SprintBoot项目写测试类报错

@SpringBootTest
public class CodeTest {

    @Resource
    MD5Utils md5Utils;

    @Test
    public void test(){
        String pass = md5Utils.getMD5Offset("e10adc3949ba59abbe56e057f20f883e");
        System.out.println("pass = " + pass);
    }
}

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

        由于项目目录是：main/src/com.aa.bb；测试目录是：main/src/com.aa.cc；

        解决：
        将cc修改成bb即可。
