篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了maven+spring boot搭建简单微服务相关的知识，希望对你有一定的参考价值。
项目需要使用spring boot，所以自学了几天，仅提供给新手，请根据文档查看…该项目仅是测试项目，并不完善和严谨，只实现了需要使用的基本功能。写该博客一是希望能够帮助刚学习的新人，二是加深自己的印象，如果忘了也可以再看看，有些片段是从其他博客学习来的，如有问题希望能提出来，由衷的表示感谢。
主要开发环境：jdk：1.8； maven：3.3；tomcat：8等。
涉及技术：spring boot、springMVC、maven、JdbcTemplate、json、HttpClient等。
推荐博客：http://blog.csdn.net/jsyxcjw/article/details/46763639，这里有大家需要的一些理论知识，请结合参考，我就写一下简单的过程和贴代码了。
1、目录结构
- spring boot服务中心
- 调用者
2、数据库结构
3、服务中心的配置文件

HttpServletResponse response, ModelMap modelMap, String id)
if (StringUtils.isNotBlank(id))
return userInfoMapper.getUserInfoById(Integer.parseInt(id));

- spring boot启动访问入口
package com.beyond;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.bind.annotation.RestController;
@RestController
@ComponentScan
@EnableAutoConfiguration
public class Application
//启动spring boot的入口
public static void main(String[] args) throws Exception
SpringApplication.run(Application.class, args);
5、启动spring boot
此时启动Application 的main方法，控制台显示：
默认端口号是8080，此时就可以启动spring boot了，可通过http://localhost:8080/user/getUserInfoList访问数据，结果如下：
也可以通过maven打包成jar访问，进入项目路径
打包成功后进入你写spring boot的入口类的项目中的target中执行jar
显示如下则表示执行成功，可访问
也可以将jar直接上传到Linux系统中（需配置java环境），直接执行jar
