• 我还给你找了一篇非常好的博客，你可以看看是否有帮助，链接：springboot项目里面，连接数据库配置里面& ，这个符号进行报错，如何解决
• 您还可以看一下 甘智昌老师的基于springboot的统一返回值和异常处理课程中的 创建springboot项目小节, 巩固相关知识点
  
• 除此之外, 这篇博客: 如何创建一个springboot项目中的 五、运行springboot项目并验证。 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:
  

  1⃣️ 新建一个类。名叫HelloController, 代码如下：

  package com.example.demo;
  import org.springframework.web.bind.annotation.RequestMapping;
  import org.springframework.web.bind.annotation.RestController;
  
  /**
   * 测试springboot
   *
   * @author: sky
   * @create: 2018-11-18
   */
  @RestController
  public class HelloController {
  
      @RequestMapping("/hello")
      public String hello() {
          return "Hello Spring Boot!";
      }
  }
  

  2⃣️ 使用idea启动Springboot工程，找到Springboot的运行累，然后右键点击run
  注意⚠️：springboot是内置tomcat的，我所以我们运行的时候不需要配置tomcat就可以。
  

  注意⚠️：
  如若启动时报错Failed to configure a DataSource: ‘url‘ attribute is not specified and no embedded
  请查看：

  解决springboot启动报错Failed to configure a DataSource: ‘url‘ attribute is not specified and no embedded

  项目跑起来以后就会显示如下信息。说明项目启动成功。
  

  3⃣️ 在浏览器中测试。
  此时我们已经能看懂tomcat在运行8080端口，
  

  我们在chrome中试着通过localhost:8080来访问我们的项目。下图说明运行正常。
