Jaxb:通过xmlns属性而不是元素前缀的本地namspacing? [英] Jaxb: local namspacing via the xmlns attribute instead of the element prefix?
问题描述
我正在使用Jaxb生成一些看起来非常好的XML。这是一个片段:
I'm generating some XML with Jaxb that looks pretty good. Here's a snipit:
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<ns2:oval_system_characteristics xsi:schemaLocation="http://oval.mitre.org/XMLSchema/oval-system-characteristics-5 oval-system-characteristics-schema.xsd http://oval.mitre.org/XMLSchema/oval-common-5 oval-common-schema.xsd http://oval.mitre.org/XMLSchema/oval-system-characteristics-5#esx esx-system-characteristics-schema.xsd"
xmlns:ns2="http://oval.mitre.org/XMLSchema/oval-system-characteristics-5" xmlns="http://oval.mitre.org/XMLSchema/oval-common-5" xmlns:ns3="http://oval.mitre.org/XMLSchema/oval-system-characteristics-5#esx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
...
<ns3:visdkmanagedobject_item id="1">
<ns3:property>isolation.tools.diskWiper.disable</ns3:property>
<ns3:value datatype="boolean">true</ns3:value>
</ns3:visdkmanagedobject_item>
这是符合标准的XML。不幸的是,我受限于下游系统的限制,它只接受以这种方式格式化的XML:
This is standards compliant XML. Unfortunately the I'm limited by the constraints of the downstream system, it only accepts XML formatted this way:
<visdkmanagedobject_item id="1" xmlns="http://oval.mitre.org/XMLSchema/oval-system-characteristics-5#esx">
<property>isolation.tools.diskWiper.disable</property>
<value datatype="boolean">true</value>
</visdkmanagedobject_item>
其中某些元素通过xmlns属性命名空间。
现在问题,如何让Jaxb停止(做正确的事)使用前缀命名空间元素并使用xmlns属性开始命名元素?
Where certain elements are namespaced through the xmlns attribute. Now for the question, how do I get Jaxb to stop (doing the right thing) namespacing the elements with a prefix and start namespacing the elements with the xmlns attribute?
推荐答案
您可以通过在包级别利用 @XmlSchema
注释来设置默认命名空间。这是通过利用 package-info
类(下面的示例)来完成的:
You can setup a default namespace by leveraging the @XmlSchema
annotation at the package level. This is done by leveraging a package-info
class (example below):
com.example。 package-info
@XmlSchema(
namespace = "http://oval.mitre.org/XMLSchema/oval-system-characteristics-5#esx",
elementFormDefault = XmlNsForm.QUALIFIED)
package com.example;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
