由于返回的list不仅包含对象  我还想返回一些字符串  所以就写一个继承类来实现！

package test;

import cn.ljzblog.ljz.model.PicCriticismTemp;

public class SuperPicCriticims extends PicCriticismTemp {
      private int totalPage;
      private int currentPage;
      private String picLoginTime;
  	private String picDetail;
  	private String pictureName;
  	
	public int getTotalPage() {
		return totalPage;
	}
	public void setTotalPage(int totalPage) {
		this.totalPage = totalPage;
	}
	public int getCurrentPage() {
		return currentPage;
	}
	public void setCurrentPage(int currentPage) {
		this.currentPage = currentPage;
	}
	public String getPicLoginTime() {
		return picLoginTime;
	}
	public void setPicLoginTime(String picLoginTime) {
		this.picLoginTime = picLoginTime;
	}
	public String getPicDetail() {
		return picDetail;
	}
	public void setPicDetail(String picDetail) {
		this.picDetail = picDetail;
	}
	public String getPictureName() {
		return pictureName;
	}
	public void setPictureName(String pictureName) {
		this.pictureName = pictureName;
	}
      
}
