本文实例为大家分享了Android九宫格图片展示的具体代码，供大家参考，具体内容如下

推荐视频：尚硅谷Spring Data JPA视频教程，一学就会，百度一下就有。

后台代码：在DAO层继承Spring Data JPA的PagingAndSortingRepository接口实现的（实现方法主要在SbglServiceImpl.java类中）

前台表现：用kkpaper表现出来

实现效果：

1、实体类

package com.jinhetech.yogurt.sbgl.entity;import java.io.Serializable;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;import javax.persistence.PrimaryKeyJoinColumn;import javax.persistence.SequenceGenerator;import javax.persistence.Table;import org.hibernate.annotations.GenericGenerator;import org.springframework.cache.annotation.Cacheable;@Entity@Table(name="SYS_SBGL")@PrimaryKeyJoinColumn(name = "SBBM")@Cacheable(value = "baseCache")public class Sbgl implements Serializable{  private static final long serialVersionUID = -1423899016746755470L;  @Id  private String sbbm;    private String sbmc;  private String sblx;  private String sssx;  private String ssjd;    private String azsj;  private String azry;  private String sbzt;  private String sbjd;  private String sbwd;    private String wxlxr;  private String wxlxdh;  private String sbywxcs;  private String jzpylyz;  private String mqsbcyr;  private String bzsm;        //setter、getter方法省略  }

2、jsp页面，看最下面的分页组件（kkpaper）

resultMap集合是下面Controller中最后查询和分页后获得的所有数据信息，resultMap.resultList：resultList是Map集合的属性，里面存着<key,value>数据

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %><%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %><%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %><!doctype html><c:set var="ctx" value="${pageContext.request.contextPath}" scope="session"/><html><head>  <title>设备管理</title>  <!-- zTree需要的样式和js -->  <link rel="stylesheet" href="${ctx }/yogurtResource/assembly/ztree/css/zTreeStyle.css" rel="external nofollow" type="text/css">  <script type="text/javascript" src="${ctx }/yogurtResource/assembly/ztree/jquery.ztree.core-3.5.js"></script>  <script type="text/javascript" src="${ctx }/yogurtResource/assembly/ztree/jquery.ztree.excheck-3.5.js"></script>    <!-- 验证框架 -->  <script type="text/javascript" src="${ctx }/yogurtResource/assembly/yogurt/user/formValidate.js"></script>    <!-- 修改表单验证错误提示样式 -->  <style type="text/css">    .table-bordered-ul li{ margin:0 5px;

3、Controller（看红色字体下面那个处理方法）

package com.jinhetech.yogurt.sbgl.controller;import java.util.ArrayList;import java.util.HashMap;import java.util.LinkedHashSet;import java.util.List;import java.util.Map;import java.util.Set;import javax.annotation.Resource;import org.apache.shiro.authz.annotation.RequiresPermissions;import org.apache.shiro.authz.annotation.RequiresRoles;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.support.RedirectAttributes;import org.springframework.web.servlet.view.RedirectView;import com.jinhetech.yogurt.dictionary.crop.service.impl.CropServiceImpl;import com.jinhetech.yogurt.func.entity.Func;import com.jinhetech.yogurt.func.service.FuncService;import com.jinhetech.yogurt.menu.entity.Menu;import com.jinhetech.yogurt.menu.service.MenuService;import com.jinhetech.yogurt.menu.util.MenuUtil;import com.jinhetech.yogurt.organization.entity.OrgTable;import com.jinhetech.yogurt.organization.service.OrgService;import com.jinhetech.yogurt.organization.util.OrgUtil;import com.jinhetech.yogurt.role.entity.Role;import com.jinhetech.yogurt.role.service.RoleService;import com.jinhetech.yogurt.sbgl.dao.SbglDao;import com.jinhetech.yogurt.sbgl.entity.Sbgl;import com.jinhetech.yogurt.sbgl.service.SbglService;import com.jinhetech.yogurt.sbgl.util.SbglUtil;import com.jinhetech.yogurt.user.entity.User;import com.jinhetech.yogurt.user.entity.UserInfo;import com.jinhetech.yogurt.user.service.UserService;import com.jinhetech.yogurt.user.util.UserUtil;import com.jinhetech.yogurt.util.base.BaseController;import com.jinhetech.yogurt.util.base.Constants;import com.jinhetech.yogurt.util.common.TextUtils;import com.jinhetech.yogurt.util.common.UUIDHexGenerator;/** * 系统用户管理控制类 *  * @author Wang Hao * @version 1.0 2014-02-28 初版 */@Controller("sbglController")@RequestMapping("/sbgl")public class SbglController extends BaseController {//  @Resource(name = "sbglDao")//  private SbglDao sbglDao;

       Map<String, Object> resultMap = null;    // 查询表单或分页保持请求时 请求参数的接收    Map<String, String> serArgs = new HashMap<String, String>();    serArgs = SbglUtil.getSelArgsToMap(request);//这个类在下面给出        resultMap = sbglService.getUserBySearch(serArgs, "wxlxdh");        model.addAttribute("resultMap", resultMap);//    model.addAttribute("lst", lst);    return "sbgl/sbgl_list";  }  /**   * 新增设备信息列表(支持分页和多条件查询)。   *    * @author YangZhenghua 2014-5-28   * @throws Exception   */  @RequestMapping("sbgl_add_list")  @RequiresRoles("sbgl/sbgl_add_list")  public String getAddList(Model model) throws Exception {        System.out.println("aaa");

   String sblx=request.getParameter("sblx");    String sssx=request.getParameter("sssx");    String ssjd=request.getParameter("ssjd");    String azsj=request.getParameter("azsj");        String azry=request.getParameter("azry");    String sbzt=request.getParameter("sbzt");    String sbjd=request.getParameter("sbjd");    String sbwd=request.getParameter("sbwd");    String wxlxr=request.getParameter("wxlxr");        String wxlxdh=request.getParameter("wxlxdh");    String sbywxcs=request.getParameter("sbywxcs");    String jzpylyz=request.getParameter("jzpylyz");    String mqsbcyr=request.getParameter("mqsbcyr");    String bzsm=request.getParameter("bzsm");        sbgl.setSbbm(UUIDHexGenerator.generate());    sbgl.setSbmc(sbmc);    sbgl.setSblx(sblx);    sbgl.setSssx(sssx);    sbgl.setSsjd(ssjd);    sbgl.setAzsj(azsj);        sbgl.setAzry(azry);    sbgl.setSbzt(sbzt);    sbgl.setSbjd(sbjd);    sbgl.setSbwd(sbwd);    sbgl.setWxlxr(wxlxr);        sbgl.setWxlxdh(wxlxdh);    sbgl.setSbywxcs(sbywxcs);    sbgl.setJzpylyz(jzpylyz);    sbgl.setMqsbcyr(mqsbcyr);    sbgl.setBzsm(bzsm);    sbglService.save(sbgl);    return new ModelAndView(new RedirectView("sbgl_list"));  }}

3.2、SbglUtil.java

封装从前台传递过来的查询参数、前台传递过来的分页参数，都放到Map集合serArgs中

package com.jinhetech.yogurt.sbgl.util;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import java.util.Map.Entry;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpSession;import org.springframework.web.context.request.RequestContextHolder;import org.springframework.web.context.request.ServletRequestAttributes;import com.jinhetech.yogurt.organization.entity.OrgTable;import com.jinhetech.yogurt.report.entity.Report;import com.jinhetech.yogurt.role.entity.Role;import com.jinhetech.yogurt.user.entity.User;import com.jinhetech.yogurt.user.entity.UserInfo;import com.jinhetech.yogurt.util.common.JSONUtils;import com.jinhetech.yogurt.util.common.TextUtils;/** * 用户功能模块工具类。 *  * @author YangZhenghua * @version V1.0 2014-5-16 初版 *  */public class SbglUtil {  /**   * 封装从前台传递过来的查询参数。   *    * @author YangZhenghua   * @date 2014-6-26   */  public static Map<String, String> getSelArgsToMap(HttpServletRequest request) throws Exception {    Map<String, String> serArgs = new HashMap<String, String>();    String serSbmc = request.getParameter("serSbmc");    String serSblx = request.getParameter("serSblx");    String serSssx = request.getParameter("serSssx");    String serJdmc = request.getParameter("serJdmc");    String serSbzt = request.getParameter("serSbzt");        String pageNum = request.getParameter("pageNum") == null ? "1" : request.getParameter("pageNum");    String pageSize = request.getParameter("pageSize") == null ? "10" : request.getParameter("pageSize");    //serArgs.put("serUserName", java.net.URLDecoder.decode(serUserName == null ? "" : serUserName, "UTF-8"));    serArgs.put("serSbmc", serSbmc);    serArgs.put("serSblx", serSblx);    serArgs.put("serSssx", serSssx);    serArgs.put("serJdmc", serJdmc);    serArgs.put("serSbzt", serSbzt);        serArgs.put("pageNum", pageNum);    serArgs.put("pageSize", pageSize);    return serArgs;  }}

3.3、SbglService.java

package com.jinhetech.yogurt.sbgl.service;import java.util.List;import java.util.Map;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;import com.jinhetech.yogurt.sbgl.entity.Sbgl;public interface SbglService {  public List<Sbgl> getAll() throws Exception;    public Sbgl save(Sbgl sbgl) throws Exception;    public Map<String, Object> getUserBySearch(Map<String, String> serArgs, final String sortType) throws Exception;  }

3.4、SbglServiceImpl.java (根据前台传递来的查询参数进行查询，获得的结果数据放到Page objPage参数)

3.4.1、PageUtils.java(分页数据工具类)

package com.jinhetech.yogurt.util.common;import java.util.HashMap;import java.util.Map;import org.springframework.data.domain.Page;import org.springframework.data.domain.PageRequest;import org.springframework.data.domain.Sort;import org.springframework.data.domain.Sort.Direction;import com.jinhetech.yogurt.util.base.Constants;/** * 分页数据工具类。 *  * @author YangZhenghua * @version V1.0 2014-6-24 初版 *  */public class PageUtils {  /**   * 封装分页数据到Map中。   */  public static Map<String, Object> getPageMap(Page<?> objPage) {    Map<String, Object> resultMap = new HashMap<String, Object>();    resultMap.put(Constants.PAGE_RESULT_LIST, objPage.getContent()); // 数据集合    resultMap.put(Constants.PAGE_TOTAL_NUM, objPage.getTotalElements()); // 总记录数    resultMap.put(Constants.PAGE_TOTAL_PAGE, objPage.getTotalPages()); // 总页数    resultMap.put(Constants.PAGE_NUM, objPage.getNumber()); // 当前页码    resultMap.put(Constants.PAGE_SIZE, objPage.getSize()); // 每页显示数量    return resultMap;  }  /**   * 创建分页请求。   *    * @author YangZhenghua   * @date 2014-7-14   *    * @param pageNum 当前页   * @param pageSize 每页条数   * @param sortType 排序字段   * @param direction 排序方向   */  public static PageRequest buildPageRequest(int pageNum, int pageSize, String sortType, String direction) {    Sort sort = null;    if (!TextUtils.isNotBlank(sortType)) {      return new PageRequest(pageNum - 1, pageSize);    } else if (TextUtils.isNotBlank(direction)) {      if (Direction.ASC.equals(direction)) {        sort = new Sort(Direction.ASC, sortType);      } else {        sort = new Sort(Direction.DESC, sortType);      }      return new PageRequest(pageNum - 1, pageSize, sort);    } else {      sort = new Sort(Direction.ASC, sortType);      return new PageRequest(pageNum - 1, pageSize, sort);    }  }  /**   * 创建分页请求(该方法可以放到util类中).   */  public static PageRequest buildPageRequest(int pageNum, int pageSize, String sortType) {    return buildPageRequest(pageNum, pageSize, sortType, null);  }    /**   * 创建分页请求   *    * @author YangZhenghua   * @date 2014-11-12   *    * @param pageNum   * @param pageSize   * @param sort   * @return   */  public static PageRequest buildPageRequest(int pageNum, int pageSize, Sort sort) {    return new PageRequest(pageNum - 1, pageSize, sort);  }  /**   * 创建分页请求(该方法可以放到util类中).   */  public static PageRequest buildPageRequest(int pageNum, int pageSize) {    return buildPageRequest(pageNum, pageSize, null, null);  }}

4、DAO（SbglDao.java）,对，只需要继承Spring Data JPA的PagingAndSortingRepository接口，Controller中调用其findAll()方法

package com.jinhetech.yogurt.sbgl.dao;import org.springframework.data.jpa.repository.JpaSpecificationExecutor;import org.springframework.data.repository.CrudRepository;import org.springframework.data.repository.PagingAndSortingRepository;import org.springframework.stereotype.Repository;import com.jinhetech.yogurt.sbgl.entity.Sbgl;import com.jinhetech.yogurt.user.entity.UserInfo;@Repository("sbglDao")public interface SbglDao extends PagingAndSortingRepository<Sbgl, String>, JpaSpecificationExecutor<Sbgl> {    }
