Springboot项目解决Error starting ApplicationContext. To display the conditions report re-run your applic

问题描述：

        启动Springboot项目时爆出“Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.”

        问题描述内容是：配置DataSource失败：未指定“URL”属性，也无法对任何嵌入式数据盎司进行配置

        原因是：未能确定合适的驱动程序类

 报错部分的源代码：

package com.example.summer_task.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;@Controller@RequestMapping("/staff")public class StaffController {    @GetMapping("/hello")    @ResponseBody    public String hello(){        return "hello";    }}

解决方式：

修改了pom.xml文件

修改如下：
