DWZ是实用的国产JQuery UI框架，个人感觉比较好用。
他和服务器端主要通过Ajax方式交互，数据格式为json。
服务器响应数据代码示例：
{
"statusCode":"200",
"message":"操作成功",
"navTabId":"actvtyList",
"rel":"",
"callbackType":"closeCurrent",
"forwardUrl":""
}
statusCode是返回码， 200表示成功， 300表示服务器错误，301表示请求超时。
message为返回信息，dwz中会显示在一个在浏览器顶部中间位置的对话框中。
rel 没研究，想研究的可以参考dwz的官方文档。
navTabId是tab id，表示刷新指定的tab。
callbackType是回调方式，closeCurrent表示关闭当前的tab或者dialog
forwardUrl 为转向url，表示当前tab或者dialog跳转到指定的url。
首先为DWZ定义java数据模型
package com.mytest.domain.dwz;public class DwzAjaxResult {private String statusCode;private String message;private String navTabId;private String callbackType;private String forwardUrl;public DwzAjaxResult(String statusCode, String message, String navTabId,String callbackType, String forwardUrl) {this.statusCode = statusCode;this.message = message;this.navTabId = navTabId;this.callbackType = callbackType;this.forwardUrl = forwardUrl;}//getters & setters}public class DwzPager implements Serializable {private static final long serialVersionUID = 1L;private String status;private String keywords;private Integer pageNum = 1;private Integer numPerPage = 20;private Integer pageTotal = 0;private Integer total = 0;public String getStatus() {return status;}public void setStatus(String status) {this.status = status;}public String getKeywords() {return keywords;}public void setKeywords(String keywords) {this.keywords = keywords;}public Integer getPageNum() {if(pageNum == null || pageNum < 1) pageNum = 1;if(pageNum > getPageTotal()) pageNum = getPageTotal();return pageNum;}public void setPageNum(Integer pageNum) {this.pageNum = pageNum;}public Integer getNumPerPage() {return numPerPage;}public void setNumPerPage(Integer numPerPage) {if(numPerPage!=null)this.numPerPage = numPerPage;}public Integer getPageTotal() {if(total == null) return 1;pageTotal = (total + numPerPage – 1) / numPerPage;return pageTotal;}public void setPageTotal(Integer pageTotal) {this.pageTotal = pageTotal;}public Integer getTotal() {return total;}public void setTotal(Integer total) {this.total = total;}}
然后是服务器struts代码，其中printDwzJsonResult()方法是将对象转换成dwz数据格式并写入servletoutputstream。
public class ActivityAction extends BaseActionSupport {private ActivityService activityService;private List<Activity> activityList;private Activity activity;private String pk;//主键值，以#连接（用于组合主键）private DwzPager pager = new DwzPager();//需要定义下面4个变量是dwz的pagerForm提交的分页参数private String status = "";private String keywords = "";private Integer pageNum = 1;private Integer numPerPage = 20;public ActivityAction(){activityService = new ActivityServiceImpl();}public void activityAdd() throws Exception{DwzAjaxResult resultBean;if(activityService.addActivity(activity)){setSessionPageNum(pageNum);//将当前页码保存到session，避免操作完后刷新列表时自动跳转到第1页的尴尬resultBean = new DwzAjaxResult("200","保存成功","","forward",request.getContextPath()+"/admin/actvty/add.jsp");}else{resultBean = new DwzAjaxResult("300","保存失败","","","");}printDwzJsonResult(resultBean);}public void activityUpdate() throws Exception{DwzAjaxResult resultBean;if(activityService.updateActivity(activity)){setSessionPageNum(pageNum);//将当前页码保存到session，避免操作完后刷新列表时自动跳转到第1页的尴尬resultBean = new DwzAjaxResult("200","修改成功","actvtyList","closeCurrent","");}else{resultBean = new DwzAjaxResult("300","修改失败","","","");}printDwzJsonResult(resultBean);}public String activityEdit() throws Exception{String[] prikeys = pk.split("#");//拆分主键值，这里简单地取第一个主键，需要完善逻辑activity = activityService.findActivity(Integer.parseInt(prikeys[0]));return SUCCESS;}public void activityDelete() throws Exception{DwzAjaxResult resultBean;String[] prikeys = pk.split("#");activity = activityService.findActivity(Integer.parseInt(prikeys[0]));if(activity!=null && activityService.deleteActivity(activity)){setSessionPageNum(pageNum);resultBean = new DwzAjaxResult("200","删除成功","actvtyList","","");}else{resultBean = new DwzAjaxResult("300","删除失败","","","");}printDwzJsonResult(resultBean);}public void activitySearch() throws Exception{pager.setPageNum(1);setSessionPageNum(1);DwzAjaxResult resultBean = new DwzAjaxResult("200","结果已过滤","actvtyList","","");//不操作业务逻辑，直接刷新actvtyList列表printDwzJsonResult(resultBean);}public String activityList() throws Exception{int total = 0;if(activity != null) total = activityService.totalFuzzyActivitys(activity);else total = activityService.totalActivitys();pageNum = getSessionPageNum()!=null?getSessionPageNum():pageNum;pager.setTotal(total);pager.setStatus(status);pager.setKeywords(keywords);pager.setPageNum(pageNum);pager.setNumPerPage(numPerPage==null?pager.getNumPerPage():numPerPage);if(activity != null) activityList = activityService.getFuzzyActivitys(activity, pager.getPageNum(), pager.getNumPerPage());else activityList = activityService.getActivitys(pager.getPageNum(), pager.getNumPerPage());removeSessionPageNum(); //重置session中的pageNumreturn SUCCESS;}public List<Activity> getActivityList(){return activityList;}public void setPk(String pk){this.pk = pk;}public DwzPager getPager() {return pager;}public void setActivity(Activity activity){this.activity = activity;}public Activity getActivity(){return activity;}public void setStatus(String status) {this.status = status;}public void setKeywords(String keywords) {this.keywords = keywords;}public void setPageNum(Integer pageNum) {this.pageNum = pageNum;}public Integer getPageNum() {return this.pageNum;}public void setNumPerPage(Integer numPerPage) {this.numPerPage = numPerPage;}}struts2配置，大部分action都是ajax请求，所以都没配置处理结果。
每个人心中，都会有一个古镇情怀，流水江南，烟笼人家。
