从生成的XML中删除“独立=”yes”

Do you know of a JAXB setting to prevent standalone="yes" from being generated in the resulting XML?

您知道JAXB设置防止在生成的XML中生成独立=“yes”吗?

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

9 个解决方案

#1

marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", Boolean.FALSE);

can be used to have no

能习惯没有吗

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

However i wouldnt consider this best practice.

但是我不认为这是最好的做法。

in JAXB that is part of JDK1.6

在JAXB中，这是JDK1.6的一部分

marshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);

#3

You can either use

可以使用

marshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);

或

marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", Boolean.FALSE)

to disable the default XML declaration, and then add your custom XML declaration,

要禁用默认的XML声明，然后添加自定义的XML声明，

<?xml version="1.0" encoding="UTF-8"?>

通过

marshaller.setProperty("com.sun.xml.bind.xmlHeaders",
      "<?xml version=\"1.0\" encoding=\"UTF-8\"?>");

to the generated xml, thus avoiding the standalone="yes" property.

到生成的xml，从而避免独立的=“yes”属性。

#4

If you make document dependent on DOCTYPE (e.g. use named entities) then it will stop being standalone, thus standalone="yes" won't be allowed in XML declaration.

如果您使文档依赖于DOCTYPE(例如使用命名实体)，那么它将停止独立，因此在XML声明中不允许独立=“yes”。

However standalone XML can be used anywhere, while non-standalone is problematic for XML parsers that don't load externals.

然而，独立的XML可以在任何地方使用，而非独立的XML解析器则存在问题，因为它们不加载外部文件。

I don't see how this declaration could be a problem, other than for interoperability with software that doesn't support XML, but some horrible regex soup.

除了与不支持XML的软件进行互操作之外，我不认为这个声明会成为一个问题，而是看到了一些可怕的regex soup。

#5

just if someone else is still struggeling with this problem, you may consider using

如果别人还在为这个问题苦苦挣扎，你可以考虑使用它

marshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);

to remove all of the XML declaration and just write your own String at the beginning of your output stream / method

要删除所有XML声明，只需在输出流/方法的开头编写自己的字符串

#6

jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
jaxbMarshaller.setProperty("com.sun.xml.internal.bind.xmlHeaders", "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>");

This worked for me with JDK1.7. standalone=\"no\" can be removed to get only rest of the xml part

这对我的JDK1.7有效。独立=\“no\”可以删除，只获取xml部分的其余部分

#7

If you are using only the default javax.xml package, you could set the JAXB_FRAGMENT option of the marshaller to 'true' (this omits the default xml processing instruction) and use the writeProcessingInstruction method of the XMLStreamWriter to insert your own:

如果您只使用默认的javax。可以将封送器的JAXB_FRAGMENT选项设置为“true”(省略了默认的xml处理指令)，并使用XMLStreamWriter的writeprocessinginstructions方法插入您自己的:

xmlStreamWriter.writeProcessingInstruction("xml", "version=\"1.0\" encoding=\"UTF-8\"");
jaxbMarshaller.setProperty( Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
jaxbMarshaller.marshal(object, xmlStreamWriter);
xmlStreamWriter.writeEndDocument();

#8

You can use: marshaller.setProperty("jaxb.fragment", Boolean.TRUE);

可以使用:marshaller.setProperty(“jaxb.fragment”，Boolean.TRUE);

It works for me on Java 8

它适用于Java 8

I don't have a high enough "reputation" to have the "privilege" to comment. ;-)

我没有足够高的“声誉”来发表评论。:-)

@Debasis, note that the property you've specified:

@Debasis，注意您指定的属性:

"com.sun.xml.internal.bind.xmlHeaders"

should be:

应该是:

"com.sun.xml.bind.xmlHeaders" (without the "internal", which are not meant to be used by the public)

If I use the "internal" property as you did, I get a javax.xml.bind.PropertyException

如果我像您那样使用“内部”属性，就会得到javax.xml.bin . propertyexception

#1

marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", Boolean.FALSE);
