1.背景

有时候引入包有冲突,比如在Maven项目中的不同模块多次重复引入等

这里遇到的问题是重复映入了如下包:

<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.0-RELEASE</version>
</dependency>

导致启动报错如下:

.....
.....
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

2.问题排查步骤

步骤一:利用idea提供的工具查看依赖

 步骤二:点击进去,找到最左左边红色的箭头,然后点击进去,找到那个引用,删除尝试即可

完美
