[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] At present, in order to reduce the workload of developers and operation and maintenance personnel and facilitate the management of configuration files, all jar files required by WEB applications are placed in the standard jar file class library, and the structure of the WEB application is adjusted, which increases the size of the WEB application and makes the operation and maintenance work very difficult, cumbersome, and redundant. To this end, the present application provides an external class library loading method based on an application server, which avoids the increase in operation and maintenance workload and cumbersome configuration file operations caused by placing some jar files of the WEB application in an external directory.

[0051] See also Figure 1 As shown, the embodiment of the present invention discloses a method for loading an external class library based on an application server, comprising:

[0052] Step S11, configuring the external class path attribute of the initial standard deployment description file to obtain a target standard deployment description file, and placing the target standard deployment description file into a preset application; 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 includes the external software package file.

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

[0054] In a specific implementation, the external class path attribute extra-class-path is configured in the class loading tag, and 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. Some jar files of the WEB application are placed in the / opt / extraRepository directory, which can be configured as follows: <class-loader extra-class-path=" / opt / extraRepository" / >;Put the configured inforsuite-web.xml (i.e. the target standard deployment description file) into the WEB-INF (i.e. the standard folder) directory of the WEB application (i.e. the preset application).

[0055] Step S12: parse the preset application using a class loader to obtain a standard directory class library, a standard software package file class library, and the target standard deployment description file of the preset application, and sequentially add the standard directory class library and the standard software package file class library to the first preset class path of the class loader using a first preset class library addition strategy.

[0056] In this embodiment, the class loader created by the application server is used to parse the preset application to obtain the standard directory class library, standard software package file class library and the target standard deployment description file of the preset application, and the standard directory class library is placed in the file array, and the standard software package file class library is placed in the software package file array. Specifically, the class loader is used to parse the preset application to obtain the standard directory class library, standard software package file class library and the target standard deployment description file of the preset application, including: deploying the preset application to the application server, and using the application server to create a class loader corresponding to the preset application; parsing the preset application based on the class loader to obtain the standard directory class library, standard software package file class library and the target standard deployment description file of the preset application; and storing the standard directory class library and the standard software package file class library in the file array and the software package file array respectively.

[0057] It is understandable that when deploying a configured WEB application to an application server, at the very beginning of the deployment, the application server will first create a corresponding WebappClassLoader (i.e., class loader) for this WEB application. The WebappClassLoader will first parse the deployed application and read the standard directory class library and standard jar file class library (i.e., standard package file class library) of the WEB application. Among them, the standard directory class library of the WEB application (usually only one, i.e., the WEB-INF / classes directory) is stored in the file array; the standard jar file class library of the WEB application is stored in the jar file array, and then by calling the add class library method of the WebappClassLoader, the standard directory class library and the standard jar file class library are added to the class path of the WebappClassLoader in turn.

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

[0059] In this embodiment, the target standard deployment description file is parsed by the class loader of the application server to obtain the class loading tag, and the class loading tag is read to obtain the path value corresponding to the external class path attribute, and the path value is stored in the 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, 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: Segment the external class path character string to obtain external class path elements, and store the external class path elements into an external class path element array.

[0061] In this embodiment, the external class path string is segmented with semicolons using the preset string segmentation strategy of the software development kit to obtain external class path elements, and the external class path elements are stored in the external class path element array. Specifically, the segmentation of the external class path string to obtain external class path elements and the storage of the external class path elements in the external class path element array includes: using the preset string segmentation strategy of the software development kit and segmenting the external class path string according to the preset string segmentation rules to obtain corresponding external class path elements; storing the external class path elements in the external class path element array.

[0062] It is understandable that after obtaining the external class path string, the string splitting method of JDK (Software Development Kit) can be called to split the external class path string into multiple external class path elements with semicolons, and store the external class path elements in the external class path element array. At this point, the external class path configured by the extra-class-path attribute has been fully parsed and stored in the external class path element array.

[0063] Step S15: traverse the external class path elements in the external class path element array, obtain the external software package file based on a judgment result of whether the traversed external class path element is the external class library directory, and use the second preset class library addition strategy to sequentially add the external software package files to the second preset class path of the class loader.

[0064] In this embodiment, the external class path elements in the external class path element array are traversed, and a preset directory judgment method of the file class is used to judge whether the traversed external class path element is the external class library directory, so as to obtain the external software package file 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 class library addition strategy. Specifically, traversing the external class path elements in the external class path element array, obtaining the external software package file based on a judgment result of whether the traversed external class path element is the external class library directory, and sequentially adding the external software package file to the second preset class path of the class loader using a second preset adding class library strategy includes: traversing the external class path elements in the external class path element array using a preset loop traversal strategy; creating a corresponding file class using a preset keyword, and judging whether the traversed external class path element is the external class library directory using a preset directory judgment method of the file class; obtaining the external software package file based on the judgment result, and sequentially adding the external software package file to the second preset class path of the class loader using the second preset adding class library strategy.

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

[0066] Furthermore, it is determined whether the traversed external class path element is the external class library directory through the preset directory judgment method of the file class; if the external class path element is the external class library directory, the external class library directory is read to obtain the external software package file; if the external class path element is not the external class library directory, the external class path element is determined to be 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 obtaining the external software package file based on the judgment result, and sequentially adding the external software package file to the second preset class path of the class loader by using the second preset adding class library strategy, includes: if the external class path element is the external class library directory, reading files from the external class library directory based on the preset listing file strategy to obtain each of the external software package files, traversing each of the external software package files and adding the external software package file to the second preset class path of the class loader by using the adding class library method of the class loader; if the external class path element is not the external class library directory, determining the external class path element as the external software package file, and adding the external software package file to the second preset class path of the class loader by using the adding class library method of the class loader.

[0067] It can be further understood that, it is determined 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 list file method of the file class is called to read all external jar files under the external class library directory, and then all external jar files are looped through, and all external jar files are added to the class path of WebappClassLoader in turn by calling the add class library method of WebappClassLoader; if the external class path element is not the external class library directory, that is, it is an external jar file, the add class library method of WebappClassLoader is directly called to add the external jar file directly to the class path of WebappClassLoader.

[0068] Step S16: 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 using a preset loading class strategy.

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

[0070] It is understandable that during the operation of a WEB application, the class loading method of WebappClassLoader is called to search for class files from the class path, that is, to search for required class files from the standard directory class library, the standard jar file class 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 present application puts the target standard deployment description file including the external class library directory into the preset application, and then uses the class loader to parse the preset application to obtain the path value corresponding to the external class path attribute, and stores the path value into the external class path string, divides the external class path string to obtain the external class path element, and stores the external class path element into the external class path element array; then traverses the external class path element in the external class path element array, and obtains 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 adds the external software package file to the second preset class path of the class loader in sequence. In this way, the corresponding target software package file can be loaded based on the second preset class path during the running process of the preset application, and there is no need to configure the absolute path of the external software package file under the external class library directory in sequence, which enhances the availability of the application server, makes the subsequent operation and maintenance of the application server and WEB application simple and easy, and reduces the workload of developers and operation and maintenance personnel.

[0072] It can be seen from the above embodiments that the present application realizes the search for external class files based on the configured target standard deployment description file and the created class loader. Therefore, the process of searching for class files from an 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 in this embodiment includes:

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

[0075] Then, the class loader is used to parse the preset application to obtain the target standard deployment description file, and the target standard deployment description file is read to obtain the path value corresponding to the external class path attribute, and the path value is stored in the external class path string, and the external class path string is segmented to obtain the external class path element, and the external class path element is stored in the 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 the judgment result of whether the traversed external class path element is the external class library directory, and the external software package file is sequentially added to the second preset class path of the class loader. In this way, during the operation of the preset application, the target software package file can be loaded based on the second preset class path without sequentially configuring the absolute path of the external software package file under the external class library directory, which not only enhances the availability of the application server, but also makes the subsequent operation and maintenance of the application server and WEB application simple and easy, thereby reducing the workload of developers and operation and maintenance personnel.

[0076] Accordingly, see Figure 3 As shown, the present application also provides an external class library loading device based on an application server, comprising:

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

[0083] As can be seen from the above, the present application puts the target standard deployment description file including the external class library directory into the preset application, and then uses the class loader to parse the preset application to obtain the path value corresponding to the external class path attribute, and stores the path value into the external class path string, divides the external class path string to obtain the external class path element, and stores the external class path element into the external class path element array; then traverses the external class path element in the external class path element array, and obtains 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 adds the external software package file to the second preset class path of the class loader in sequence. In this way, the corresponding target software package file can be loaded based on the second preset class path during the running process of the preset application, and there is no need to configure the absolute path of the external software package file under the external class library directory in sequence, which enhances the availability of the application server, makes the subsequent operation and maintenance of the application server and WEB application simple and easy, and reduces the workload of developers and operation and maintenance personnel.
