我是靠谱客的博主仁爱万宝路，这篇文章主要介绍关于使用Mybatis-Plus中返回值类型与继承Service中泛型类型不一致的问题controllerserviceImpl，现在分享给大家，希望可以做个参考。

今天遇到了一个问题，就是我使用开发框架自动生成了有关于数据库表中的数据（全部属性）的controller，service，Impl之类的，都是有关于数据库的表的实体类，但是我要传输的条件，和我要返回的条件不是数据库的那个实体类
需求：一个对应数据库中所有属性的实体类，一个输入的实体类，一个输出的实体类，完成分页查询

controller

public R getBigOthNppReportPageSimple(Page page, BigOthNppReport bigOthNppReport) {
IPage<BigOthNppReportSimple> bigOthNppReportPageSimple = bigOthNppReportService.getBigOthNppReportPageSimple(page, bigOthNppReport);
return R.ok(bigOthNppReportPageSimple);
}
