Modify the jvm encoding problem when Tomcat is running

question:

Recently, garbled data appeared when deploying the project. After checking, the project used the UTF-8 encoding format, and the data was also used. However, when it was transmitted to the other party through the calling interface, it was garbled.

Since it is deployed in a Windows environment, the default encoding of Windows is GBK, which leads to the problem of inconsistent encoding during JVM runtime, and it is also easy to modify.

Solution:

If you use UTF-8 encoding in Linux environment, you do not need to modify it, because Linux defaults to UTF-8

The war package is deployed in Tomcat

Modify jvm encoding

Linux Environment

Configuration in catalina.sh

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

Since the default encoding format in Windows environment is GBK, you need to change the encoding format when Tomcat is running.

Windows Environment

Configuration in catalina.bat

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

If it is a jar package deployment, you only need to add the jvm parameter to the startup command.

JAR package deployment

Add jvm parameters to the startup command

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

Summarize

The above is the editor's introduction to modifying the JVM encoding problem when running Tomcat. I hope it will be helpful to everyone!
