1. 新建一个Maven Web项目。
2. 配置pom.xml文件。
<?xml version="1.0" encoding="UTF-8"?>
<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.yws710.springboot</groupId>
<artifactId>demo1</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.4.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
</project>
3. 编写控制器类
package com.yws710.springboot.demo1.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
/**
* Created by Administrator on 2017/7/19.
*/
@Controller
public class HelloController {
@ResponseBody
@RequestMapping("/hello")
public String hello() {
return "Hello, Spring Boot!";
}
}
4. 编写启动类
package com.yws710.springboot.demo1;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Created by Administrator on 2017/7/19.
*/
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
5. 启动项目。只需要运行上面代码的main方法，运行成功，控制台输出如下：
"D:/Program Files/Java/jdk1.7.0_67/bin/java" ... . ____ _ __ _ _ /// / ___'_ __ _ _(_)_ __ __ _ / / / / ( ( )/___ | '_ | '_| | '_ // _` | / / / / /// ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_/__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v1.5.4.RELEASE) 省略部分信息 2017-07-20 00:16:44.849 INFO 5388 --- [ main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 8080 (http) 2017-07-20 00:16:44.858 INFO 5388 --- [ main] com.yws710.springboot.demo1.App : Started App in 5.835 seconds (JVM running for 6.364)
6. 在浏览器中输入 http://localhost:8080/hello，显示结果如下：
好了，一个最简单的Web项目完成了。没有写任何的配置文件，也没有任何的xml文件（这里完全可以把web.xml文件删掉）。
