Description
Technical field
The present invention relates to software dynamic expansion fields, are more particularly to a kind of compile by multilingual cloud and realize system function
The method and system of dynamic interception extension.
Background technique
With the fast development of science and technology, the continuous improvement of social informatization degree, computer application has been penetrated into
The every field of society, competition and diversified customer demand between enterprise, causes enterprise application software system more and more huger
It is big and complicated.Client changes frequently the individual demand of software systems, while requiring the development cycle short, general mark in reality
The product of standardization is difficult to meet the business demand of client's complexity.System development finishes, and has met the needs of users, but works as user
When constantly proposing new requirement, original software architecture can not may be competent at the demand of newly-increased task, need to set again
Meter develops this application system, serious waste manpower and other unnecessary resources.Meet a visitor even if developing again
The application system of the customization demand at family can not guarantee that the demand of user will not change again or have new customer demand simultaneously
It proposes.So if special personalized customization is done in the continuous upgrading of software systems to client, by the quality of software, efficiency,
Management brings serious problems.More codes is added on the basis of original design simultaneously, original code can be by continuous rotten
Erosion, the architecture of system will be also increasingly difficult to safeguard, it is seen that the architecture design at initial stage is to meet the standard of a part
Customer demand is not able to satisfy all demands, if the software systems of enterprise allow this unpredictable variation to start, that is whole
The code of a software systems will not be controlled.
Below by a scene, the variability of customer requirement is illustrated:
Example: in some online recruitment system, logic originally is, is all new addition one when resume enters system
Record thus has a large amount of duplicate resumes and there are (mailbox, mobile phone are different) in systems, is unfavorable for interviewer and checks letter
It goes through；Present client A proposes new demand, and when the information automatic log-on of applicant's resume, system is needed according to applicant
Identification card number, come detect judge this applicant whether before whether there is in systems, and if so, two resumes are believed
Breath is merged and is saved again, if there is no being then added；And the demand of another client B is, when system enters resume
When, judged according to cell-phone number or mailbox, if having existed this resume in system, is no longer added；The demand of client C is, when
This resume is frequently delivered whithin a period of time to be entered system greater than predetermined number of times and meets primary condition set by position, then certainly
It moves and sends an envelope mail to interviewer, show that this applicant has strong registration hope, interviewer should pay close attention；Client D's
Demand is to need to carry out applicant's scoring according to the element in resume when resume enters system, for example 985,211 school adds
10 points, 6 grades of English plus 8 points, 4 grades of English plus 6 points etc., integrated ordered screening operation is carried out convenient for interviewer；The demand of client E
Be need to be selected according to the specific custom rule and specified conditions Automatic sieve of client qualified resume so that automatically into
Enter interview stage or superseded state, if also needing to send short message and mail arrangement interview to interviewer into the interview stage, into
Row prompting etc..
It can be seen that client for the operation expanding demand numerous and complicated of system from the above case, it is different, such as how
Customers as center, fast custom, which is spread, issues the individualized software system of client of being adapted to, for client and enterprise to Guan Chong
It wants.
It in the prior art, is all in corresponding functional module using soft when adding in systems or extending new function
Part developing instrument directly adds code logic, then carries out manual recompility, packing, deployment, this method is for software
Developer's larger workload to some degree, working efficiency is low, and due to being directly to add in existing system module
Add code, error rate is higher, while may destroy the architectural configurations of original system.Although currently passing through certain technology
Factory/IOC/AOP mechanism, solves this problem in that a certain extent, can be directly injected into during system is in differentiation
New code, the architectural configurations without changing original system, but these modes are also present in various limitations and deficiency, pass through
The patented technology retrieved below is explained.
1, patent " a kind of water analysis calculating service system for supporting on-the-flier compiler of 102708452 A of Patent No. CN
System ", disclose following technical characteristic: water analysis algorithmic code user can voluntarily input, then by calling on-the-flier compiler
Server carries out on-the-flier compiler to text codes, generates new dynamic link library or updates already present dynamic link library, and is real
Shi Gengxin water analysis algorithms library carrys out the fixed algorithm of dynamic replacement with this, achievees the purpose that expansion system algorithm, improve flexibility
And opening.There are the deficiencies of the following aspects for the invention: be on-the-flier compiler used in the invention being first Microsoft
CodeDOM ICodeCompiler compiles mode, is utilized in .NET Framework comprising an entitled " code document object
The mechanism of model " (CodeDOM), which allows the developer for the program for writing source code at runtime, according to expression
The single model of presented code is compiled with programming language text generation compilation of source code as a result, it is substantially complete
One flight data recorder, result is success or failure after can only providing compiling, compiling；Secondly code is compiled each time
When, it can all restart another new csc.exe or vbc.exe compilation process, ICodeCompiler except current process
Compiling mode is only the packaging to csc.exe and vbc.exe, this old mode, by test, if in multiple script generations
For code simultaneously when compiling, CPU causes certain pressure, steeply rises CPU usage, in addition restart except current process it is new into

2, patent " the pluggable Web service dynamic call based on DotNet platform of Patent No. CN 101534324A
Method " using on-the-flier compiler generation Client Agent class, it is decided whether to call remote Web services according to configuration file, be held
Row calls the service logic method of remote Web services, the result that method executes finally is returned to software systems, this is in certain journey
The degree of coupling between caller and Web service is reduced on degree, realizing has pluggable property and dynamic call.But it is moved in the invention
State compiling is only applied the service logic for deciding whether to call remote web server with this in client and is generated and calls
The dynamic proxy that remote service is called, remote Web services service logic is fixed, if system needs to extend, it is also necessary to soft
Exploitation, manually compiling, packing, deployment under part developer's line.Secondly, the configuration first read is literary when calling remote Web services
Part, the only message of information and separate unit remote web server whether opened of remote service in this configuration file, if open
Whether configuration decision systems can call remote Web services, and remote web server information determines which platform service is system will call
The Web service of device, configuration here only has a server, rather than has multiple servers, this will can not achieve and patrol business
Volume at the same be deployed on multiple servers, realize that the load balancing of service logic is extending transversely and distributed deployment, thus one
Multi-user, high concurrent request will not be adapted to by determining degree ceiling system；The WSProxy class said in the invention again is basis
Long-range WSDL (Web Services Description Language) description information, generation Client Agent SProxy, and
This proxy class of on-the-flier compiler in memory, that on-the-flier compiler used herein equally uses is also CodeDOM ICodeCompiler
Compiling mode, shortcoming and deficiency are as described above；WebService delivery protocol used in the invention is SOAP (Simple again
Object Access Protocol Simple Object Access Protocol), its internal principle of SOAP is to carry out transmitting data by XML,
Due to XML more it is tediously long parsing it is time-consuming, it is much bigger compared to for binary file, can consume more Internet resources and compared with
More CPU and memory source, therefore a drawback is also become using XML.
3, the patent " one kind is based on bridge architecture cooperation reflection dynamic technique " of 103823658 A of Patent No. CN provides one
Kind based on bridge architecture cooperation reflection dynamic technique, be convenient to program dynamic expansion flexible configuration, it can be achieved that component it is pluggable or even
The flexible expansion of code level changes.Step 6 in this invention: reference dynamic reflective, dynamic mapping is established in statement, from configuration file
Reading value and to this assignment, the class to be radiated is read in configuration file, is abstracted the base class of variation.There are 2 aspects herein
Insufficient: the invention has used reflection technology first, and reflection technology is actually a kind of operation of explanation, inside bottom run mode
Need to do many work: binding procedure, the comparison of metadata character string, parameter verification, type checking, safety check generates a large amount of
Temporary object etc. can cause great burden to CPU and GC Garbage Collector, and very low in operational efficiency and performance.Secondly, dynamic
The service logic of state reflection is relatively-stationary, is to belong to the file of exterior, and these files are to need software development people
Member's exploitation, manually dispose manually, is not real pluggable heat deployment in a sense, is not carried out the flexible of code level yet
Extension.
4, a kind of patent " multi-data source mvc model framework that elasticity is expansible " of 104484182 A of Patent No. CN mentions
For a kind of multi-data source mvc model framework that elasticity is expansible, solve on the interface the same view View in systems, it can be with
Flexible choice calls a variety of different data source business logics simultaneously, and user only needs to increase relevant configuration and data by extension
The problem of existing application dynamic expansion multi-data source and other related services are not easy can be realized in the mapping code of library table.
Its internal principle using be using Spring ioc mode to EB (EntityBean) layer, Service layers (Business Logic),
DAO layers (persistence object additions and deletions, which are looked into, to be changed) and PO (the persistence entity object of the data mapping of Object Relational Database
HibernateORM seamless integration control) is carried out, is realized by configuration file dynamic assembly.There is the following that can change among these
Into the ioc mode of Spring having been used in the invention first, ioc can be added by way of code and configuration, and the invention is
The extension that data source is carried out by way of a large amount of configuration files is very cumbersome, and this is to need manually to be configured,
Additional maintenance cost is caused, coupled relation only a conventional relationship type number library can only obtain data all in configuration file,
Secondly this due to using IOC mode (reflection) that performance issue can be generated, again in Service Business Logic, if necessary
Secondary filter working process is carried out to the data source of taking-up, then needs to develop under boostrap, dispose, configuration.
Comprehensive statement above is it is found that exist in the prior art following disadvantage: (1) extension is complicated: code has direct-coupling
In existing system or by reflection configuration into system, this makes entire expansion process extremely complex cumbersome, and broken reduction
There is the structure of code；(2) reuse of code is low: the code logic newly extended is intended merely to currently developed and is coupled to system
In, it reduce the reuse rates of code；(3) performance is lost: doing extend in systems by reflection or configuration mechanism, will lead to and be
The performance of system declines a rank.(4) when development cycle long low efficiency: extending or adds new demand, developer's line is needed
Under develop again, compile, test, uploading, configuring, being packaged, deployment system, this makes development cycle very long efficiency very low.(5) difficult
To safeguard: the application of system developer and technology is possible to that all iteration has been crossed many times, mutual between code in system
It calls, be mutually coupled also intricate, the people for not quite understanding system dare not act rashly.Summation function is needed to get over system
Come more, team is increasing, and linking up cost, development cost, management cost accordingly can all be multiplied, when system lacks
Fall into when, will also result in problem analysis, orientation problem, repair problem time it is longer；As the increase of size of code is also possible to lead
Cause the vicious circle of " reparation is more, and defect is more "；A small change is with regard to needing to redeploy entire application system in system.
(6) development language limitation: if application system using certain language development, then must also be when demand extends again
This language is extended, and can not attempt new programming language or frame, this is also impossible at present using a technology in reality
Platform or scheme solve all problems.(7) hardware cost is high-leveled and difficult with horizontal extension: all program codes are in the same of server
In one process, horizontal extension difficulty and situation at high cost will lead to, because functions of modules different in system is actually to clothes
The requirement of business device is different, and is had plenty of CPU intensive computer type, is needed the stronger CPU processor of performance, have plenty of needs
Memory I/O intensive type needs to carry out data buffer storage using a large amount of memories, if infrastructure server required by system pressed
Same standard goes to purchase, then hardware cost can be very high.(8) reliability is low: all functions of modules all operate in a process
In, a mistake bug in any one functions of modules, such as RAM leakage/CPU Continued, it will it is possible that do to collapse or
Slow entire process is dragged, to influence the reliability entirely applied.(9) can not distributed deployment support high concurrent: due to can not
Dll or Jar that outside relies on are carried out physical machine with existing system program to efficiently separate, with the continuous upgrading of system
And extension, huge in this way and complicated system, it to stretch and be necessary for the flexible of monoblock type, formula can not be efficiently separated and stretched, system
The core business point often operated required for middle user may only have 30%, and do now by non-core 70% same
Deployment is flexible, cannot reach the maximization intensive use of resource.(10) continuous integrating and delivery are influenced: due to the Pang of operation system
Big complicated, in addition extension upgrading many times, so constructing the primary time also can be very very long, the number of failure also can be significantly
Increase, if building process mistake, investigation problem also can be extremely difficult.In addition the subtle modification in any point made to system is all
It needs to rebuild whole system, redeploy.One system of multiple developer's joint developments, it is also necessary to other be waited to open
Hair personnel could dispose after the completion, this greatly reduces the flexibility of team and function delivery frequency；(11) it is in addition beaten in project
Very slow, system is opened and runs to be difficult to develop, test, continuous integrating difficulty, deployed environment dependence complexity, technology stack binding,
Programming language, frame, the upgrading of database and replacement are extremely difficult etc..
How these problems are coped with, to the flexibility of software systems, opening, maintainability, scalability and software
System made higher requirement the respond of market and client.How rapidly to increase, extend, upgrade current mark
Quasi- system function is that client is customized, and effectively ensures and promote software development quality and development efficiency, is had become
The significant challenge of Software Industry.

Customer ID (systems buying person), class method manes mark, language used.
(3) judge whether have existed in NoSql script storage repository (Redis) according to this uniqueness cryptographic Hash.
(4) if be not present in NoSql script storage repository, step (6) is jumped to
(5) if existed in NoSql script storage repository, (eight) are jumped to.
(6) if not compiling syntax error, service logic scripted code is saved in NoSql script storage repository.
(7) if there is compiling syntax error, then step (8) is jumped to
(8) script adder is based on context prompted, presence is already present in NoSql script storage repository or compiles
Syntax error or addition are edited successfully, and step (1) is jumped to, and are operated again newly, for customized extension interception service logic
Behavior allows to be inserted into unlimited and intercepts, intercepts the sequence executed according to the suitable of configuration before and after functions of modules method Method
Sequence successively executes, can also extension after addition at any time intercept execution sequence is adjusted in list at any time or it open or
Deactivate or edit again replacement.
Such as the service logic of addition intercepts code for realizing Rest service, addition interface is as shown in figure 12, can be by step
It is rapid simple and efficient.The interface for adding service logic interception code is as shown in figure 13, and addition service logic intercepts the data source of code
Code interface is as shown in figure 14.
As shown in Figure 10 A, 10B, compared to the implementation of the fixation of traditional application program system, i.e., each function mould
The module that interface provided by block and realization define before being all, cannot be in the operational process of program according to some conditions
Judge to dynamically change the behavior of program or extension and add new function.The present invention can system the time of running according to fortune
Row environmental context is to determine whether need change or the behavior of extender.And in the program of dynamic script engine architecture
In, the division between dynamic script engine management program and dynamic script is very clearly dynamic script engine management program
Dynamic script functional template can be completely independent exploitation or third company exploitation, this is conducive in large-scale software development mistake
Cheng Zhong carry out exploitation can parallel, improve the efficiency and quality of exploitation.And in exploitation and debugging process, when part is dynamic
When problem occurs for state script module, due to relatively independent between each dynamic script card module, it is not interfered with
His module, is beneficial to the development and progress of Experience of Software Testing Work, convenient for solution of finding the problem during test and debugging
Problem.In addition, the modification to partial dynamic script, does not interfere with other dynamic scripts, avoids and draw because of righting a wrong
Out the case where new problem, and system can dynamically replace component at run time, according to the variation of running environment or certain
Condition and cause new behavior, thus dynamically improve software systems adaptivity.
It is complete using dynamic script adding module and scripted code spreading code processing module that service logic, which intercepts code,
At as shown in figure 5, satisfactory code is stored into dynamic script code storage by dynamic script code storage module.
Interception label and service logic, which intercept after code adds, can form multilingual dynamic script code listing, such as scheme
Shown in 11.
It should be noted that blocking apparatus code and service logic intercept code in the presence of difference substantially, service logic
Intercept the function that extend for realizing system of code, can real-time perfoming change, carry out cloud by remote server and compile to realize
Operation；And blocking apparatus code is a shell, only one section of weaving program, is specifically directed to and needs Remote Expansion
In method, local compiling is carried out, the logical code really write, i.e. service logic intercept code and be not included in this interception dress
It sets inside code.Such as blocking apparatus code here is such as: RunDynamicScript (" SendSms ", " 13011199191 ",
" it is short message that you, which get well this, ")；But the actual functional capability code (i.e. service logic interception code) for sending short message is in remote server.It compiles
Operation is translated to specifically comprise the following steps, as shown in Figure 3:
1) calling service functions of modules method, system extend interception parameter from high speed according to operation system functions of modules point
Extension is judged whether there is in caching Redis to intercept and (only take System level business logical extension and ought be up till now for initiate mode
The individual business logical extension of client).The extension interception parameter of transmitting mainly has: service logic scripted code mark, system
Mark, customer ID (systems buying person), the contextual informations such as class method manes mark and method parameter.
If 2) detection has extension and intercepts, by system banner, customer ID (systems buying person), class method manes mark etc.
Information transmitting reads extension from script NoSql storage repository according to these marks and intercepts the information such as scripted code, and does script generation
Code uniqueness Hash.These information include: that extension intercepts language；Extension intercepts code；Extend interception mode: synchronous intercepting, different
Step intercepts；It intercepts code and executes time-out time；It intercepts code error process mode: interrupting, continues to run；Intercept rank:
System-level interception, client level intercept；
3) scripted code uniqueness Hash is intercepted according to extension, whether compiled the scripted code from detection memory be real
Example (there is no compiled examples, then have two may, first, operation for the first time, only compile it is primary, second, extension intercept script
Code is replaced by editor's needs that change).Dynamic script is loaded into frame system and creates the original that example is abided by
It is then: is loaded into again when operation, does not need or need to replace just to unload script module, can reduce so interior
The occupancy deposited.
If 4) extend in memory there are this and intercept scripted code example, 6 are jumped.
5), if there is no this extensions to intercept scripted code example in memory, jumps 11.
6) it is read from memory and positions compiled memory instance.
7) dynamic script enforcement engine is identified according to class method manes and the contexts such as method parameter, used language are believed
Breath runs simultaneously specified function method (if it is asynchronous operation, then by multilingual dynamic script enforcement engine driving running example
Handled and run by other thread queues on backstage), delivery protocol uses thrift.
8) if operation exception occurred or more than the specified time, 9 are jumped to.
9) system asynchronous record running log & performance, time-consuming situation, exception information return.
10) normal operating results return, and jump to 12.
11) counter is added 1 by dynamic script example, and updates last allocating time.
12) system is detected whether to have extension again or be intercepted, and jumps to 1.Multiple extensions intercept the execution of scripted code
As a result the last one is directly returned, and before and intermediate implementing result can be added to what system especially provided
The current execution thread slot data (ApplicationContextDataSlot) of ApplicationContext, can be in process
Or long-range transmitting middle back and forth obtains.
Above-mentioned implementation procedure is extended suitable for teleaction service, while being suitable for local service and being extended, as shown in Figure 7,8, by
Multilingual dynamic script code compilation engine device and enforcement engine device are completed compiling and are executed, and wherein running example is stored in
In memory, operates in script and exist in script warehouse.Blocking apparatus is extended for realizing intercepting label and intercepting code
Addition.
Wherein generate extension intercept scripted code example the following steps are included:
(1) extension is read from NoSql script storage repository and intercept scripted code, wherein the construction in script warehouse such as Fig. 4 institute
Show.
(2) extension is intercepted into scripted code and is loaded into multilingual dynamic script compiler engine.Different language, is loaded onto not
It is compiled in same compiler engine.
(3) load extension intercepts external relating module and resource required for language and is compiled.Complicated service logic,
Usual one section of scripted code is impossible, the common compiling of the resources such as external dll or jar that need to rely on participation.
(4) the memory byte after compiling is placed in memory and instantiated and do corresponding initialization operation.
Above-mentioned compilation run method by dynamic script code blocking module server end, dynamic language management engine module with
And the operation calling module cooperation of dynamic script example is completed, as shown in figure 5, operation time-out time is by the extremely overtime mould of dynamic script
Block performs corresponding processing.
To the calling of dynamic script example, there are two types of modes: event is called and automatic is called.Event calling refers to certain spy
Fixed event message is triggered, and if the mouse of user is when clicking some function point, this is operated the method etc. called below
Extension intercept information passes to system framework, and corresponding dynamic script instance processes operation is called in system judgement.It is automatic to call
Be then system can according to the needs of system itself or the needs of user, when reaching some time point or when some condition or
By certain time interval (per second/minute/hour/week/moon), system framework automatic trigger intercepts scripted code to dynamic expansion
Example is called or automatically in running background.The calling process that system framework intercepts scripted code example to dynamic expansion is:
Dynamic script example is first carried out, then judges whether there is next extension intercept point, if there is extension point in extension again
Or have parallel other extension points, then it continues to execute down, these extension intercept points are formed one and have an opportunity to expand in this way
Chain is opened up, to extend different function required for completion system and client.
The personalized customization service logic of client there may come a time when it is more complicated, utilize extension intercept scripted code service logic
Unloading mechanism, memory source occupancy can be greatly reduced to a certain extent, specific unloading mechanism includes the following steps:
1) counter and last allocating time are set for each dynamic script example.
2) it calls a dynamic script example that counter is added 1, and updates last allocating time.
3) according to timing detection counter and last allocating time within the specified period is configured, specified calling time will be less than
The dynamic script example addition removal mark of several and big never call always at fixed time.
4) system by the dynamic script example for the mark for having removal the dynamic offloading from memory, wherein this step is by dynamic foot
This example Unload module or dynamic script example replacement module are completed, as shown in Figure 5.
Determine as shown in fig. 6, operation system of the invention carries out operation expanding point by the setting that service logic intercepts code
Justice later in corresponding extension point addition blocking apparatus code, and is stored into script warehouse.At runtime, by multilingual script
Compiling/enforcement engine is from script warehouse Download Script and controls the compiling that relating module outside associated language carries out multilingual code
And it runs, the online extension of finishing service system function.
