【SpringCloud】SpringBoot2.1.7+springcloud config refresh 404

现象

今天尝试做SpringBoot2微服务 整合SpringCloud Config配置，Config Server 和Config Client，服务端配置从Git获取，Client端通过自定义接口方法获取，此时修改git配置文件，Server端能够获取新的配置信息，Client端无法刷新，所以要做client端的配置刷新

根据网上一通操作无法起效，书籍上是SpringBoot1.x ，client端项目resources/bootstrap.yml配置如下

spring:
  application:
    name: microservice-config-client
  cloud:
    config:
      profile: prod # 配置服务中的{profile}
      label: master # 对应git中的分支，默认为master
      uri: http://localhost:8888/  # 配置中心的地址
server:
  port: 8801
management: 
  security:
    enabled: false

client 启动Applicaiton类

package com.itheima.springcloud;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author lifei
 * @date 2019/8/12 - 16:39
 */
@RefreshScope
@SpringBootApplication
@RestController
public class ConfigClientApplicaiton {

    @Value("${clientParam}")
    private String clientParam;

    @RequestMapping("/clientParam")
    public String getParam() {
        return this.clientParam;
    }


    @RequestMapping("/hello")
    public String hello() {
        return "hello world!";
    }

    public static void main(String[] args) {
        SpringApplication.run(ConfigClientApplicaiton.class, args);
    }

}

 

通过调用 post请求 http://localhost:8801/refresh 报404错误找不到

 

原因

Spring boot 2.0的改动较大，/bus/refresh全部整合到actuator里面了，变成了/actuator/refresh,所以之前1.x的management.security.enabled全部失效，不适用于2.0 

 

完整解决方案

Server端pom.xml配置

        UTF-8
        UTF-8
        1.8
        
        
        
    
    
        
            org.springframework.cloud
            spring-cloud-config-server
            2.0.1.RELEASE
        
    

Server端Applicaiton

package com.itheima.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;

/**
 * @author lifei
 * @date 2019/8/8 - 15:30
 */
@EnableConfigServer
@SpringBootApplication
public class ConfigServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ConfigServerApplication.class, args);
    }
}

Sever端application.yml

spring:
  application:
    name: microservice-config-server
  #  profiles:
  #    active: native   # 使用本地文件系统的存储方式来保存配置信息
  cloud:
    config:
      server:
        git: # 使用git的方式
          uri: https://gitee.com/xxx/microservice-building-config.git

server:
  port: 8888

#Spring boot 2.0的改动较大，/bus/refresh全部整合到actuator里面了，变成了/actuator/bus-refresh,所以之前1.x的management.security.enabled全部失效，不适用于2.0
#  注意：config-server和config-client的配置都需要加上
management:
  endpoints:
    web:
      exposure:
        include: refresh

Client端pom.xml配置

 microservice-config-client

    
        
            org.springframework.cloud
            spring-cloud-starter-config
            2.0.1.RELEASE
        

        
            org.springframework.boot
            spring-boot-starter-web
            2.1.7.RELEASE
        

        
            org.springframework.boot
            spring-boot-starter-actuator
            2.1.7.RELEASE
        
    

Client端Applicaiton 需要加注解@RefreshScope

package com.itheima.springcloud;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author lifei
 * @date 2019/8/12 - 16:39
 */
@RefreshScope
@SpringBootApplication
@RestController
public class ConfigClientApplicaiton {

    @Value("${clientParam}")
    private String clientParam;

    @RequestMapping("/clientParam")
    public String getParam() {
        return this.clientParam;
    }


    @RequestMapping("/hello")
    public String hello() {
        return "hello world!";
    }

    public static void main(String[] args) {
        SpringApplication.run(ConfigClientApplicaiton.class, args);
    }

}

Client端bootstrap.yml配置

spring:
  application:
    name: microservice-config-client
  cloud:
    config:
      profile: prod # 配置服务中的{profile}
      label: master # 对应git中的分支，默认为master
      uri: http://localhost:8888/  # 配置中心的地址
server:
  port: 8801
#management: #过时
#  security:
#    enabled: false


management:
  endpoints:
    web:
      exposure:
        include: refresh

 

最后通过client端的Post请求http://localhost:8801/actuator/refresh刷新，再查看配置发现配置已经更新

curl -v -X POST "http://localhost:8888/actuator/refresh"
