**背景：基于[springcloud（十）][springcloud]继续**

### 分布式配置中心客户端 ###

**1. 创建****spring-cloud-config-client工程，pom.xml文件依赖**

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
    
        <groupId>com.zsx</groupId>
        <artifactId>spring-cloud-config-client</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <packaging>jar</packaging>
    
        <name>spring-cloud-config-client</name>
        <description>Spring Cloud Config Client project</description>
    
        <parent>
            <groupId>com.zsx</groupId>
            <artifactId>spring-cloud-customize-dependencies</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <relativePath>../spring-cloud-customize-dependencies/pom.xml</relativePath>
        </parent>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-config-client</artifactId>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        <mainClass>com.zsx.ConfigClientApplication</mainClass>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </project>

**2. bootstrap.yml文件**

# 配置服务器的默认端口为 8888
    # 如果修改了默认端口，则客户端项目就不能在 application.yml 或 application.properties 中配置
    # spring.cloud.config.uri，必须在 bootstrap.yml 或是 bootstrap.properties 中配置
    # 原因是 bootstrap 开头的配置文件会被优先加载和配置
    server:
      port: 8090
    spring:
      application:
        name: spring-cloud-config-client
      cloud:
        config:
          # 配置服务中心的网址
          uri: http://localhost:8088
          # 配置文件名称的前缀
          name: config-client
          # 配置仓库的分支
          label: master
          # 配置文件的环境标识
          profile: dev
    eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:8081/eureka/

**3.  api接口类**

package com.zsx.api.controller;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.http.HttpStatus;
    import org.springframework.http.ResponseEntity;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    @RequestMapping("/api/config/client")
    public class ConfigClientTestController {
    
        @Value("${customize.port}")
        private String port;
    
        @GetMapping("/{message}")
        public ResponseEntity get(@PathVariable("message") String message) {
            return new ResponseEntity(String.format("The message content is : %s, Service port is : %s", message, port), HttpStatus.OK);
        }
    }

**4. 引导类**

package com.zsx;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    
    @SpringBootApplication
    @EnableDiscoveryClient
    public class ConfigClientApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(ConfigClientApplication.class, args);
        }
    }

**5. 修改git仓库中config-client-dev.yml文件内容为**

customize:
      port: 8089

**6. 依次启动注册服务中心、配置中心服务端、配置服务客户端**

**7.  查看请求 [http://localhost:8088/config-client-dev.yml][http_localhost_8088_config-client-dev.yml]**

**8. 查看请求[http://localhost:8090/api/config/client/hello][http_localhost_8090_api_config_client_hello]**

**到此配置服务客户端完成**
