项目积累demo-01

1 搭建Spring-Boot项目

　　在这里我使用intellij新建spring boot工程；

点击next;

输入Group以及artifact之后。点击next.之后点击web.接着finish就ok了

测试案列，证明spring boot工程搭建完毕；

·1）依赖的pom.xml

测试demo(该类是程序自动生成的)

package com.gosaint.spring.boot.blog.initiallizrstart;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@EnableAutoConfiguration
@SpringBootApplication
public class InitiallizrStartApplication {

    @RequestMapping("/hello")
    @ResponseBody
    String home() {
        return "Hello World!";
    }
    public static void main(String[] args) {
        SpringApplication.run(InitiallizrStartApplication.class, args);
    }
}

启动main()方法；如下所示

访问localhost:8080/hello:

好了，就此一个Spring-Boot的web工程已经启动了！
