[0049] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only constitute a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0050] At present, in order to reduce the workload of developers and operation and maintenance personnel, facilitate the management of configuration files, all jar files required by the WEB application are placed in the standard jar file library, the structure of the WEB application is adjusted, the size of the WEB application is increased, and the operation and maintenance work becomes very difficult, tedious and redundant. Therefore, the application provides an external class library loading method based on an application server, avoids placing part of the jar files of the WEB application in an external directory, and increases the operation and maintenance workload and the tedious configuration file operation.

[0051] Referring to Figure 1 The embodiment of the application discloses an external class library loading method based on an application server, which comprises the following steps:

[0052] In step S11, the initial standard deployment description file is configured with an external class path attribute to obtain a target standard deployment description file, and the target standard deployment description file is placed in a preset application program; the external class path attribute is an attribute of an absolute path of an external class library directory or an absolute path of an external software package file; the external class library directory comprises the external software package file.

[0053] In this embodiment, a class loading tag is added to the initial standard deployment description file, and an attribute of an absolute path of an external class library directory or an attribute of an absolute path of an external software package file is configured in the class loading tag to obtain a target class loading tag, the target class loading tag is added to the initial standard deployment description file to obtain a target standard deployment description file, and the target standard deployment description file is placed in a preset application program. Specifically, the initial standard deployment description file is configured with an external class path attribute to obtain a target standard deployment description file, and the target standard deployment description file is placed in a preset application program, comprising: configuring the absolute path of the external class library directory or the absolute path of the external software package file through the class loading tag to obtain a configured target class loading tag, and adding the target class loading tag to the initial standard deployment description file to obtain a target standard deployment description file; and placing the target standard deployment description file in a standard folder of the preset application program.

[0054] In a specific embodiment, the external class path attribute extra-class-path is configured in the class loading tag, the absolute path of the external class library directory or the absolute path of the external jar file is configured based on the external class path attribute, and multiple directory paths or multiple jar file paths are separated by semicolons. Part of the jar files of the WEB application is placed in the / opt / extraRepository directory, and can be configured as follows: <class-loader extra-class-path=" / opt / extraRepository" / >; and placing the configured inforsuite-web.xml (i.e. target standard deployment description file) into the WEB-INF (i.e. standard folder) directory of the WEB application (i.e. preset application).

[0055] In step S12, the preset application is parsed by using the class loader to obtain the standard directory class library, the standard software package file library and the target standard deployment description file of the preset application, and the standard directory class library and the standard software package file library are added to the first preset class path of the class loader in sequence by using the first preset adding class library strategy.

[0056] In the embodiment, the preset application is parsed by using the class loader created by the application server to obtain the standard directory class library, the standard software package file library and the target standard deployment description file of the preset application, and the standard directory class library is placed into the file array and the standard software package file library is placed into the software package file array. Specifically, the preset application is deployed to the application server, and the class loader corresponding to the preset application is created by using the application server; the preset application is parsed based on the class loader to obtain the standard directory class library, the standard software package file library and the target standard deployment description file of the preset application; and the standard directory class library and the standard software package file library are respectively stored into the file array and the software package file array.

[0057] It can be understood that the configured WEB application is deployed to the application server, and at the beginning of the deployment, the application server first creates the corresponding WebappClassLoader (i.e. class loader) for the WEB application. The WebappClassLoader first parses the deployed application, reads the standard directory class library and the standard jar file library (i.e. standard software package file library) of the WEB application. The standard directory class library (generally only one, i.e. WEB-INF / classes directory) of the WEB application is stored in the file array; the standard jar file library of the WEB application is stored in the jar file array, and then the standard directory class library and the standard jar file library are added to the class path of the WebappClassLoader in sequence by calling the adding class library method of the WebappClassLoader.

[0058] Step S13, reading the target standard deployment description file based on the class loader to obtain a path value corresponding to an external class path attribute, and storing the path value into an external class path string.

[0059] In this embodiment, the class loader of the application server parses the target standard deployment description file to obtain the class loading tag, reads the class loading tag to obtain a path value corresponding to an external class path attribute, and stores the path value into an external class path string. In a specific implementation, after the application server reads the standard directory class library and the standard jar file class library, the WebappClassLoader parses the inforsuite-web.xml file to read the class loading tag, reads the value of the external class path configured by the extra-class-path attribute, and stores it in the external class path string.

[0060] Step S14, splitting the external class path string to obtain an external class path element, and storing the external class path element into an external class path element array.

[0061] In this embodiment, the external class path string is split by a semicolon using a preset string splitting strategy of a software development kit to obtain an external class path element, and the external class path element is stored into an external class path element array. Specifically, the splitting of the external class path string to obtain an external class path element and storing the external class path element into an external class path element array includes: splitting the external class path string using a preset string splitting strategy of a software development kit according to a preset string splitting rule to obtain a corresponding external class path element; and storing the external class path element into an external class path element array.

[0062] It can be understood that after obtaining the external class path string, a string splitting method of a JDK (i.e., a software development kit) can be called to split the external class path string into multiple external class path elements by a semicolon, and the external class path elements are stored in an external class path element array. At this point, the external class path configured by the extra-class-path attribute has been completely parsed and stored in the external class path element array.

[0063] Step S15, traversing the external class path elements in the external class path element array, obtaining the external software package file based on the judgment result of whether the traversed external class path element is the external class library directory, and adding the external software package file to a second preset class path of the class loader in sequence using a second preset class library adding strategy.

[0064] In the embodiment, the external class path elements in the external class path element array are traversed, and it is determined whether the traversed external class path element is the external class library directory by using a preset directory judgment method of a file class, so as to obtain the external software package file based on the determination result, and the external software package file is sequentially added to the second preset class path of the class loader by using a second preset class library adding strategy. Specifically, the traversal of the external class path elements in the external class path element array, the obtaining of the external software package file based on the determination result of whether the traversed external class path element is the external class library directory, and the sequential addition of the external software package file to the second preset class path of the class loader by using the second preset class library adding strategy include: the external class path elements in the external class path element array are traversed by using a preset loop traversal strategy; it is determined whether the traversed external class path element is the external class library directory by using a preset directory judgment method of a file class; the external software package file is obtained based on the determination result, and the external software package file is sequentially added to the second preset class path of the class loader by using a second preset class library adding strategy.

[0065] It can be understood that all the external class path elements in the external class path element array can be traversed by using a JDK loop traversal method, each of the external class path elements is first used to create a file class of JDK by using a new keyword, then a directory judgment method of the file class is called to determine whether the traversed external class path element is the external class library directory, the external software package file obtained based on the determination result is sequentially added to the second preset class path of the class loader.

[0066] Further, it is judged whether the external class path element is the external class library directory through the preset directory judgment mode of the file type. If the external class path element is the external class library directory, the external software package file is obtained by reading the external class library directory. If the external class path element is not the external class library directory, the external class path element is determined as the external software package file, and the obtained external software package file is added to the second preset class path of the class loader. Specifically, the external software package file is obtained based on the judgment result, and the external software package file is sequentially added to the second preset class path of the class loader by using the second preset adding class library strategy. If the external class path element is the external class library directory, the file reading is performed from the external class library directory based on a preset file listing strategy to obtain each external software package file. Each external software package file is traversed and added to the second preset class path of the class loader by using the adding class library mode of the class loader. If the external class path element is not the external class library directory, the external class path element is determined as the external software package file, and the external software package file is added to the second preset class path of the class loader by using the adding class library mode of the class loader.

[0067] It can be further understood that it is judged whether the external class path element is the external class library directory. If the external class path element is the external class library directory, the file listing method of the file type is called to read all external jar files under the external class library directory, and then all external jar files are traversed and added to the class path of the WebappClassLoader by calling the adding class library method of the WebappClassLoader. If the external class path element is not the external class library directory, i.e., the external jar file, the adding class library method of the WebappClassLoader is directly called to add the external jar file to the class path of the WebappClassLoader.

[0068] In step S16, the corresponding target software package file is loaded from the first preset class path and the second preset class path by using a preset loading class strategy during the running of the preset application program.

[0069] In the embodiment, during the running of the preset application, the corresponding target software package file is loaded from the first preset class path and the second preset class path by calling the class loading method of the class loader. Specifically, during the running of the preset application, the corresponding target software package file is loaded from the first preset class path and the second preset class path by a preset class loading strategy, including: during the running of the preset application, the corresponding target software package file is loaded from the standard directory class library in the first preset class path, the standard software package file library and the external software package file in the second preset class path by calling the class loading method of the class loader.

[0070] It can be understood that during the running of the WEB application, the class file is searched from the class path by calling the class loading method of the WebappClassLoader, that is, the required class file is searched from the standard directory class library, the standard jar file library and the external class library in sequence. The external class library includes all external software package files.

[0071] As can be seen from the above, the target standard deployment description file including the external class library directory is put into the preset application, and then the preset application is parsed by using the class loader to obtain the path value corresponding to the external class path attribute, and the path value is stored to the external class path string. The external class path string is segmented to obtain the external class path element, and the external class path element is stored to the external class path element array. Then, the external class path elements in the external class path element array are traversed, and the external software package file is obtained based on the judgment result of whether the traversed external class path element is the external class library directory. The external software package file is sequentially added to the second preset class path of the class loader. In this way, during the running of the preset application, the corresponding target software package file can be loaded based on the second preset class path, without the need to sequentially configure the absolute paths of the external software package files under the external class library directory, thereby enhancing the usability of the application server, making the subsequent operation and maintenance of the application server and the WEB application simple and easy to implement, and reducing the workload of the developers and the operation and maintenance personnel.

[0072] As can be seen from the above embodiment, the target standard deployment description file and the created class loader are configured to implement the search of the external class file, and therefore, the process of searching the class file from the external class library based on the target standard deployment description file and the class loader is described.

[0073] Figure 2 A specific external class library loading method based on an application server provided for the embodiment includes:

[0074] First, the initial standard deployment description file is configured to obtain a target standard deployment description file. Specifically, a class loading tag is added in the initial standard deployment description file, and an external class path attribute is configured based on the class loading tag, that is, a path attribute of an absolute path of an external class library directory or a path attribute of an absolute path of an external software package file is configured in the class loading tag to obtain a target class loading tag. The target class loading tag is added to the initial standard deployment description file to obtain a configured target standard deployment description file, and the target standard deployment description file is put into a preset application. The preset application is deployed to an application server, and a class loader corresponding to the preset application is created based on the application server. The class loader is used to read a standard class library of the preset application, the standard class library includes a standard directory class library and a standard software package file class library, and the standard directory class library and the standard software package file class library are added to a first preset class path of the class loader.

[0075] Then, the preset application is parsed by the class loader to obtain a target standard deployment description file, a path value corresponding to an external class path attribute is obtained by reading the target standard deployment description file, the path value is stored in an external class path string, the external class path string is segmented to obtain an external class path element, and the external class path element is stored in an external class path element array. Then, the external class path elements in the external class path element array are traversed, and the external software package file is obtained based on a judgment result of whether the traversed external class path element is the external class library directory. The external software package file is sequentially added to a second preset class path of the class loader. In this way, during the running of the preset application, the absolute path of the external software package file under the external class library directory does not need to be sequentially configured, and the target software package file can be loaded based on the second preset class path. This not only enhances the usability of the application server, but also makes the subsequent operation and maintenance of the application server and the WEB application simple and easy, thereby reducing the workload of the developers and the operation and maintenance personnel.

[0076] Correspondingly, referring to Figure 3 The application also provides an external class library loading device based on an application server, which comprises:

[0077] A target file configuration module 11 is configured to configure an external class path attribute of an initial standard deployment description file to obtain a target standard deployment description file, and put the target standard deployment description file into a preset application.

The external class library directory comprises the external software package file.

[0078] The application program parsing module 12 is configured to parse the preset application program by using the class loader to obtain a standard directory class library, a standard software package file library and the target standard deployment description file of the preset application program, and add the standard directory class library and the standard software package file library to a first preset class path of the class loader in sequence by using a first preset adding class library strategy.

[0082] The class file loading module 16 is configured to load a corresponding target software package file from the first preset class path and the second preset class path by using a preset loading class strategy during running of the preset application program.

[0083] As can be seen from the above, the target standard deployment description file including the external class library directory is put into the preset application program, and then the preset application program is parsed by using the class loader to obtain a path value corresponding to the external class path attribute, and store the path value to an external class path string. The external class path string is segmented to obtain an external class path element, and the external class path element is stored to an external class path element array. Then the external class path element in the external class path element array is traversed, and the external software package file is obtained based on a judgment result of whether the traversed external class path element is the external class library directory. The external software package file is added to the second preset class path of the class loader in sequence. In this way, during running of the preset application program, the corresponding target software package file can be loaded based on the second preset class path, without the need to configure the absolute paths of the external software package files under the external class library directory in sequence, thereby enhancing the usability of the application server, making the subsequent operation and maintenance of the application server and the WEB application simple and easy to implement, and reducing the workload of the developers and the operation and maintenance personnel.
