springcloud版本: 【Finchley 版】

分布式配置中心  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2NzYyNjc3_size_16_color_FFFFFF_t_70]  
集中管理配置文件-提供了集中化的外部配置支持,配置服务器为各个微服务的环境提供了一个中心化的外部配置  
动态配置  
springcloud Config分为客户端和服务端(分布式配置中心,是一个独立的微服务应用)  
推荐使用git管理版本信息

启动类

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

--------------------

<table> 
 <tbody> 
  <tr> 
   <td align="left"><b><font>客户端配置</font></b></td> 
  </tr> 
 </tbody> 
</table>

1.  客户端配置上传到github  
    [https://github.com/ai1045152332/springcloud-config/blob/master/cloud-config-client.yml][https_github.com_ai1045152332_springcloud-config_blob_master_cloud-config-client.yml]
2.  创建config-client项目

2.1 pom文件

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-client</artifactId>
    </dependency>

2.2 bootstrap.yml系统级资源配置项,优先级高

spring:
      cloud:
        config:
          name: cloud-config-client # github上配置文件名
          profile: dev # 本次访问的配置项
          label: master
          uri: http://localhost:3344 # 连接server

application.yml (是用户级)

spring:
      application:
        name: cloud-config-client

1.  接口

/** * 描述: * 配置客户端rest访问配置 * * @author zhaojianyu * @create 2018-12-21 8:49 PM */
    @RestController
    public class ConfigClientRest { 
        @Value("${spring.application.name}")
        private String applicationName;
    
        @Value("${eureka.client.service-url.defaultZone}")
        private String eurekaServer;
    
        @Value("${server.port}")
        private String port;
    
        @RequestMapping("/config")
        public String getConfig(){ 
        	//通过3344 server获取配置信息
            return "application:"+applicationName+"<br/>"+
                    "eurekaServer:"+eurekaServer+"<br/>"+
                    "port:"+port+"<br/>";
        }
    }

启动类无特殊改动  
4. 两种访问
