使用IDEA创建一个Spring Boot项目过程如下

 填写合适的项目信息

启动类

package com.zln.sb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Created by sherry on 17/2/20.
 */

@SpringBootApplication
public class SbApplication {
    public static void main(String[] args) {
        SpringApplication.run(SbApplication.class, args);
    }
}




HelloWorld控制器

package com.zln.sb.c;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by sherry on 17/2/20.
 */
@RestController
public class HelloWorld {

    /**
     * 日志
     */
    private Logger logger = LoggerFactory.getLogger(HelloWorld.class);

    @RequestMapping("/")
    public String helloworld(){
        return "Hello World 呵呵";
    }

}




启动SbApplication后，直接在浏览器输入 http://localhost:8080，出现

 

 

 

HelloWorld创建完毕
