After eclipse changes the file, it accurately locates the changed files, that is, the files that need to be upgraded (such as directly overwriting public_html ).

1. The next cvs_tool.exe software.

2. In the software, "Save to" path writes the path you want to save. It will automatically generate
3. After the file has been saved, there are usually three folders:. explodedear, public_html, and SRC.
1>. Delete the. explodedear folder.
2>. Rename the SRC folder to classes.
3>. Move the renamed classes folder to the WEB-INF folder under public_html.
4>. Delete the logs folder in the WEB-INF.
5>. For the file path of the classes folder, replace the Java file with the classes file.

4. Directly overwrite the directory (such as public_html) to the running project. You can either manually restart or not restart tomcat. (Because Tomcat will automatically scan and reload those files at intervals, but not from time to time)
