1.创建springboot项目。

2.pom.xml

<?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.didispace</groupId>
       <artifactId>config-client</artifactId>
       <version>1.0.0</version>
       <packaging>jar</packaging>
    
       <name>config-client</name>
       <description>Spring Cloud project</description>
    
       <parent>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-parent</artifactId>
          <version>1.3.5.RELEASE</version>
          <relativePath/> 
       </parent>
    
       <properties>
          <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
          <java.version>1.8</java.version>
       </properties>
    
       <dependencies>
    
          <dependency>

          <dependency>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-starter-web</artifactId>
          </dependency>
    
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-config-client</artifactId>
            </dependency>
    
          
             
             
          
    
          <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-starter-eureka</artifactId>
          </dependency>
    
       </dependencies>
    
       <dependencyManagement>
          <dependencies>

       <build>
          <plugins>

             </plugin>
          </plugins>
       </build>
    
    </project>

3.bootstrap.properties （这个配置文件先于application.properties 加载。）

# 这里的名字千万不能乱取 这里就是文件名的前缀
    # 这里没有注意 坑了我好久 ！！！
    spring.application.name=cxb
    spring.cloud.config.profile=test
    spring.cloud.config.label=master
    spring.cloud.config.uri=http://localhost:7001/
    # 这里和URI 两种选一种都行
    #spring.cloud.config.discovery.service-id=config-server
    
    server.port=7002
    
    eureka.client.serviceUrl.defaultZone=http://localhost:1111/eureka/
    
    # 读取权限
    spring.cloud.config.discovery.enabled=true

import org.springframework.beans.factory.annotation.Value;
    import org.springframework.cloud.context.config.annotation.RefreshScope;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RefreshScope
    @RestController
    class TestController {
        
        // 这里建议加上默认值，不然可能加载不到该from的时候会报错
        @Value("${from: DefaultValue}")
        private String from;
    
        @RequestMapping("/from")
        public String from() {
            return "hello " + this.from;
        }
    
    }

5.启动类

import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
    
    @SpringBootApplication
    @EnableDiscoveryClient
    public class Application {
    
       public static void main(String[] args) {
          new SpringApplicationBuilder(Application.class).web(true).run(args);
       }
    
    }

6.访问[http://localhost:1111/][http_localhost_1111]

[http://192.168.8.1:7002/from][http_192.168.8.1_7002_from]

这样就获取了远程仓库的配置文件的值。

[http_localhost_1111]: http://localhost:1111/
