3、启动类

  1.   @EnableDiscoveryClient
  2.   @SpringBootApplication
  3.   @MapperScan("zss.springcloud.dao")
  4.   public class AuthorityApplication {
  5.       public static void main(String[] args) {
  6.           SpringApplication.run(AuthorityApplication.class, args);
  7.       }
  8.   }
  9. ```java



  13. 4、junit测试类
  14. ```java
  15. @SpringBootTest(classes = AuthorityApplication.class)
  16. @RunWith(SpringRunner.class)
  17. public class MyTest {
  18.     @Resource
  19.     private SpringApplication application;
  20.     @Test
  21.     public void test01(){
  22.         System.out.println(123);
  23.     }
  24. }
复制代码
