1.打开idea,创建项目
2.只需等待加载即可
3.项目结构
4.pool.xml代码

5.com.example.helloword 包下的HelloWordApplication,是程序启动的入口,代码如下,并且不需要做任何修改
package com.example.helloword;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class HelloWordApplication {
public static void main(String[] args) {
SpringApplication.run(HelloWordApplication.class, args);
}
}
6.在HelloWordApplication文件中右键,然后选择run HelloWordApplication,等到控制台输入如下内容则说明项目启动成功
7.8080是本项目的端口号,可以在配置文件中修改,在地址栏输入localhost:8080,出来如下内容:
8.接下来我们写第一个helloWord,在com.example.helloword 包下新建一个controller包,然后新建Hello.java文件,内容如下:
package com.example.helloword.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class Hello {
@RequestMapping("/hello")
public String TestController(){
return "Hello Word";
}
}
9.然后重启项目,在地址栏内输入http://localhost:8080/hello,出现以下的页面,则第一个简单的springboot项目构建成功
