前端查询表格数据的时候，会分别调用 `search` 和 `count` 服务。 如果重写了 `search` 服务，修改了查询条件，就需要把 `count` 服务也一并重写。 ```java public List<Model> search(Filter filter, List<String> properties, Integer limit, Integer offset, String order) { } public Long count(Filter filter) { } ``` 其实这就是继承带来的问题，所以如果你继承某个父类，一定要对这个父类的接口实现非常清楚。 具体可以参考 [effective java 第18条](https://github.com/clxering/Effective-Java-3rd-edition-Chinese-English-bilingual/blob/dev/Chapter-4/Chapter-4-Item-18-Favor-composition-over-inheritance.md)
