pagehelper报错的问题解决

运行以前写的一个练习的项目时报错，pagehelper报错信息如下：com.github.pagehelper.PageHelper cannot be cast to org.apache.ibatis.plugin.Interceptor

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in file [C:\Users\guojing\Desktop\soa\e3-manager\e3-manager-service\target\classes\spring\applicationContext-dao.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse config resource: class path resource [mybatis/SqlMapConfig.xml]; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration.

解决办法：

代码片段:

注意引入的pom文件内容：

		5.0.1
		1.0

分析：

PageHelper5.0版本pagehelper继承了PageMethod和实现了Dialect

而报错却说无法将PageHelper转为Interceptor，所以查看源码包的Interceptor
