警告: Hessian/Burlap: 'com.github.pagehelper.Page' is an unknown class in WebappClassLoader

So, the entire solution is to add dependent PageHelper and Mybatis in the web of the pom.xml.

 

1     <dependency>
2      <groupId>com.github.pagehelper</groupId>
3      <artifactId>pagehelper</artifactId>
4     </dependency>
5 
6     <dependency>
7      <groupId>org.mybatis</groupId>
8      <artifactId>mybatis</artifactId>
9     </dependency>
