Question:

Recently, there is data garbled when deploying the project. After checking that the project uses the UTF-8 encoding format, so is the data, but the garbled code is passed to the other party after calling the API.

Because it is deployed in Windows environment, Windows encodes GBK by default, which leads to the problem of inconsistent jvm runtime coding, and it is easy to modify.

Solution:

If you use UTF-8 encoding in Linux environment, you don't have to modify it, because Linux defaults to UTF-8

The war package is deployed on Tomcat

Modify jvm coding

Linux environment

Configure in catalina.sh

JAVA_OPTS= "$JAVA_OPTS-Dfile.encoding=utf-8"

Because the default encoding format in the Windows environment is GBK, you need to modify the Tomcat runtime encoding format.

Windows environment

Configure in catalina.bat

Set JAVA_OPTS=%JAVA_OPTS%-Dfile.encoding=UTF-8

For jar package deployment, you only need to add the jvm parameter to the startup command.

Jar package deployment

Start command to add jvm parameter

Java-Dfile.encoding=UTF-8-jar xxx.jar

Summary

The above is the editor to introduce to you to modify the Tomcat runtime jvm coding problems, I hope to help you!
