@xmlSchema annotation use with jaxb
提问by Fran
I can't get to show in a xml file all the parameters configured with the @xmlSchema annotation at package level. For example, if I set:
我无法在 xml 文件中显示在包级别使用 @xmlSchema 注释配置的所有参数。例如，如果我设置：
@javax.xml.bind.annotation.XmlSchema (
xmlns = {
@javax.xml.bind.annotation.XmlNs(prefix = "com",
namespaceURI="http://es.indra.transporte.common"),
@javax.xml.bind.annotation.XmlNs( prefix = "xsi",
namespaceURI="http://www.w3.org/2001/XMLSchema-instance"),
@javax.xml.bind.annotation.XmlNs( prefix = "ns2",
namespaceURI="http://es.indra.transporte.configuration"),
},
location = "http://es.indra.transporte.configuration StationNetwork.xsd",
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED
)
package es.indra.transporte.central.thalesinterface.common.beans;
I expect to see something like:
我希望看到类似的东西：
<stationNetwork xmlns:ns2="http://es.indra.transporte.configuration"
xmlns:com="http://es.indra.transporte.common"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://es.indra.transporte.configuration StationNetwork.xsd">
but I get the following output:
但我得到以下输出：
<stationNetwork xmlns:com="http://es.indra.transporte.common">
What I'm doing wrong? How can I get the expected output?
我做错了什么？我怎样才能得到预期的输出？

You can write out a schema location as follows:
您可以按如下方式写出架构位置：
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_SCHEMA_LOCATION, "http://es.indra.transporte.configuration StationNetwork.xsd");
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(root, System.out);
Running the following code:
运行以下代码：
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(StationNetwork.class);
StationNetwork root = new StationNetwork();
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_SCHEMA_LOCATION, "http://es.indra.transporte.configuration StationNetwork.xsd");
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(root, System.out);
}
}
