Completely solve the problem of Chinese garbled code in Web Engineering at one time

One 、IDEA The console is garbled

1. IDEA Set the file code as UTF-8

   

2. modify IDEA The installation directory bin Under the idea.exe.vmoptions and idea64.exe.vmoptions, Add at the end of the line -Dfile.encoding=UTF-8

   <properties>
       <maven.compiler.source>8</maven.compiler.source>
       <maven.compiler.target>8</maven.compiler.target>
       <spring.version>5.3.1</spring.version>
       <!-- Maven  The packaging code is specified as  UTF-8, Avoid random code after the project is deployed to the remote server  -->
       <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
       <!-- Maven  Skip testing when packaging  -->
       <maven.test.skip>true</maven.test.skip>
   </properties>
