问题1如何在普通控件中接收action响应过来的值<br/>

普通链接<br/>
<a href="test1?username=<s:property value="username"/>">普通链接</a><br/>
<a href="test1?username=${username}">普通链接1</a><br/>
struts2链接<br/>
<s:a href="test1?username=%{username}">struts2链接</s:a><br/>
<s:url id="url" action="test1">
<s:param name="username">zhangsan</s:param>
</s:url>
<s:a href="%{url}">struts2链接1111</s:a>
</body>
