如何将JSP变量转换为Struts2变量?

How do I convert a JSP variable to a Struts2 variable?

我尝试了以下操作:

<%=scoredDocument%>
<s:push value="scoredDocument"/>
<s:push value="#scoredDocument"/>
<s:push value="%{scoredDocument}"/>
<s:push value="${scoredDocument}"/>
<s:push value="#page.scoredDocument"/>
<s:push value="%{#page.scoredDocument}"/>

<display:column title="Study Code" sortable="true">
    <s:property value="id"/>

最常见的错误是

起因:标记"push"，字段"value":您必须指定一个值以压入堆栈.示例:人员-[未知位置]

Caused by: tag 'push', field 'value': You must specify a value to push on the stack. Example: person - [unknown location]

推荐答案

<s:push>必须包含<s:property>标记.还有

<s:push value="#attr.scoredDocument">
    <display:column title="Study Code" sortable="true">
        <s:property value="id"/>
    </display:column>
</s:push>

#attr? WTF Struts?甚至没有记录！ https://struts.apache.org/release/2.0.x/docs /jsp.html

#attr? WTF Struts? It's not even documented! https://struts.apache.org/release/2.0.x/docs/jsp.html
