dao层接口：
Java代码
代码如下：
package com.last999.im.news.dao;
import java.util.*;
import com.last999.im.news.entity.KindEntity;
import com.last999.im.news.web.PageTool;

public void update(KindEntity kindEntity);
public void delete(String uuid);
public void delete(KindEntity kindEntity);
public ListKindEntity findAll();
public KindEntity findKindEntityByName(String name);
public ListKindEntity getKindEntity(PageTool pageInfo);
public int getRows();
}
