3、启动类@EnableDiscoveryClient
@SpringBootApplication
@MapperScan("zss.springcloud.dao")
public class AuthorityApplication {
      public static void main(String[] args) {
          SpringApplication.run(AuthorityApplication.class, args);
      }
}
```java



4、junit测试类
```java
@SpringBootTest(classes = AuthorityApplication.class)
@RunWith(SpringRunner.class)
public class MyTest {
    @Resource
    private SpringApplication application;
    @Test
    public void test01(){
      System.out.println(123);
    }
}
4、报错信息org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'zss.springcloud.MyTest': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.boot.SpringApplication' available: expected at least 1 bean which qualifies as autowire candidate.
