**1. 创建Maven Project**

**2. 配置pom.xml**

<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">
      <modelVersion>4.0.0</modelVersion>
      <groupId>com.springboot</groupId>
      <artifactId>SpringBootTest</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      
      <parent>
      	<groupId>org.springframework.boot</groupId>
      	<artifactId>spring-boot-starter-parent</artifactId>
      	<version>1.4.1.RELEASE</version>
      </parent>
      
      <properties>
      	<java.version>1.8</java.version>
      </properties>
      
      <dependencies>
      	<dependency>
      		<groupId>org.springframework.boot</groupId>
      		<artifactId>spring-boot-starter-web</artifactId>
      	</dependency>
      </dependencies>
    </project>

**3. 编写application.properties**  
在src/main/resources下，定义端口以及前缀后缀：(在src/main/resources下)，定义端口以及前缀后缀：

server.port=80
    #\u914D\u7F6E\u524D\u7F00
    spring.mvc.view.prefix=/WEB-INF/jsp/
    #\u914D\u7F6E\u540E\u7F00
    spring.mvc.view.suffix=.jsp

**4. 新建控制类HelloController.java和测试类App.java**  
SpringBoot里面没有servlet的概念，只需要建一个java类即可，写在src/main/java下：  
HelloController.java：

package springboot.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController//与@Controller区别：无需别的配置就可以return字符串，而不是jsp页面
    public class HelloController {
    	@RequestMapping("/Hello")
    	public String Hello(){
    		return "Hello SpringBoot";
    	}
    }

App.java：

package springboot;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication//标记为springboot应用
    public class App {
    	public static void main(String[] args) {
    		//启动应用
    		SpringApplication.run(App.class,args);
    	}
    }

**5. 测试**  
选中App.java 的main函数，右键 run with springboot  
打开网页http://localhost:80/Hello
