如何将 Struts2 变量转换为常规 JSP <% 变量？

<s:iterator var="item" value="results">
   <jsp:useBean id="item" type="com.google.appengine.api.search.ScoredDocument"/>

Caused by: java.lang.InstantiationException: bean item not found within scope

Answer 1

这有效：<s:set var="item" value="%{item}"/>

<s:iterator var="item" value="results">
    <s:set var="item" value="%{item}"/>
    <jsp:useBean id="item" type="com.google.appengine.api.search.ScoredDocument" />
    <%= item %><br/>
