如何在Spring + JSP中创建超链接 [英] How to create hyperlink in Spring + JSP

问题描述

在Spring + JSP中创建超链接的正确方法是什么？必须有一个比在< a href =...> 标记中编码更好的方法。以一个显示人物的页面为例。该URL为 people.htm 。相应的控制器从数据库中获取人员并执行可选的列排序。 JSP可能如下所示：

What's the proper way to create a hyperlink in Spring+JSP? There must be a better way than just coding in the <a href="..."> tag. Take for example a page that displays people. The URL is people.htm. The corresponding controller gets people from the database and performs optional column sorting. The JSP might look like:

<table>
<tr>
  <td><a href="people.htm?sort=name">Name</a></td>
  <td><a href="people.htm?sort=age">Age</a></td>
  <td><a href="people.htm?sort=address">Address</a></td>
</tr>
...

这似乎很糟糕，因为URL 人。 htm 在JSP中是硬编码的。应该有一种方法让Spring使用 servlet.xml 中定义的URL自动构建< a> 标记。

This seems bad as the URL people.htm is hardcoded in the JSP. There should be a way to have Spring automatically build the <a> tag using the URL defined in servlet.xml.

编辑：也许我应该使用Spring表单。

Edit: Maybe I should be using a Spring form.

推荐答案

唯一想到的是JSTL标准标签< c：url> 。 例如：

The only thing that comes to mind is the JSTL standard tag <c:url>. For example:

<c:url var="thisURL" value="homer.jsp">
  <c:param name="iq" value="${homer.iq}"/>
  <c:param name="checkAgainst" value="marge simpson"/>
</c:url>
<a href="<c:out value="${thisURL}"/>">Next</a>

现在这不会让你获得servlet映射等，但什么都不会。这不是你可以用编程方式做的事情（毕竟，servlet可以并且通常映射到一系列URL）。但这将为你逃避。

Now this won't get you servlet mapping or the like but nothing will. It's not something you could really do programmatically (after all, a servlet can and usually does map to a range of URLs). But this will take care of escaping for you.
