SSH s:iterator 配合 s:if 使用

上伪代码。希望实现动态选中 动态生成的 select 的某一项。 status你可以看做 具有 code 和 name 属性的一个 类。
action :
int status_code = 2;
List<status> statusListData = { {code = 0, name = "已失效"},{code = 1, name = "进行中"},{code = 2, name = "已完成"} };
jsp:
<select value = "<s:property value = 'status_code' />">
<s:iterator value = "statusListData">
/*
<s:if test = "code == status_code" >
<option value = "<s:property value = ‘code’ />" selected> <s:property value = 'name'> </option>
</s:if>
<s:else>
<option value = "<s:property value = ‘code’ />"> <s:property value = 'name'> </option>
</s:else>
*/
</s:iterator>

Answer 1

int statusCode = 2;

public int getStatusCode() {
return statusCode;
}

java.util.Map<Integer, String> statusListData=new java.util.HashMap<Integer, String>();

public java.util.Map<Integer, String> getStatusListData() {
return statusListData;
}

<select name="sstatus">
<s:iterator value="statusListData" id="st">
<s:if test="#st.key==statusCode" >
<option value="<s:property value='#st.key'/>" selected><s:property value='#st.value'/></option>
</s:if>
<s:else>
<option value="<s:property value='#st.key'/>"> <s:property value='#st.value'/> </option>
</s:else>
</s:iterator>
</select>
