JAXB Marshaller和输出XML的格式 [英] JAXB Marshaller and Formatting of output XML
本文介绍了JAXB Marshaller和输出XML的格式的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我关注这篇文章:
JAXB Marshaller缩进
I was following this post:
JAXB Marshaller indentation
但是我遇到了一个错误:
But I ran to an error:
org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.
这实际上与我使用过的Marshaller有关:
Which actually pertains to the Marshaller I have used when it did:
marshaller.marshal(instance, domResult);
您的意见和建议非常受欢迎。
Your comments and opinions are highly appreciated.

推荐答案
我通过调整Antonio Maria Sanchez的答案解决了我的问题位。
参考: JAXB Marshaller缩进
I fixed my problem by tweaking Antonio Maria Sanchez's answer a bit.
Reference: JAXB Marshaller indentation
所以这是我的答案:
So here is my answer:
import java.io.File;
import java.io.FileNotFoundException;
import java.io.StringReader;
import java.io.StringWriter;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import javax.xml.transform.OutputKeys;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
public class ObjectToXMLWriter {
public static <Type> boolean writeToFileWithXmlTransformer(Type instance
,String fullFileNamePath) throws FileNotFoundException {
boolean isSaved = false;
JAXBContext jaxBContent = null;
Marshaller marshaller = null;
StringWriter stringWriter = new StringWriter();
try {
jaxBContent = JAXBContext.newInstance(instance.getClass());
marshaller = jaxBContent.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(instance, stringWriter);
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
transformer.transform(new StreamSource(new StringReader(stringWriter.toString()))
,new StreamResult(new File(fullFileNamePath)));
isSaved = true;
} catch(JAXBException jaxBException) {
System.out.println("JAXBException happened!");
jaxBException.printStackTrace();
} catch(Exception exception) {
System.out.println("Exception happened!");
exception.printStackTrace();
}
return isSaved;
}
}
关键点这个答案如下:
The critical points to this answer are the following:
- marshaller.marshal(instance,stringWriter);
- 而不是使用DOMResult
- 而不是使用DOMSource
