解决springboot在使⽤pagehelper-spring-boot-starter。。。spring boot 已经使⽤了⾃动分页插件 pagehelper-spring-boot-starter ，但是在⾃定义mybatis 的时候，并不能⽣效，原因就是,pagehelper ，进⾏拦截处理后，没有调⽤之后的，直接返回了⾃⼰的执⾏结果，导致之后的没有调⽤.
下⾯贴出我的代码，可以执⾏
添加⽂件:
MyBatisConfig.java
需要注意，添加了
@AutoConfigureAfter(PageHelperAutoConfiguration.class)
springboot aoppackage com.fig;
