使用jsp：include和json-taglib的HTML输出 [英] HTML output with jsp:include and json-taglib

问题描述

我使用jsp：include内部的 json-taglib 的json：property元素。与此相关的问题是，来自包含的JSP页面的所有HTML元素在某些时候被剥离并且只保留纯文本。我已经删除了所有换行符，所以结果必须是有效的JSON数据。

如何获得由json-taglib返回的完整HTML？

以下是显示情况的摘录。

 <％@ page language =java％ > 
 <％@ page pageEncoding =UTF-8％> 
 <％@ page contentType =text / html; charset = UTF-8％> 
 
 <％@ taglib uri =http://www.atg.com/taglibs/jsonprefix =json％> 
 
< json：object> 
< json：property name =idvalue =$ {element.id}/> 
< json：属性名称=htmlescapeXml =false> 
< jsp：include page =/ templates / generate-component.jsp> 
< jsp：param name =element_idvalue =$ {element.id}/> 
< / jsp：include> 
< / json：property> 
< / json：object> 
  

解决方案

一个解决方案是将jsp：include包装在< c：out> 标记和（mis）使用body-as-default-value，如下所示：

 < c：out value =$ {null}> 
< jsp：include ...> 
< jsp：param ... /> 
< / jsp：include> 
< / c：out> 
  

然而，在包含的JSP本身使用jsp：include的情况下，这不起作用。 / p>

I'm using jsp:include inside json-taglib's json:property element. The problem with this is that all HTML elements from included JSP page gets stripped at some point and only plain text remains. I have already stripped all newlines so the result shoud be valid JSON data.

How do I get full HTML returned by json-taglib?

Below is a snippet demonstrating the situation.

<%@ page language="java" %>
<%@ page pageEncoding="UTF-8" %>
<%@ page contentType="text/html; charset=UTF-8" %>

<%@ taglib uri="http://www.atg.com/taglibs/json" prefix="json" %>

<json:object>
  <json:property name="id" value="${element.id}" />
  <json:property name="html" escapeXml="false">
    <jsp:include page="/templates/generate-component.jsp">
      <jsp:param name="element_id" value="${element.id}" />
    </jsp:include>
  </json:property>
</json:object>

解决方案

One solution is to wrap the jsp:include in <c:out> tag and (mis)use the body-as-default-value, like so:

<c:out value="${null}">
  <jsp:include ...>
    <jsp:param ... />
  </jsp:include>
</c:out>

However, this won't work in a situation where the included JSP itself uses jsp:include.
