问题描述
我使用MOXy作为JAXB实现但不知何故我想在某些管理界面(动态)显示实现名称(例如Moxy)和版本号。
I am using MOXy as JAXB Implementation but somehow I would like to show the Implementation Name (e.g. Moxy) and the version number on some admin screen (dynamically).
如何从JAXB中检索该信息?
How can I retrieve that info from JAXB?

推荐答案
您可以执行以下操作来确定正在使用的JAXB impl:
You could do something like the following to figure out the JAXB impl being used:
import javax.xml.bind.JAXBContext;
public class Demo {
private static final String MOXY_JAXB_CONTEXT = "org.eclipse.persistence.jaxb.JAXBContext";
private static final String METRO_JAXB_CONTEXT = "com.sun.xml.bind.v2.runtime.JAXBContextImpl";
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Root.class);
String jaxbContextImpl = jc.getClass().getName();
if(MOXY_JAXB_CONTEXT.equals(jaxbContextImpl)) {
System.out.println("EclipseLink MOXy");
} else if(METRO_JAXB_CONTEXT.equals(jaxbContextImpl)) {
System.out.println("Metro");
} else {
System.out.println("Other");
}
}
}
你可以从它的Version类获取有关正在使用的EclipseLink版本的信息:
You can get information about the EclipseLink version being used from it's Version class:
import org.eclipse.persistence.Version;
public class VersionDemo {
public static void main(String[] args) {
System.out.println(Version.getVersion());
}
}
