1、添加maven依赖

        <!-- 添加test方便测试--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.13.2</version><scope>test</scope></dependency><dependency><groupId>org.junit.platform</groupId><artifactId>junit-platform-launcher</artifactId><version>1.8.2</version><scope>test</scope></dependency>

2、测试代码

import org.junit.Test;public class MyServiceTest2 {@Testpublic void testMyService() {System.out.println ("测试！！！" );}
}
