标准的html链接

<a href="../../processLinks.do">Link using HTML &lt;a&gt; tag</a>

请求某个页面，.do的action也可以认为是页面

<html:link page="/processLinks.do">Link using page attribute</html:link>

请求以linksAction作为actionId的action

 <html:link action="linksAction">Link using action attribute</html:link>

请求以linksAction作为actionId的action，并且停留在test锚上

 <html:link action="linksAction" anchor="test">Link to an anchor</html:link>

含有参数的链接

硬编码参数的链接

<html:link action="linksAction?color=blue">Hardcoded parameter</html:link>

动态参数，参数名为color，值为上下文的变量值

 <html:link action="linksAction" paramId="color" paramName="myColor">Dynamic parameter</html:link>

动态参数，参数名为msg，参数值为上下文的变量的属性

 <html:link action="linksAction" paramId="msg" paramName="testBean" paramProperty="stringValue">Dynamic parameter from a bean property</html:link>

动态参数，参数的名和值存储在上下文的map里

<html:link action="linksAction" name="parms">Multiple dynamic parameters from a Map</html:link>

动态参数，参数名和值用<html:para>构造出来

<html:link action="linksAction" name="parms">

      Dynamic parameters from &lt;html:param&gt;

      <html:param name="buybefore" value="Tomorrow" />

      <html:param name="shippedfrom" value="New York" />

</html:link>

打印链接的描述，参数属性的含义与html:link一致

<html:rewrite action="linksAction" paramId="color" paramName="myColor" />

 <html:rewrite action="linksAction" paramId="msg" paramName="testBean" paramProperty="stringValue" />

 <html:rewrite action="linksAction" name="parms" />

    <html:rewrite action="linksAction">

      <html:param name="buybefore" value="Tomorrow" />

      <html:param name="shippedfrom" value="New York" />

    </html:rewrite>

<html:rewrite action="linksAction" />
