1,新建maven项目
pom文件中加入一下配置
<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.liu</groupId>
<artifactId>springBootHelloword</artifactId>
<version>0.0.1-SNAPSHOT</version>
<!-- 引入SpringBoot父类依赖 -->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.22.RELEASE</version>
</parent>
<dependencies>
<!-- springboot-web组件 springmvc+spring+mybatis -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
添加controller类
package com.liu.controller;
import java.util.HashMap;
import java.util.Map;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
//标识该接口全部返回json格式。
@RestController
public class HelloWorldController {
@RequestMapping("/index")
public String index() {
return "success";
}
@RequestMapping("/getMap")
public Map<String, Object> getMap() {
Map<String, Object> result = new HashMap<String, Object>();
result.put("errorCode", "200");
result.put("errorMsg", "成功..");
return result;
}
}
3,编写入口类
package com.liu;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@ComponentScan(basePackages = { "com.liu" })
@SpringBootApplication
public class App {
public static void main(String[] args) {
// 主函数运行springboot项目
SpringApplication.run(App.class, args);
}
}
4,运行main方法
访问
</dependencies>
</project>
