detailed description

In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

Referring to FIG. 1 , this figure shows the flow of an embodiment of the method for extracting a Java network application upgrade package according to the present application. This example includes:

Step S101: Determine the directory of the upgrade package and the modified source program file to realize the upgrade of the Java network application;

The upgrade package directory is used to place the program files that need to be updated and upgraded. This directory should be predetermined in extracting the Java network application upgrade package. It should be noted that the "upgrade" referred to in this embodiment not only includes the version upgrade of the Java network application (i.e. Launch a new generation of Java network applications), and include supplements and improvements to the loopholes or defects of Java network applications; the modified source program files are program codes that realize the upgrade of Java network applications, and making upgrade packages means compiling these program codes . There are many ways to determine the upgrade package directory and the modified source program file. It can be manually set or configured according to preset rules through automated equipment. For example, the upgrade package directory and the modified source program file can be configured through a special configuration file config.xml. source program files. In some cases, if the project source program directory changes, it is also necessary to configure the project source program directory according to the actual situation. Exemplary program codes for configuring the project source program directory, upgrade package directory, and modified source files through configuration files are as follows:

This program section configures the project source program directory as D:\\ProgramFiles\\SoTowerStudio1.5.1_07\\eclipse\\workspace\\jjjc, configures the upgrade package directory as E:\\a, and sets the modified source program file List readme.txt to record the modified source program file, and realize the record in txt file format.

Step S102: Write the file name of the modified source program file into the list of modified source program files in the form of a relative path;

After determining the upgrade package directory and the modified source program file, write the file name of the modified source program file into the list of modified source program files in the form of a relative path, where the "relative path" is relative to the absolute path Yes, the root directory of the "relative path" is determined by the root directory of the Java web application. Usually, there are multiple modified source program files involved in the Java network application upgrade process. Therefore, this embodiment sets a list of modified source program files to record the paths of these multiple files. Refer to the following code segment, which writes two source program files to the modified file list readme.txt, namely TaskInfoStub.java and main.jsp. It should be noted that the file names here should be according to the field The full name of the file determined by the technical knowledge it belongs to includes the part of the original name (file name) of the file and the extension of the file. Only the source program file with the extension can be recognized:

src\com\portal\task\shandong\TaskInfoStub.java/

WebContent\jjjc\lzjs\main.jsp

Step S103: assemble the compiled file path according to the relative path of the modified source program file;

The compiled file path is the absolute path, which is determined by the relative path of the modified program file and the project source program directory (project development directory). Usually, the project source program directory can use the default directory, so that Directly assemble the compiled file path based on the relative path and the default project source program directory. However, in some cases, the project source program directory changes. At this time, the project source program directory can be preset, such as the project development directory shown in the previous example: D:\\ProgramFiles\\SoTowerStudio1.5.1_07\\eclipse\\workspace \\jjjc. When the relative path of the modified source program file is "src\com\portal\task\shandong\TaskInfoStub.java", the absolute path after assembly is: "D:\ProgramFiles\SoTowerStudio1.5.1_07\eclipse\workspace\ jjjc\src\com\portal\task\shandong\TaskInfoStub.java".

Step S104: Find the file with the same name as the modified source program file under the compiled file path;

Step S105: writing the file with the same name into the upgrade package directory to realize the extraction of the Java network application upgrade package;

After the file with the same name is found through the preceding steps, it means that the file needs to be updated and upgraded, and it is written into the upgrade package target directory, so as to realize the extraction of the Java network application upgrade package. Specifically, writing the file with the same name into the upgrade package directory can be implemented by using the Java function (method) fileCopyToSourceFile(). Taking the upgrade package directory mentioned above as an example, the effect after writing the file with the same name into the upgrade package directory is shown in Figure 2: there are another folders under E:\a, one is the src folder, and the other is the is the WebContent folder.

In this embodiment, after the upgrade package directory and the modified source program file are determined, the file name of the modified source program file is written into the file list with a relative path, and then the file path is assembled through the relative path, and then the file path is searched under the path. File with the same name, write the file with the same name into the upgrade package directory to realize the extraction of the Java network application upgrade package. Compared with the prior art, this embodiment only records the relative file path of the modified source program file, obtains the file with the same name through the relative file path, copies the file with the same name under the upgrade package directory, and avoids introducing No source files have been modified, thereby compressing the "volume" of the upgrade package, saving storage resources and transmission resources, and improving the efficiency of extracting Java network applications as a whole.

The above-mentioned embodiments can better realize the purpose of the invention of the present application, but in some cases, the above-mentioned embodiments can be further improved and deformed based on some special needs. For example, after writing the file name of the modified source program file into the list of modified source program files in the form of a relative path, the above embodiment may also include the step of verifying whether these files exist according to the file name in the file list. If these files exist, steps such as extracting the upgrade package are performed, and if they do not exist, relevant error messages can be prompted. The verification process can use the File.exists() function (method) of Java to determine whether the modified source file exists. Referring to Fig. 3, this figure shows the result of the verification step performed by the above embodiment.

For another example, after the above-mentioned embodiment writes the file with the same name into the upgrade package directory, it can also count the number of files in the upgrade package directory, so as to check whether the extraction of the upgrade package is successful and whether there are any missing files. Referring to FIG. 4 , this figure shows a schematic diagram after counting upgrade package directory files.

In the actual application of the above-mentioned embodiment, it may be encountered that the modified source program file contains a Java class file, and the extension of the Java class file is .class after compilation. In this case, if the compiled embedded class has a file with the same name , the file with the same name must be distinguished, otherwise it may cause an error in extracting the upgrade package. There are many ways to distinguish files with the same name. Preset rules can be set first. After this step is executed, the automated information processing equipment will automatically distinguish files with the same name according to the preset rules. The rule can be to add numbers and letters after the class file name characters, or other symbols.

The aforementioned embodiments describe in detail the embodiment of the method for extracting the Java network application upgrade package of the present application, and accordingly, the present application also provides an embodiment of the device for extracting the Java network application upgrade package.

The working process of this device embodiment is: after the directory file determination unit 401 determines the upgrade package directory and the modified source program file to realize Java network application upgrade, the file name of the modified source program file is written by the file name writing unit 402 as The relative path form is written into the modified source program file list, and then the file path assembly unit 403 assembles the compiled file path according to the relative path of the modified source program file in the file list, and the file with the same name search unit 404 searches for the compiled file path. A file with the same name as the modified source program file under the file path; the file with the same name writing unit 405 writes the file with the same name into the upgrade package directory to realize the extraction of the Java network application upgrade package.

In this device embodiment, after determining the upgrade package directory and the modified source program file, the file name of the modified source program file is written into the file list with a relative path, and then the file path is assembled through the relative path, and then the Find the file with the same name, and write the file with the same name into the upgrade package directory to realize the extraction of the Java network application upgrade package. Compared with the prior art, this device embodiment only records the relative file path of the modified source program file, obtains the file with the same name through the relative file path, copies the file with the same name to the upgrade package directory, and avoids the The source files that have not been modified are introduced, thereby compressing the "volume" of the upgrade package, saving storage resources and transmission resources, and improving the efficiency of extracting Java network applications as a whole.

In order to meet some special needs, some corresponding functional structural units may be added to the aforementioned device embodiments. For example, after the file name of the modified source program file is written into the list of modified source program files in the form of a relative path, a file verification unit 406 can be added to verify whether the modified source program file exists, if If it exists, the file path assembly unit is triggered, and then the subsequent functional units are triggered. If it does not exist, an error alarm can be provided.
