mybatis-plus-boot-starter 引入后启动报错 Error creating bean with name 'meetingAction': Unsatisfied dependency expressed through field 'userMapper';
自己写项目的时候碰到一个需求，要用到分页，
mybatis-plus-boot-starter
pagehelper-spring-boot-starter
了解到上面的jar都提供了分页，我用的是第一个
pom文件如下：
<!--Spring boot整合Mybatis之通用mapper-->
<dependency>
<groupId>tk.mybatis</groupId>
<artifactId>mapper-spring-boot-starter</artifactId>
<version>2.0.4</version>
<exclusions>
<exclusion>
<artifactId>persistence-api</artifactId>
<groupId>javax.persistence</groupId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.4.2</version>
</dependency>
启动报错如下：

然后把mapper-spring-boot-starter 注释掉即可！
