        org.springframework.boot
       			
       
        spring-boot-starter-test
       			
       
        test
       		
      	
     	
     		
      			
       				
        
         org.springframework.cloud
        				
        
         spring-cloud-dependencies
        				
        
         ${spring-cloud.version}
        				
        
         pom
        				
        
         import
        			
       		
      	
     	
     		
      			
       				
        
         org.springframework.boot
        				
        
         spring-boot-maven-plugin

        Spring Snapshots
       			
       
        https://repo.spring.io/snapshot
       			
       				
        
         true
        			
       		
      		
      			
       
        spring-milestones

        spring-snapshots
       			
       
        Spring Snapshots
       			
       
        https://repo.spring.io/snapshot

        https://repo.spring.io/milestone
       		
      	
     
    复制代码

config-server的bootstrap.yml的配置如下：

server:  port: 9010spring:  application:    name: config  cloud:    config:      server:        git:		  #码云的用户名和密码及地址          username: ****           password: ****          uri: https://gitee.com/lijiaxi118/blog-repoeureka:  client:    service-url:      defaultZone: http://localhost:9001/eureka/management:  endpoints:    web:      exposure:        include: "bus-refresh"复制代码

3、SpringCloud Config Client端配置

config-client pom.xml配置如下：


    
    	
     
      4.0.0
     	
     		
      
       org.springframework.boot
      		
      
       spring-boot-starter-parent
      		
      
       2.1.2.RELEASE
      		
       
      	
     	
     
      com.lee.self
     	
     
      user
     	
     
      0.0.1-SNAPSHOT
     	
     
      user
     	
     
      Demo project for Spring Boot
     	
     		
      
       1.8
      		
      
       Greenwich.SR1
      	
     	
     		
      			
       
        org.springframework.cloud
       			
       
        spring-cloud-starter-config
       		
      		
      			
       
        org.springframework.cloud
       			
       
        spring-cloud-starter-netflix-eureka-client
       		
      		
      			
       
        org.springframework.cloud
       			
       
        spring-cloud-starter-openfeign
       		
      		
      			
       
        org.springframework.cloud
       			
       
        spring-cloud-starter-bus-amqp
       		
      		
      			
       
        org.springframework.boot
       			
       
        spring-boot-starter-test
       			
       
        test
       		
      				
      		
      			
       
        io.springfox
       			
       
        springfox-swagger-ui
       			
       
        2.4.0
       		
      		
      			
       
        io.springfox
       			
       
        springfox-swagger2
       			
       
        2.4.0
       		
      	
     	
     		
      			
       				
        
         org.springframework.cloud
        				
        
         spring-cloud-dependencies
        				
        
         ${spring-cloud.version}
        				
        
         pom
        				
        
         import
        			
       		
      	
     	
     		
      			
       				
        
         org.springframework.boot
        				
        
         spring-boot-maven-plugin
        			
       		
      	
     	
     		
      			
       
        spring-milestones
       			
       
        Spring Milestones
       			
       
        https://repo.spring.io/milestone
       		
      	
     
    复制代码

config-client的bootstrap.yml配置:

spring:  application:    name: user  cloud:    config:      discovery:        service-id: config        enabled: true      profile: proeureka:  client:    service-url:      defaultZone: http://localhost:9001/eureka/server:  port: 9005ribbon:  eureka:    enabled: true复制代码

4、测试

启动注册中心eureka

启动config server 访问localhost:9010/user-dev.yml监测是否启动成功

启动config client

在client项目中写一个测试类如下

测试类如下

@Component@RefreshScope@Data@ConfigurationProperties(prefix = "spring.redis")public class RedisConfig {    private String host;    private String port;}@RestController@RequestMapping("/test")public class ConfigController {    @Autowired    private RedisConfig redisConfig;    @RequestMapping("/print")    public String print() {        return "host:" +"\t" + redisConfig.getHost()+"====Port:"+redisConfig.getPort();    }}复制代码

页面访问http://localhost:9005/test/print,查看结果

修改gitee中的user-dev.yml文件

使用postman的post请求访问http://localhost:9010/actuator/bus-refresh

继续浏览器访问http://localhost:9005/test/print查看结果是否更新

自此config的刷新基本完成，最后一步在gitee中配置webhooks，每一次push修改之后都会自动的通知到各个客户端

4、配置仓库中的webhooks

点击gitee中的管理——》webhooks，填入外网访问的路径即可。
