We can get the full path to the jar package by code and then get the version number by intercepting the string.

We need to use one of the classes contained in the JAR package.

String jarpath = SqlSession.class.getProtectionDomain (). Getcodesource (). GetLocation (). GetFile ();
Get/x:/xxxx/xx/mybatis-3.2.8.jar

The string is then processed.
