如何使用JAXB设置默认命名空间 [英] How to set the default namespace using JAXB
问题描述
我有一个通过Spring MVC Web服务返回的数据的ATOM-XML表示。我正在使用JAXB进行序列化,我有许多名称空间但我希望默认名称空间设置为Atom而没有前缀。以下是我目前在 package-info.java
中的内容,但原子前缀设置为ns3。
I have a ATOM-XML representation of my data that is returned via a Spring MVC web service. I'm using JAXB to do the serialization, I have a number of namespaces but I want the default namespace set to Atom with no prefix. Here is what I have so far in package-info.java
but the atom prefix is being set to ns3.
@XmlSchema(namespace = com.mycomponay.foo.ATOM_NAMESPACE,
xmlns = {
@XmlNs(prefix = "foo", namespaceURI = com.mycomponay.foo.NAMESPACE_FOO),
}, elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.mycompany.web;
import javax.xml.bind.annotation.XmlNs;
此外,我注意到命名空间显示在chrome中,但不显示在Firefox中。
Also I noticed the namespaces display in chrome but not in Firefox.
推荐答案
尝试添加 @XmlNs
注释,前缀为用于要显示为默认名称的命名空间。
Try adding an @XmlNs
annotation with prefix ""
for the namespace you want to appear as the default.
@XmlSchema(
namespace = com.mycompany.foo.ATOM_NAMESPACE,
xmlns = {
@XmlNs(prefix = "", namespaceURI = com.mycompany.foo.ATOM_NAMESPACE),
@XmlNs(prefix = "foo", namespaceURI = com.mycompany.foo.NAMESPACE_FOO)
},
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.mycompany.web;
import javax.xml.bind.annotation.*;
注意:
@XmlSchema
注释中指定的命名空间旨在影响XML架构的生成,并且不保证在将对象模型编组为XML时使用。但是 EclipseLink JAXB(MOXy) 和最新版本的< a href =https://jaxb.java.net/ =noreferrer> JAXB参考实现将尽可能使用它们。
The namespaces specified in the @XmlSchema
annotation are meant to affect the generation of the XML Schema and are not guaranteed to be used when a object model is marshalled to XML. However EclipseLink JAXB (MOXy) and recent versions of the JAXB reference implementation will use them whenever possible.
