此處ServiceImpl,是myBatisPlus提供的一個基類。java
DispatchPageParam 是本身寫的一個查詢參數的封裝
/** * 基礎分頁參數 * @author shenjing * @date 2018/6/20 */ public class BasePageParam<T> { T obj; int pageIndex; int pageSize; public T getObj() { return obj; } public void setObj(T obj) { this.obj = obj; } public int getPageIndex() { return pageIndex; } public void setPageIndex(int pageIndex) { this.pageIndex = pageIndex; } public int getPageSize() { return pageSize; } public void setPageSize(int pageSize) { this.pageSize = pageSize; } }
實際上這個裏面什麼都沒有,只要繼承基類就能夠了app
