Java garbled Chinese characters in k8s

Some Java open source frameworks have no problem debugging Chinese locally, but return Chinese garbled characters in the k8s pod.

Check the jvm encoding in the pod

 java -XshowSettings:properties -version

Java printing default encoding

 String defaultCharset = System.getProperty("file.encoding");
 log.info("Default Charset: " + defaultCharset);

Add jvm parameter -Dfile.encoding

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