参数 strutts2 s: iterate 标签
原标题:parameterizing struts2 s:iterate tag

我使用 struts2 “ s: iterate” 标签。 我的收藏名称在不断更改。 所以我要使用表达式来指定值。 根据 tld 表达式不允许在“ s: iterate” 标签中使用“ value ” 。

中存在保持数值变量的方法,而不是静态值。

     <s:iterator value="${param.listName}" status="status" > 
    </s:iterator>

类似上面的东西。 我想使用请求参数中的列表Name 来指定收藏的名称到循环标记 。

最佳回答

你的意思是像这样的:

<s:iterator var="reportHeader" value="%{#session.myList}" status="headerNumber" >
</s:iterator>

你的工作像一个魅力。

更新 :

myList in session.myList is a string 代表密钥。

因此,相应的行动守则将是

public String execute(){
  HttpSession session = ServletActionContext.getRequest().getSession();
  session.setAttribute("myList", new ArrayList<String>());
  return Action.SUCCESS;
}
