2、配置文件

1. server:
   
2.   port: xxxx
   
3.   servlet:
   
4.     context-path: /authority
   
5. spring:
   
6.   application:
   
7.     name: springboot-authority
   
8.   datasource:
   
9.     url: jdbc:mysql://47.98.xxx.xx:3306/springcloud?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&allowMultiQueries=true&nullCatalogMeansCurrent=true

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
   
10. 
    
11. 
    
12. 
    
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. }
