使用IDEA新建一个spring boot项目

通过上面步骤完成了基础项目的创建，如上图所示，Spring Boot的基础结构共三个文件（具体路径根据用户生成项目时填写的Group所有差异）：

src/main/java下的程序入口：Chapter1Application

src/main/resources下的配置文件：application.properties

src/test/下的测试入口：Chapter1ApplicationTests

生成的Chapter1Application和Chapter1ApplicationTests类都可以直接运行来启动当前创建的项目，由于目前该项目未配合任何数据访问或Web模块，程序会在加载完Spring之后结束运行。

引入web模块当前的pom.xml内容如下，仅引入了两个模块：

spring-boot-starter：核心模块，包括自动配置支持、日志和YAML

spring-boot-starter-test：测试模块，包括JUnit、Hamcrest、Mockito

引入Web模块，需添加spring-boot-starter-web模块

详细代码参考pom.xml

编写HelloWorld服务

详细代码参考HelloWorldController.java

package com.morris.web;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by lian.chen on 2017/6/12.
 */
@RestController
public class HelloWorldController {

    @RequestMapping("hello")
    public String hello() {
        return "hello world";
    }
}

运行Chapter1Application中的main方法，启动项目
浏览器输入 http://localhost:8080/hello 显示 hello world
