如何将 JSP 变量转换为 Struts2 变量？

我尝试过以下方法:

<%=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

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

Answer 1

<s:push>必须包含 <s:property>标签。还有

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

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