我可以强制JAXB不要转换“进入& quot;，例如，当编组到XML？ [英] Can I force JAXB not to convert " into ", for example, when marshalling to XML?

问题描述

我有一个使用JAXB编组为XML的Object。一个元素包含一个包含引号（）的字符串。生成的XML具有& quot; 其中存在。

即使这通常是首选，我也需要输出匹配传统系统。如何强制JAXB不转换HTML实体？

感谢您的回复。但是，我从未看到调用处理程序escape（）。你能看一看，看看我做错了什么吗？谢谢！

  package org.dc.model; 
 
 import java.io.IOException; 
 import java.io.Writer; 
 
 import javax.xml.bind.JAXBContext; 
 import javax.xml.bind.JAXBException; 
 import javax.xml.bind.Marshaller; 
 
 import org.dc.generated.Shiporder; 
 
 import com.sun.xml.internal.bind.marshaller.CharacterEscapeHandler; 
 
 public class PleaseWork {
 public void prettyPlease（）throws JAXBException {
 Shiporder shipOrder = new Shiporder（）; 
 shipOrder.setOrderid（订单ID）; 
 shipOrder.setOrderperson（女人说，\你是怎么做的东西？\）; 
 
 JAXBContext context = JAXBContext.newInstance（org.dc.generated）; 
 Marshaller marshaller = context.createMarshaller（）; 
 marshaller.setProperty（Marshaller.JAXB_FORMATTED_OUTPUT，Boolean.TRUE）; 
 marshaller.setProperty（CharacterEscapeHandler.class.getName（），
 new CharacterEscapeHandler（）{
 @Override 
 public void escape（char [] ch，int start，int length， 
 boolean isAttVal，Writer out）抛出IOException {
 out.write（called escape for characters =+ ch.toString（））; 
} 
}）; 
 marshaller.marshal（shipOrder，System.out）; 
} 
 
 public static void main（String [] args）抛出异常{
 new PleaseWork（）。prettyPlease（）; 
} 
}

输出为：

 <？xml version =1.0encoding =UTF-8 standalone =yes？> 
< shiporder orderid =订单ID> 
< orderperson>女人说，& quot; ya doin& amp;东西&安培; QUOT;< / orderperson> 
< / shiporder> 
  

如您所见，回调永远不会显示。 （一旦我收到回叫，我会担心它实际上做了我想要的。）

解决方案

解决方案我的队友发现：

  PrintWriter printWriter = new PrintWriter（ new FileWriter（xmlFile））; 
 DataWriter dataWriter = new DataWriter（printWriter，UTF-8，DumbEscapeHandler.theInstance）; 
 marshaller.marshal（request，dataWriter）; 
  

不要将xmlFile传递给marshal（），而是传递知道编码和适当的DataWriter转义处理程序，如果有的话。

注意：由于DataWriter和DumbEscapeHandler都在com.sun.xml.internal.bind.marshaller包中，因此必须引导javac。 / p>

I have an Object that is being marshalled to XML using JAXB. One element contains a String that includes quotes ("). The resulting XML has " where the " existed.

Even though this is normally preferred, I need my output to match a legacy system. How do I force JAXB to NOT convert the HTML entities?

Thank you for the replies. However, I never see the handler escape() called. Can you take a look and see what I'm doing wrong? Thanks!

package org.dc.model;

import java.io.IOException;
import java.io.Writer;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

import org.dc.generated.Shiporder;

import com.sun.xml.internal.bind.marshaller.CharacterEscapeHandler;

public class PleaseWork {
    public void prettyPlease() throws JAXBException {
        Shiporder shipOrder = new Shiporder();
        shipOrder.setOrderid("Order's ID");
        shipOrder.setOrderperson("The woman said, \"How ya doin & stuff?\"");

        JAXBContext context = JAXBContext.newInstance("org.dc.generated");
        Marshaller marshaller = context.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
        marshaller.setProperty(CharacterEscapeHandler.class.getName(),
                new CharacterEscapeHandler() {
                    @Override
                    public void escape(char[] ch, int start, int length,
                            boolean isAttVal, Writer out) throws IOException {
                        out.write("Called escape for characters = " + ch.toString());
                    }
                });
        marshaller.marshal(shipOrder, System.out);
    }

    public static void main(String[] args) throws Exception {
        new PleaseWork().prettyPlease();
    }
}

The output is this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<shiporder orderid="Order's ID">
    <orderperson>The woman said, &quot;How ya doin &amp; stuff?&quot;</orderperson>
</shiporder>

and as you can see, the callback is never displayed. (Once I get the callback being called, I'll worry about having it actually do what I want.)

解决方案

Solution my teammate found:

PrintWriter printWriter = new PrintWriter(new FileWriter(xmlFile));
DataWriter dataWriter = new DataWriter(printWriter, "UTF-8", DumbEscapeHandler.theInstance);
marshaller.marshal(request, dataWriter);

Instead of passing the xmlFile to marshal(), pass the DataWriter which knows both the encoding and an appropriate escape handler, if any.

Note: Since DataWriter and DumbEscapeHandler are both within the com.sun.xml.internal.bind.marshaller package, you must bootstrap javac.
