean dependence;
2. plug-in unit is accessed development management platform and is received current all disclosed RemoteAppBean, and developer is returned to and be shown to its information;
3. developer selects the RemoteAppBean that will call;
4. plug-in unit, from the reflective information of RemoteAppBean, obtains following information:
A)@AppName: Apply Names;
B) type information, comprising: request, reply, and context type;
5. plug-in unit basis Information generation request above, acknowledgement type entity class, this process is as follows:
A) AppLoader can, by request and acknowledgement type, save as the intermediate data of reflection, preserves in management platform storehouse;
If b) this type is in the middle existence of quoting of this engineering, directly quote such;
C) otherwise plug-in unit according to intermediate data, regenerate the code of request and the class of acknowledgement type;
6. the request of using previous step to obtain, with acknowledgement type, creates proxy class, and proxy class can be used the context type obtaining in step 4;
7. the initialization of proxy class is inserted in the AppBean calling.
Rely on and detect
In large-scale complex platform, the dependence between different services is a problem that is very difficult to management.
In the present invention, show the Dependency Specification creating between application, and detect Dependency Specification in the renewal process of application, with the renewal that determines whether to apply.
When AppLoader loads the App engineering of an Existence dependency, Dependency Specification can be saved as to following data:
Caller;
Callee;
The required parameter type information relying on;
The parameter type information of replying relying on.
For example, when application B relies on application A, system can create Dependency Specification:
Caller: B
Callee: A
The required parameter type information relying on: A.RequestArgs
What rely on replys parameter type information: A.ResponseArgs
Dependence in the renewal process of application detects
B is to A Existence dependency, but when A upgrades to A ', the step that relies on detection is as follows:
1. deployment program is uploaded application A ', and initiate to upgrade instruction;
2. deployment program finds that application program B depends on A, request that at this moment can the dependence to A to A ' and B and reply parameter and contrast, have two kinds possible:
A) request of A ' and reply the request of parameter and A and reply parameter compatibility (equate, or backward compatible), system allows to upgrade, and A and B are labeled as to refresh routine;
B) request of A ' and reply parameter and the request of A and to reply parameter incompatible, system will not allow to upgrade, unless the renewal of B is also submitted in the lump, or first B is rolled off the production line.
Version test specification is estimated
By the description of a upper joint scene, when the application and development of certain version, system can record the more new record of all time points, when system manager determines while reaching the standard grade version, can extract the range of application list that may have influence on after certain time point from certain time point like this.
This list can be carried out automatic test specification judgement, and the step of extraction is as follows:
1. find out all application of upgrading after time point;
2. find out the application that relies on these application;
3. recurrence is found out the application in step 2, until there is no refers to;
4. include all application of finding out in test specification.
Pouring-in debugging
Generally debug an application program and program division need to be deployed to (test environment or production environment) in the middle of actual motion environment, but the application being deployed in test environment is difficult to debugging, and native system has been invented a kind of pouring-in solution can solve the debugging problem of developer for running environment.
Solution is: expansion plugin is applied at local boot; The application of described startup creates and is connected with proxy server, and sends to proxy server the configuration parameter that will debug application; The described configuration parameter that will debug application limits the user in specified scope; Proxy server is receiving after client request message, first described in coupling, to debug the configuration parameter of application, if the match is successful, client request message is sent to the application processing of described startup, and the result that the application of described startup is returned sends to client, if mate unsuccessfully, client-requested is distributed to the application server at corresponding application place.
When the application of described startup is exited, interrupt being connected between proxy server, proxy server is deleted the configuration parameter of this application.
Fig. 2 is the schematic diagram of the pouring-in debug system in the embodiment of the present invention.Referring to Fig. 2, plug-in unit is connected with the proxy server in system shown in Figure 1, has only illustrated proxy server and the application server cluster in system shown in Figure 1 here.
As shown in Figure 2, in the environment of normal operation, proxy server can be directly issued in the request of client, and then proxy server sends specific application server according to application configuration, referring to the description of chapters and sections above.
The step of injecting debugging is as follows:
1. the application meeting starting by plug-in unit creates long connection with the proxy server of particular type (each all will create), and interception request;
2. application sends to proxy server the request of injection, and the configuration parameter of the application of debugging is sent to proxy server, and wherein the configuration parameter of plug-in unit restriction application must comprise grey parameter (namely can only affect the user in fixed range);
3. proxy server can add injection in local routing table;
4. when proxy server listens to after the request from client, can judge whether request meets current injection condition; The request meeting that does not meet injection condition is carried out route according to original logical routing.
5. the request meeting that meets injection condition is connected request is transmitted to the application that plug-in unit starts with the length of proxy server foundation by plug-in unit;
6. application meeting will be converted to request under normal circumstances from the request connecting, and pass to application and process, and will reply to return and send to proxy server, and descending to client by proxy server;
7. after application is exited, can interrupt with being connected of proxy server, at this moment proxy server can remove injecting item automatically.
So just realized the injection debugging of carrying out environment on developing engine.
From above-mentioned, this expansion plugin of the present invention is applied at local boot, the application of described startup creates and is connected with proxy server, and to debug the configuration parameter of application to proxy server transmission, proxy server is receiving after client request message, first described in coupling, to debug the configuration parameter of application, if the match is successful, client request message is sent to the application processing of described startup, and the result that the application of described startup is returned sends to client, if mate unsuccessful, again client-requested is distributed to the technical scheme of the application server at the correspondence application place in cloud computing application service system, can on the developing engine of application, carry out the pouring-in debugging of environment.
The foregoing is only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.All any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., be all included in protection scope of the present invention.
