How to solve the issue of Chinese gibberish in Tomcat logs?

To solve the issue of garbled Chinese characters in Tomcat logs, you can try the following methods:

1. Set the URIEncoding attribute to UTF-8 in the tag.

<Connector ... URIEncoding="UTF-8" ... />

1. Check the code of the application to ensure that the character encoding is correctly set. In Java code, you can set the character encoding using the following method:

response.setCharacterEncoding("UTF-8");

1. If you are using a custom logging handler (such as log4j), make sure to check the related configuration files to ensure that the character encoding for logging output is set correctly.
2. If the log files of Tomcat are displaying garbled characters, you can try using tools like Notepad++ to open them, then selecting “Encoding” -> “Convert to UTF-8” from the menu, saving the file and reopening it to view.
3. If the above method does not work, you can try modifying the Tomcat startup script and add the following parameters to the startup command to set the JVM character encoding.

-Dfile.encoding=UTF-8

By trying the methods mentioned above, the issue of Chinese garbled characters in Tomcat logs should be resolved. If the problem persists, further analysis of relevant configurations and code may be needed, or consider using other tools to handle log outputs.
