JAXB编组和解组CDATA [英] JAXB marshalling and unmarshalling CDATA

问题描述

我有一个要求，我有这样的XML

I have a requirement in which i have XML like this

<programs>
   <program>
      <name>test1</name>
      <instr><![CDATA[ some string ]]></instr>
   </program>
   <program>
      <name>test2</name> 
      <instr><![CDATA[ some string ]]></instr>
   </program>
</programs>

我的程序需要将其解组为JAXB，进行一些处理，最后再编组回xml。当我最终将JAXB对象编组为xml时，我得到没有CDATA前缀的纯文本。但为了保持xml完整，我需要使用CDATA前缀获取xml。似乎JAXB不直接支持这一点。有没有办法实现这个目标？

My program needs to unmarshal this to JAXB, do some processing and finally marshall back to xml. When I finally marshall the JAXB objects to xml, i get the as plain text without CDATA prefix. But to keep the xml intact I need to get the xml back with CDATA prefix. It seems JAXB doesnt suppor this directly. Is there a way to achieve this?

推荐答案

我也遇到了同样的问题，在查看时我发现了这篇文章。因为我用xjc生成我的bean，所以我不想在生成的代码中添加@XmlCData。

I've also had the same problem and while looking in SO I found this post. Since I'm generating my beans with xjc I did not want to add a @XmlCData in the generated code.

After looking a while for a good solution I finally found this post: http://javacoalface.blogspot.pt/2012/09/outputting-cdata-sections-with-jaxb.html

其中包含以下示例代码：

Which contains the following example code:

DocumentBuilderFactory docBuilderFactory = 
DocumentBuilderFactory.newInstance();
Document document = 
docBuilderFactory.newDocumentBuilder().newDocument();

// Marshall the feed object into the empty document.
jaxbMarshaller.marshal(jaxbObject, document);

// Transform the DOM to the output stream
// TransformerFactory is not thread-safe
StringWriter writer = new StringWriter();
TransformerFactory transformerFactory = 
TransformerFactory.newInstance();
Transformer nullTransformer = transformerFactory.newTransformer();
nullTransformer.setOutputProperty(OutputKeys.INDENT, "yes");
nullTransformer.setOutputProperty(
OutputKeys.CDATA_SECTION_ELEMENTS,
 "myElement myOtherElement");
nullTransformer.transform(new DOMSource(document),
 new StreamResult(writer));

它对我来说非常好。希望它能帮助其他人登陆这个页面，寻找同样的东西。

It works pretty fine for me. Hope it helps others that land in this page looking for the same thing I was.
