生成文件

以下以下载excel文件为例，如有其它需要可自定义实现类继承相应springmvc提供的试图接口即可。

如生成Excel则继承AbstractExcelView，生成PDF则继承AbstractPdfView。

java代码：

1 /*

2 * 导出用户信息到EXCEL

3 *

4 * @return

5 */

6 @RequestMapping(value = "/excel") 7 public ModelAndView exportExcel() { 8 ModelAndView mv = this.getModelAndView(); 9 PageData pd = new PageData(); 10 pd = this.getPageData(); 11 try { 12 13 // 检索条件=== 14 String USERNAME = pd.getString("USERNAME"); 15 if (null != USERNAME && !"".equals(USERNAME)) { 16 USERNAME = USERNAME.trim(); 17 pd.put("USERNAME", USERNAME); 18 } 19 String lastLoginStart = pd.getString("lastLoginStart"); 20 String lastLoginEnd = pd.getString("lastLoginEnd"); 21 if (lastLoginStart != null && !"".equals(lastLoginStart)) { 22 lastLoginStart = lastLoginStart + " 00:00:00"; 23 pd.put("lastLoginStart", lastLoginStart); 24 } 25 if (lastLoginEnd != null && !"".equals(lastLoginEnd)) { 26 lastLoginEnd = lastLoginEnd + " 00:00:00"; 27 pd.put("lastLoginEnd", lastLoginEnd); 28 } 29 // 检索条件=== 30 31 MapdataMap = new HashMap(); 32 Listtitles = new ArrayList(); 33 34 titles.add("用户名"); // 1 35 titles.add("编号"); // 2 36 titles.add("姓名"); // 3 37 titles.add("职位"); // 4 38 titles.add("手机"); // 5 39 titles.add("邮箱"); // 6 40 titles.add("最近登录"); // 7 41 titles.add("上次登录IP"); // 8 42 43 dataMap.put("titles", titles); 44 45 ListuserList = userService.listAllUser(pd); 46 ListvarList = new ArrayList(); 47 for (int i = 0; i < userList.size(); i++) { 48 PageData vpd = new PageData(); 49 vpd.put("var1", userList.get(i).getString("USERNAME")); // 1 50 vpd.put("var2", userList.get(i).getString("NUMBER")); // 2 51 vpd.put("var3", userList.get(i).getString("NAME")); // 3 52 vpd.put("var4", userList.get(i).getString("ROLE_NAME")); // 4 53 vpd.put("var5", userList.get(i).getString("PHONE")); // 5 54 vpd.put("var6", userList.get(i).getString("EMAIL")); // 6 55 vpd.put("var7", userList.get(i).getString("LAST_LOGIN")); // 7 56 vpd.put("var8", userList.get(i).getString("IP")); // 8 57 varList.add(vpd); 58 } 59 60 dataMap.put("varList", varList); 61 62 ObjectExcelView erv = new ObjectExcelView(); // 执行excel操作 63 64 mv = new ModelAndView(erv, dataMap); 65 } catch (Exception e) { 66 logger.error(e.toString(), e); 67 } 68 return mv; 69 }
