com.github.pagehelper.PageHelper cannot be cast to org.apache.ibatis.plugin.Interceptor
<dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>4.0.0</version> </dependency>
升级到
<dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>5.1.11</version> </dependency>
pageHelper升级后，报错：

解决办法：
<plugins> <!-- com.github.pagehelper为PageHelper类所在包名 --> <plugin interceptor="com.github.pagehelper.PageHelper"> <property name="dialect" value="mysql"/>
改为：
<plugins> <!-- com.github.pagehelper为PageHelper类所在包名 --> <plugin interceptor="com.github.pagehelper.PageInterceptor"> <property name="dialect" value="com.github.pagehelper.PageHelper"/>
