在编组期间，每个元素中的jaxb名称空间而不是根元素 [英] jaxb namespaces in each element instead of root element during marshalling

问题描述

默认情况下，jaxb 2在编组期间列出根元素中的所有（所有可能需要的）名称空间：

By default, jaxb 2 lists all (all possible required) namespaces in root element during marshalling:

< rootElement xmlns =default_nsxmlns：ns1 =ns1xmlns：ns2 =ns2>
< ns1：element />
< / rootElement>

有没有办法在每个元素中描述命名空间根元素？：

Is there a way to describe namespace in each element instead of root element ?:

< rootElement xmlns =default_ns>
< element xmlns =ns1/>
< / rootElement>

它还解决了不必要的命名空间问题，这对我来说也很重要。
任何建议表示赞赏。

It also solves the problem of "unnecessary namespaces", which is also important in my case. Any suggestions appreciated.

推荐答案

此外，我倾向于同意@Anton在其他人提供的回复中线。
我真的不应该重要。如果你必须强迫某种方式，你应该总是更喜欢顶级上下文，特别是如果你有可能重复的元素。在兄弟元素中重复名称空间声明是浪费空间，也是接收端解析器的次优。

Also, I tend to agree wtih @Anton in the response he offered in the other thread. I really shouldn't matter. And if you must force one way or the other, you should always prefer the top-level context, especially if you have potentially repeated elements. Repeating the namespace declaration in sibling elements is a waste of space as well as sub-optimal for the parser at the receiving end.
