1. 创建Maven工程

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">

3. application.yml

server:
  port: 9082

logging:
  level:
    com.netflix.discovery: 'OFF'
    org.springframework.cloud: 'DEBUG'

4. bootstrap.yml

spring:
  cloud:
    config:
      uri: http://localhost:9099
      name: uploads                   #使用uploads配置
      profile: ${config.profile:dev}  #如果启动时未添加config.profile参数，则加载dev配置

5. 启动类

package com.pasenger.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Created by Pasenger on 2017/4/15.
 */

@SpringBootApplication
public class ConfigClientApplication {

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

6. REST API

package com.pasenger.springcloud;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Pasenger on 2017/4/15.
 */

@RestController
@RequestMapping(value = "/upload")
public class UploadsController {

    @Value("${upload.dir}")
    private String uploadDir;

    @Value("${upload.suffix}")
    private String uploadSuffix;


    @RequestMapping(value = "/dir", method = RequestMethod.GET)
    public String getUploadDirApi(){
        return uploadDir;
    }

    @RequestMapping(value = "/suffix", method = RequestMethod.GET)
    public String getUploadSuffixApi(){
        return uploadSuffix;
    }

    public String getUploadDir() {
        return uploadDir;
    }

    public void setUploadDir(String uploadDir) {
        this.uploadDir = uploadDir;
    }

    public String getUploadSuffix() {
        return uploadSuffix;
    }

    public void setUploadSuffix(String uploadSuffix) {
        this.uploadSuffix = uploadSuffix;
    }
}

其中的uploadDir和uploadSuffix既从config-server获取的配置。

7. 测试

curl http://localhost:9082/upload/dir
/var/log

curl http://localhost:9082/upload/suffix
docx
