我有两套

set1  contains("A","B","C","D") elements
set2  contains("E","F","D","G") elements

我想将set1的每个元素与set2的每个元素进行比较,并使用Struts2标签显示匹配的元素.

解决方法:

请尝试以下代码：

<s:iterator var="val1" value="set1">
 <s:iterator var="val2" value="set2">
  <s:if test="#val1 == #val2">
   <s:property /><br>
  </s:if>
 </s:iterator>
</s:iterator>
