你的eclipse需要先安装

## [Spring Tool Suite™][Spring Tool Suite] ##

### 第一种方法（不建议，之所以贴上是因为探索的过程） ###

首先新建Maven工程

![813478-20171225165237822-2089407280.png][]

勾选第一个按钮，第三个是选择working set ，你可以不选

下一步，配置工程信息，注意打包为jar

![813478-20171225165734103-1942969917.png][]

打开pom.xml文件，添加spring-boot依赖

![复制代码][copycode.gif]

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>1.5.9.RELEASE</version>
        </parent>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>

新建文件src/main/hello/HelloController.java

![复制代码][copycode.gif]

package hello;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class HelloController {
    
        @RequestMapping("/")
        public String hello(){
            return "Greetings from Spring Boot!";
        }
    }

![复制代码][copycode.gif]

新建src/main/hello/Application.java

![复制代码][copycode.gif]

package hello;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class Application {
    
        public static void main(String[] args) {
            // http://localhost:8080/
            SpringApplication.run(Application.class, args);
        }
    }

![复制代码][copycode.gif]

运行Application

出现一堆：

![813478-20171225170744400-1687705477.png][]

访问localhost:8080/

![813478-20171225171113978-1120059475.png][]

### 第二种方法（推荐） ###

File-》new-》other

![813478-20171225221827790-863788967.png][]

选择starter项目

![813478-20171225221908447-1958874088.png][]

下一步

![813478-20171225221934634-1403421188.png][]

下一步

![813478-20171225222017759-1519536548.png][]

勾选Web，Finish。可以看到项目结构与我们自己建的Maven有些不一样。

新建一个Controller

![复制代码][copycode.gif]

package com.example.demo;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class HelloController {
    
        @RequestMapping("/")
        public String hello(){
            return "Welcome to start SpringBoot!";
        }
    }

![复制代码][copycode.gif]

运行

![813478-20171225222336603-290187765.png][]

运行结果

比起原来的Spring项目，构建过程简单多了
