这里我们使用 Intellij IDEA 来新建一个 Spring Boot 项目。
创建完成后的工程目录结构如下：
│ .gitignore
│ pom.xml
│
│
└─src
├─main
│ ├─java
│ │ └─com
│ │ └─funtl
│ │ └─hello
│ │ └─spring
│ │ └─boot
│ │ HelloSpringBootApplication.java
│ │
│ └─resources
│ │ application.properties
│ │
│ ├─static
│ └─templates
└─test
└─java
└─com
└─funtl
└─hello
└─spring
└─boot

spring-boot-starter-web：包含了 spring-boot-starter 还自动帮我们开启了 Web 支持我们创建一个 Controller 来演示一下 Spring Boot 的神奇功能
package com.snaek.hello.spring.boot.controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; @RestController public class HelloController { @RequestMapping(value = "", method = RequestMethod.GET) public String sayHi() { return "Hello Spring Boot"; } }
启动 HelloSpringBootApplication 的 main() 方法，浏览器访问 http://localhost:8080 可以看到：
Hello Spring Boot
