IDEA搭建SpringBoot项目环境

一、磨唧磨唧

我记得我之前有写，然而翻遍所有记录实际没有，所以是否存在另一个时空？

配置文件比较牛，是可以在Controller直接返回jsp页面，Controller中return字串自带后缀.jsp

关于这样配置需要返回值的ajax怎么传值，用的是out.print就行。利大于弊。

二、具体步骤

1，idea首页查一下Configure-Settings，本地maven配置路径

2，Create New Project

3，我选择手动配置，默认下一步

4，起个项目名，finish

5，配置pom.xml

 配置语句：

6，pom配置语句写好后，刷新一下

7，逐级把这些文件建出

8，项目配置在Web上

在idea中点file-之后根据图片操作

点开那个小文件标志，逐级找到webapp

之后全点ok完成，webapp出现蓝点证明项目配置在web上很成功

9，在resources下建一个mapping文件夹，两个配置文件

 application.yml

10，在java下建包，建一个主类

package com.demo;

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

@SpringBootApplication
public class MyMain {
    //主方法
    public static void main(String[] args) {
        SpringApplication.run(MyMain.class,args);//MyMain是当前类名
    }

}

11，在com.demo下建Controller包，建一个Controller类

简单写个sing测试

12，上一步返回的路径是指定在pages下，我们建一个jsp

三、使用运行

鼠标放在主类里面，右键运行

 当控制台打印日志，最后显示运行秒数之后就可以在浏览器访问了。

浏览器访问方式为：http://127.0.0.1:端口号/方法value名。
