1,根据官网例子，使用maven构建heloword
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> <parent> <groupId>springBootTest</groupId> <artifactId>springBootTest</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>springBootWeb</artifactId> <packaging>war</packaging> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>1.5.4.RELEASE</version> </dependency> </dependencies> </project> 2.helloController.java 代码 /** * Copyright EXPRESS PAY 2017, Inc. All rights reserved. */ /** * */ package springBootWeb; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; /** * <p> * TODO。 * </p> * * @author lujia * @version 1.0 * @date 2017年7月11日 */ @Controller @EnableAutoConfiguration public class HelloController { @RequestMapping("/") @ResponseBody public String home(){ return "hello word!"; } public static void main(String[] args) { SpringApplication.run(HelloController.class, args); } } 3.直接运行，springboot会直接启动一个tomcat，开启8080端口的访问，
