如何在struts中使用url编码参数? [英] How to encode a parameter with a url in struts?

问题描述

页面上会显示书籍列表.当用户单击一本书时，会打开其详细信息页面.现在的问题是我需要使用详细信息页面 url 对每本书的 id 进行编码.

A list of books is displayed on the page. When a user clicks a book, its detail page is opened. Now the problem is that I need to encode each book's id with the detail page url.

详细信息页面的链接是/loadDetailForm.do.如果图书的 id=23，则链接应显示为/loadDetailForm.do?id=23.

The link to detail page is /loadDetailForm.do. If a book has id=23, the link should appear as /loadDetailForm.do?id=23.

我在这里粘贴代码:

<logic:notEmpty name="BrowseForm" property="books">
                <logic:iterate id="book" property="books" name="BrowseForm" type="com.nms.bks.app1.domain.Book">
                        <p><html:link action="/loadDetailForm" styleClass="btn_blue"><bean:write name="book" property="title"/></html:link></p>
                </logic:iterate>
            </logic:notEmpty>

谢谢

推荐答案

您可以指定一个参数映射，struts 标记将这些参数附加到 url.

You can specify a map of parameters which the struts tag will append to the url.

参见 http://struts.apache.org/1.2.x/userGuide/struts-html.html#link

查看 paramId、paramName 和 paramProperty 属性.

Look at the paramId, paramName and paramProperty attributes.

<html:link action="/loadDetailForm" 
       styleClass="btn_blue" 
       paramId="id" 
       paramName="book" 
       paramProperty="id">
          <bean:write name="book" property="title"/>
</html:link>

另一种方法是使用 JSTL 标记库

An alternative would be to use the JSTL tag library

<c:url value="expression" context="expression"
    var="name" scope="scope">
  <c:param name="param1" value="${thing.id}"/>
  ...
</c:url>
