Brief discussion on the main method in Java execution of jar package

Package jar files through OneJar or Maven, use the command:

java -jar ****.jar

The specified main method is always run after execution. If there are multiple main methods in the jar, how to run the specified main method?

Try it with the following command:

java -classpath ****.jar ****.****.className [args]

"****.****" means "package name";
"className" means "class name";
"[args]" means the passed parameter;

Run the main method specified in MANIFEST.MF directly:

java -jar mplus-service-jar-with-dependencies.jar

Run the specified main method:

java -cp mplus-service-jar-with-dependencies.jar com.smbea.dubbo.bin.Console start
