Embodiment
Below in conjunction with accompanying drawing deployment system of the present invention and method are done further detailed description, with the webmastering software system in the field of telecommunications is example, and the network management system in the field of telecommunications can be divided into basic supporting layer Support Layer (SL), ccf layer Framework Later (FL) and application layer Application Layer (AL) as shown in Figure 3.All complicated systems all should have clear and definite level to divide, typical in the ICP/IP protocol stack, level notion in the functional mode is corresponding with the module group in deployment, and layer following (being the module group in deployment) is exactly a functional module one by one, for example: alarm, performance, topology etc.
Functional module extracts from functional mode, can be corresponding to function point one by one on the demand, the present invention is based on this situation and proposed a kind of deployment system with dependence functional module, this system mainly comprises: plug-in unit (PAR Plug-inArchive) and plug-in unit are disposed device.
1, plug-in unit is a kind of novel deployment unit that is equivalent to functional module, and can contain other common deployment unit, thereby possesses the ability of encapsulation complicated applications, and the deployment of complicated applications system can be considered as the deployment of plug-in unit one by one.Plug-in unit PAR is that software module corresponding physical on service end/client realizes in the complication system, is embodied as the set of the file that all files that the developer provided of a software module and modular unit generate in the runtime.
Before the notion that does not propose plug-in unit, the needed various files of software module are scrappy, as jar file, configuration file, run-time file etc., often be dispersed under each catalogue of application system, in order to reach the dismountable purpose of each module, need to do a large amount of work by hand, perhaps use the complex installation program to solve this problem.The present invention proposes after the notion of plug-in unit, can be a plug-in unit with all these integrating documents, the degree of modularity when greatly having strengthened the system deployment operation; In addition, plug-in unit (PAR) is also supported dependence, and the function of oneself is finished in the service that plug-in unit may utilize another plug-in unit to provide.With J2EE is example, even if the deployment unit ear of maximum in the J2EE standard also may not embody a function point fully on disposing; And the dependence between these function points (group), can't describe clear especially at present deployment unit.Therefore, the present invention proposes a kind of new deployment unit: i.e. plug-in unit PAR (Plug-in Archive).Realized the modularization that function point is disposed.
Each all has the information of plug-in unit self, for example: plug-in unit ID, plug-in version, and this plug-in unit relied on the same group in the name (so as to a local dependence tabulation is provided) etc. of other plug-in unit, be very important for the deployer.The information of plug-in unit self can be stored with different modes (file or database etc.).What adopt in the present embodiment is file mode, and each plug-in unit is deposited the information of these plug-in units self by a plug-in unit self-described file (being distinguished with specific file suffixes), and the content of each plug-in unit self-described file is finished by add-in developer.
As follows is exactly the example of a plug-in unit self-described file:
The information such as ID (sign), version, module dependence that comprise module (in deployment for plug-in unit) in this document,
<?xml?version=″1.0″encoding=″GB2312″?>
<par>
<info?name=″example1″version=″1.0″/>
<depend>example2.par</depend>
<depend>example3.par</depend>
</par>
By this file, can know the ID (example1) of plug-in unit, version (1.0), the name of other par (example2.par and example3.par) in the same level of its dependence.
2, plug-in unit is disposed device, and being used to specify needs the scope of disposing in the plug-in unit (PAR), keeps can not increasing the time overhead of system deployment again in the cohesion on realizing the function point structure.
Plug-in unit and plug-in unit are disposed the core that device has constituted deployment system, but in order to dispose large-scale application system, also need some accessories:
A, overall system deployment information, in order to the scope of the plug-in unit PAR that will dispose in the descriptive system, and the sequencing of module group on disposing.These information are that the overall situation is unique in system, can store this information with different modes (file or database etc.), what adopt in the present embodiment is file mode, store with the overall system deployment file, as shown in Figure 4: this document passes through the DeployedPar unit scope of definition part administration plug-in unit usually; Usually define the plug-in unit group by fileset unit, when plug-in unit is disposed the dependence processing, write fileset (plug-in unit group) deployment earlier in front, therefore, the sequencing that the module group is disposed among Fig. 4 is exactly dir1 → dir1/dir2 → dir1/dir3 → dir1/dir4 → dir1/dir5.This document form is simple, and support asterisk wildcard (for example: * or? number etc.), as can be seen from the figure, only need write a few style of writing words, just can define the plug-in unit scope that needs deployment easily.Therefore the user can define the plug-in unit that needs deployment easily in the overall system deployment file.
B, resolver, be responsible for resolution system general plan file (deploy.xml) and one group of plug-in unit self-described file and (adopt file mode in the present embodiment, if adopt slightly difference of database or alternate manner), finish determining of deployment scope, define other plug-in unit tabulations that this plug-in unit relies on, collect all deployment files, a plurality of local dependence tabulations are merged into an overall plug-in unit dependence tabulation, then, according to this tabulation, call plug-in unit deployment device and dispose plug-in unit successively; Plug-in unit is disposed device according to disposing agreement, and which catalogue below the decision plug-in unit will be disposed; Obtain the assembly set that all can be disposed by document scanner then, dispose all assemblies according to type.
The principle that plug-in unit is disposed the dependence processing is:
Dependence between the plug-in unit group (being meant the fileset element in the overall system deployment file) is that the fileset that writes in front disposes earlier.
Dependence within the plug-in unit group is to decide by the dependence that defines in the plug-in unit self-described file (parinfo.xml).
Fig. 2 has described the process flow diagram that the plug-in unit with dependence of the present invention is disposed, and this flow process mainly comprises the steps:
(1) reads general plan file deploy.xml;
(2) by resolving this general plan file, draw the overall plug-in unit tabulation of being disposed;
(3) analyze dependence between the module group (layer);
(4) judge that in fact whether the plug-in unit that will dispose exists, if there is no, unusually withdraw from, if exist, and judge whether there is corresponding self-described file below this plug-in unit, if this plug-in unit does not have corresponding self-described file, then withdraw from unusually, if this plug-in unit has corresponding self-described file, then the self-described file consolidation according to this plug-in unit goes out local dependence chained list;
(5) according to local dependence tabulation, the dependence between the binding modules group (layer) is put out overall dependence chained list in order;
(6) according to overall dependence chained list, call plug-in unit one by one and dispose device, plug-in unit is disposed.
Can learn that by technique scheme the deployment that the present invention is based on plug-in unit is a kind of novel deployment mechanisms, only need revise the overall system deployment information, just can easily realize other deployment of functional module (group) level and go deployment; And other deployment mechanisms all needs from dispose catalogue a large amount of assembly bags of interpolations/deletion could realize the deployment of some assemblies/go deployment;
Overall system deployment information form is simply clear and definite, can allow the deployer be easy to define the functional module scope that needs deployment; Can realize general plan that complication system is disposed by the overall system deployment information;
By introducing Plugin Mechanism, the following deployment of plug-in unit is safeguarded by module developer, and the application deployment person just only needs other deployment of functional module (group) level in the system that is responsible for;
Plug-in unit (PAR) has self descriptiveness, can describe local dependency relationships, the dependence that the deployment personnel only consider higher level (between the functional module group);
Plug-in unit (PAR) is a kind of mode of packing and disposing, but it has surmounted packing again and dispose, and can specify some catalogue (for example: the catalogue at resource file place) not dispose below the PAR; On realizing functional module structure, keep can not increasing the time overhead of system deployment again in the cohesion;
This method effectively reduces the complicacy of system deployment, realizes the modularization deployment; And implement simply, directly perceived, different role (developer, deployer, system operator) only needs to be concerned about configuration file seldom, greatly reduces these roles' technical ability requirement.
