Question

我正在尝试为我的字符串列表中的每个字符串生成一个链接。此链接将调用操作并传入参数（传入studentId的getStudentById操作）。我已经尝试了几种方法来通过搜索互联网来实现这一点，但是，没有任何运气。最近的尝试导致每个链接都有一个“www.com”的网址，我不知道它来自哪里。下面是一些文件，可以帮我弄清楚出了什么问题。

struts.xml中

Answer 1

而不是：

<s:iterator value="studentIds" status="status">
    <s:url action="getStudentById" includeParams="get" var="url">
        <s:param name="studentId"><s:property/></s:param>
    </s:url>
    <li>
        <s:a href="%{url}"><s:property/></s:a>
    </li>
</s:iterator>

我刚尝试了这个并且有效：

<s:iterator value="studentIds" status="status">
    <s:url action="getStudentById" includeParams="get" var="url">
        <s:param name="studentId"><s:property/></s:param>
    </s:url>
    <li>
        <s:a href="%{#url}"><s:property/></s:a>
    </li>
</s:iterator>

差异为％{url} vs％{＃url}

在s：中使用s：url：struts2中的a
