工具类

PageBean

package org.hp.util;import lombok.Data;import java.util.List;@Data
public class PageBean<T>{private int totalPage;  //总页数private int totalCount; //总条数private int page;       //当前页数private int limit;      //每页记录数private List<T> list;   //数据集public PageBean(int totalPage, int totalCount, int page, int limit, List<T> list) {this.totalPage = totalPage;this.totalCount = totalCount;this.page = page;this.limit = limit;this.list = list;}public PageBean() {}
}

Layui

package org.hp.util;import lombok.Data;import java.util.HashMap;
import java.util.List;
import java.util.Map;@Data
public class Layui extends HashMap<String, Object> {private int code;private String msg;private int count;private Object data;public static Layui select(int count,Object data){Layui layui=new Layui();layui.put("code",0);layui.put("msg","");layui.put("count",count);layui.put("data",data);return layui;}public static Layui select(Object data){Layui layui=new Layui();layui.put("code",0);layui.put("msg","");layui.put("data",data);return layui;}public static Layui update(int code){Layui layui=new Layui();layui.put("code", code);layui.put("msg","");return layui;}
}

正式开发

}

Service实现

package org.hp.service;import org.hp.util.PageBean;import java.util.List;
import java.util.Map;public interface AService {List<Map> query(String sql,Object...objs);boolean renow(String sql,Object...objs);PageBean<Map> pageFind(int page, int limit , String sql, String...obj);
}//Service实现的Impl
DBHelper dbHelper=new DBHelper();
@Overridepublic PageBean<Map> pageFind(int page, int limit, String sql, String... obj) {return dbHelper.pageList(page,limit,sql);}package org.hp.service.impl;import org.hp.service.AService;
import org.hp.util.DBHelper;
import org.hp.util.PageBean;import java.util.List;
import java.util.Map;public class AServiceImpl implements AService {DBHelper dbHelper=new DBHelper();@Overridepublic List<Map> query(String sql, Object... objs) {return dbHelper.query(sql,objs);}@Overridepublic boolean renow(String sql, Object... objs) {if(dbHelper.renow(sql,objs)>0)return true;elsereturn false;}@Overridepublic PageBean<Map> pageFind(int page, int limit, String sql, String... obj) {return dbHelper.pageList(page,limit,sql);}
}

dao实现(这里我封装到工具类里了)
