1.警告实例
警告: Hessian/Burlap: ‘com.github.pagehelper.Page’ is an unknown class in WebappClassLoader
context:
delegate: false
repositories:
----------> Parent Classloader:
ClassRealm[plugin>org.apache.tomcat.maven:tomcat7-maven-plugin:2.2, parent: sun.misc.Launcher$AppClassLoader@ec6b00]
:
java.lang.ClassNotFoundException: com.github.pagehelper.Page
三月 25, 2018 4:46:58 下午 com.alibaba.com.caucho.hessian.io.SerializerFactory getDeserializer

2在表现层只引入pageHelper依赖

com.github.pagehelper
pagehelper
–>
后，出现了以下错误：

3.经分析得知，mybatis的分页pagehelper插件依赖于mybatis的相关jar包，因此终极的解决办法是在表现层同时加入分页pagehelper的jar包和mybatis的相关jar包，如下

<dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId>
</dependency>
<dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId>
</dependency>
<dependency><groupId>com.github.miemiedev</groupId><artifactId>mybatis-paginator</artifactId>
</dependency>
<dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper</artifactId>
</dependency>
