Garbled characters appear when running java projects through bash/cmd

Question:

No matter how the Java code is uniformly encoded as UTF8, it is completely fine to run in the IDE, but it is packaged into Jar and run through Bash and CMD. , Chinese garbled characters will appear.

Reason:

The default encoding of cmd/bash is GBK.

java -jar project.jar

However, this may cause errors caused by incorrect encoding during java runtime. At this time, we can specify the encoding parameters when running Jar

java -Dfile.encoding=utf-8 -jar project.jar

Three . Package the above commands into a bat

If you have to perform the above two steps every time you start the project, it will actually be very troublesome. We can package the above two steps into a bat batch file. The specific steps are as follows

3.1 Create a txt file in the Jar directory and open it with Notepad

3.2 Write the above command into the txt file and save it

3.3 Modify msgSystemStart.txt to msgSystemStart.bat

##3.4 Run the bat file
