本文已参与「新人创作礼」活动，一起开启掘金创作之路。
项目架构图：
1.新建一个新的项目
2.选择对应的配置
3.选择Spring Web
4.写好项目名称以及存放的位置
5.把上面选中的五个文件选中并进行删除
6.最后只剩下有用的文件即可（和之前的spring文件一样)
- 刚刚创建以后文件不可用，那么我们需要自动设置一下
8.把java,resources文件设置一下编辑
9.添加Maven依赖
10.添加pom.xml相关依赖

11.设置setting配置
12.点击导入，我们发现相关依赖(Maven)已经导入了
13.如果配置出现错误，那可以设置一下import的JDK
最后发现已经不报错啦！！！
14.下面开始运行一下
15.写一下Controller层，再写一个HelloController类
HelloController.java:
localhost:8080/hello/hello
package com.kuang.Controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@RequestMapping("/hello")
public class HelloController {
@GetMapping("/hello")
@ResponseBody
public String hello(){
return "hello";
}
}
然后重启一下服务器，我们尝试访问一下localhost:8080/hello/hello:
编辑
发现上述访问成功啦！
以上博客到此结束啦！
