我是靠谱客的博主重要故事，最近开发中收集的这篇文章主要介绍学习Spring Boot 途中遇到的Bug即解解决方法（一），觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1. 遇到创建之后，无法正常启动的问题可能是 Idea创建的Spring Boot项目的版本问题。

当版本是 2.2.0.RELEASE时，会遇到下面的异常，

解决方式：将pom.xml文件中 parent 标签中 spring boot 的版本修改为 2.1.9.RELEASE

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<!--<version>2.2.0.RELEASE</version>-->
该版本我遇到又启动问题
<version>2.1.9.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
