I am not aware of any option to make output use CDATA sections.

But why should you need to use CDATA sections? In XML CDATA is not semantically different from regular text section. It only exists as convenience thing for manual editing.

I ended up just putting in a placeholder, marshelling both objects, then manipulated the strings by hand... not clean not pretty but it worked.

blocks|key|733967|text|我们有一个类似的用例。我们需要用CDATA封装XML中的所有文本字段。这是我们需要实现的API的一个要求，我们在API中没有发言权。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|733968|为了解决这个问题，我们创建了@StaxMan建议的实现，即重写XMLOutputFactory和XMLStreamWriter，劫持writeCharacters()并调用writeCData()，这似乎非常有效。您可以在这里看到我们的确切代码(包名已更改)的要点：|offset|length|style|CODE|733969|https://gist.github.com/jbcpollak/8312151|733970|简而言之，我们创建了一个CDataXmlOutputFactoryImpl类，它创建了一个CDataXmlStreamWriter。不幸的是，我们需要包装目标类，而不是使用继承，因为这两个类都是最终的。而且，确切的编写者是可变的，所以包装是一个更安全的选择。|733971|在工厂中，除了用纯传递函数包装所有其他方法之外，对于每个createXMLStreamWriter()函数(有4)，您还需要如下所示：|733972|public+XMLStreamWriter+createXMLStreamWriter(Writer+w)+
++++throws+XMLStreamException
{

++++return+new+CDataXmlStreamWriter(f.createXMLStreamWriter(w));
}|code-block|syntax|javascript|733973|其中f是类中构造的OutputFactoryImpl。|733974|在CDataXmlStreamWriter中，除以下两种方法外，所有必需的函数都是w中方法的纯委托：|733975|public+void+writeCharacters(char[]+text,+int+start,+int+len)+
++++throws+XMLStreamException
{
++++w.writeCharacters(text,+start,+len);
}

//+All+this+code+just+to+override+this+method
public+void+writeCharacters(String+text)+throws+XMLStreamException
{

++++w.writeCData(text);
}|733976|这就是你所需要做的。就像这样使用你的新工厂：|733977|public+void+init()+{
++++XmlFactory+factory+=+new+XmlFactory(new+InputFactoryImpl(),
++++++++++++new+CDataXmlOutputFactoryImpl());
++++xmlMapper+=+new+XmlMapper(factory);
++++xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION,+true);
}|733978|完整的代码可以在上面的Gist中看到。|733979|如果您只需要包装在CDATA中的几个字段，我不确定这个解决方案是否有效。为此，我认为您需要修改ToXmlGenerator，以使它以某种方式了解您的模型(可能使用注释吗？)然后，在必要时，生成器会调用writeCData()。|733980|entityMap|0|LINK|mutability|MUTABLE|url^0|0|1U|H|2E|C|0|0|15|0|0|C|P|19|K|0|0|0|2|1|9|H|0|1|K|0|0|0|0|0|2S|C|0^^$0|@$1|2|3|4|5|6|7|1D|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|1E|8|@$D|1F|E|1G|F|G]|$D|1H|E|1I|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|1J|8|@]|9|@$D|1K|E|1L|1|1M]]|A|$]]|$1|J|3|K|5|6|7|1N|8|@$D|1O|E|1P|F|G]|$D|1Q|E|1R|F|G]]|9|@]|A|$]]|$1|L|3|M|5|6|7|1S|8|@]|9|@]|A|$]]|$1|N|3|O|5|P|7|1T|8|@]|9|@]|A|$Q|R]]|$1|S|3|T|5|6|7|1U|8|@$D|1V|E|1W|F|G]|$D|1X|E|1Y|F|G]]|9|@]|A|$]]|$1|U|3|V|5|6|7|1Z|8|@$D|20|E|21|F|G]]|9|@]|A|$]]|$1|W|3|X|5|P|7|22|8|@]|9|@]|A|$Q|R]]|$1|Y|3|Z|5|6|7|23|8|@]|9|@]|A|$]]|$1|10|3|11|5|P|7|24|8|@]|9|@]|A|$Q|R]]|$1|12|3|13|5|6|7|25|8|@]|9|@]|A|$]]|$1|14|3|15|5|6|7|26|8|@$D|27|E|28|F|G]]|9|@]|A|$]]|$1|16|3|-4|5|6|7|29|8|@]|9|@]|A|$]]]|17|$18|$5|19|1A|1B|A|$1C|I]]]]

We had a similar use case. We needed all text fields in our XML wrapped in CDATA. It was a requirement of an API we needed to implement and we had no say in the API. 

To solve the problem we created an implementation of @StaxMan's suggestion to override XMLOutputFactory and XMLStreamWriter to hijack <code>writeCharacters()</code> and call <code>writeCData()</code> instead, and this seems to work great. You can see a Gist of our exact code (with package names changed) here:

<a href="https://gist.github.com/jbcpollak/8312151" rel="nofollow">https://gist.github.com/jbcpollak/8312151</a>

In brief, we created a <code>CDataXmlOutputFactoryImpl</code> class which creates a <code>CDataXmlStreamWriter</code>. Unfortunately, rather than using inheritance we needed to wrap the target classes because both were final. Also, the exact writer to use is variable, so wrapping is a safer option.

In the factory, in addition to wrapping all the other methods with pure pass-through functions, you'll need something like this for each createXMLStreamWriter() function (there are 4):

<pre><code>public XMLStreamWriter createXMLStreamWriter(Writer w) 
 throws XMLStreamException
{

 return new CDataXmlStreamWriter(f.createXMLStreamWriter(w));
}
</code></pre>

where <code>f</code> is an <code>OutputFactoryImpl</code> constructed in the class.

In <code>CDataXmlStreamWriter</code> all the necessary functions are pure delegates for the methods in w, except for the two methods below:

<pre><code>public void writeCharacters(char[] text, int start, int len) 
 throws XMLStreamException
{
 w.writeCharacters(text, start, len);
}

// All this code just to override this method
public void writeCharacters(String text) throws XMLStreamException
{

 w.writeCData(text);
}
</code></pre>

Thats about all you need to do. Just use your new factory like this:

<pre><code>public void init() {
 XmlFactory factory = new XmlFactory(new InputFactoryImpl(),
 new CDataXmlOutputFactoryImpl());
 xmlMapper = new XmlMapper(factory);
 xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, true);
}
</code></pre>

The complete code can be see in the Gist above.

I'm not sure this solution would work if you only needed a few fields wrapped in CDATA. For that I think you would need to modify ToXmlGenerator, to make it aware of your model somehow (using annotations perhaps?) and then the generator would call <code>writeCData()</code> where necessary.

There is <code>@JacksonXmlCData</code> since 2.5. <a href="https://github.com/FasterXML/jackson-dataformat-xml" rel="noreferrer">https://github.com/FasterXML/jackson-dataformat-xml</a>:

<blockquote>
 <code>@JacksonXmlCData</code> allows specifying that the value of a property is to be serialized within a CData tag.
</blockquote>

I have the following java object

<pre><code>class MyXmlObject{
 @JsonProperty
 private InnerObject innerObject;
 @JsonProperty
 private String someOtherProperty;
}
</code></pre>

When I serialize this using 

<pre><code>public String getXmlObjectAsXML(MyXmlObject myXmlObject){
 JacksonXmlModule module = new JacksonXmlModule();

 module.setDefaultUseWrapper(false);
 XmlMapper mapper = new XmlMapper(module);

 mapper.configure(SerializationFeature.INDENT_OUTPUT, true);

 String response = "";

 response = mapper.writeValueAsString(myXmlObject);
 return response;
}
</code></pre>

I would like the InnerObject class to be wrapped in a CDATA tag.

What is the correct way to handle this scenario?
