Struts2界面和action之间数据的传递，ValueStack在其中的作用

一，从界面到后台的数据传递

1，form表单传递

 1 <form action="prizeList" method="post" id="searchForm">
 2             <label>奖品编号</label>
 3             <div class="telInput" style="margin:0px 5px 5px 0px;">
 4                 <input type="text" name="prizeId" id="prizeId" value="<s:property value="prizeId"/>"/>
 5             </div>
 6             <label>奖品名称</label>
 7             <div class="telInput" style="margin:0px 5px 5px 0px;">
 8                 <input type="text" name="prizeName" id="prizeName" value="<s:property value="prizeName"/>"/>
 9             </div>
10             <label>奖品类型</label>
11             <div class="telInput" sstyle="margin:0px 5px 5px 0px;">
12                 <input type="text" name="prizeType" id="prizeType" value="<s:property value="prizeType"/>"/>
13             </div>
14             </div>
15             <div class="sel-top proInput">
16             <label>中奖概率</label>
17             <div class="telInput" style="margin:0px 5px 5px 0px;">
18                 <input type="text" name="prizeChance" id="prizeChance" value="<s:property value="prizeChance"/>"/>
19             </div>
20             <label>流量面额</label>
21             <div class="telInput" style="margin:0px 5px 5px 0px;">
22                 <input type="text" name="prizeNotes" id="prizeNotes" value="<s:property value="prizeNotes"/>"/>
23             </div>
24         </form>

2，url传递

1 /woserver/backstage/prizeList.action?prizeId=${prizeId}&prizeName=${prizeName}&prizeType=${prizeType}&prizeChance=${prizeChance}&prizeNotes=${prizeNotes}

3，ajax参数传递

 1 $.ajax({
 2          async : false,
 3          type : "POST",
 4          data : {"prizeId":"0000"},
 5          url : "deletePrize",
 6         dataType: "json",
 7         success: function(rdata){
 8             alert(rdata);
 9         },
10         error : function(rdata){    
11           
12         }
13      });

struts.xml中配置

 1  <struts>
 2       <package name="backstage" namespace="/backstage" extends="struts-default"> 
 3           <action name="prizeList" class="mine.action.PrizeListAction">
 4               <result name="success">/backstage/prizeList.jsp</result>
 5            </action> 
 6             <action name="deletePrize" class="mine.action.PrizeListAction">
 7               <result name="json">/backstage/prizeList.jsp</result>
 8          </action> 
 9       </package>
10 
11  </struts>

100         JSONArray prizes=BaseDao.query(CustomDataSource.DATASOURCE2.getDataSource(), getPaginationSql(), null);
101 
102         prizeList=new ArrayList<Prize>();

109                 prize.setPrizeId(prizeObject.getString("item0"));
110                 prize.setPrizeName(prizeObject.getString("item1"));
111                 prize.setPrizeType(prizeObject.getString("item2"));

118             }
119             
120         }
121         return SUCCESS;

123 }

第一步：

把请求参数封装在ActionContext

String
