使用eclispelink时，嵌套的@XmlJavaTypeAdapter注释被忽略，其中嵌套对象是通用的
||
编组对象树时，我使用的是
@XmlJavaTypeAdapter
org.eclipse.persistence.jaxb.JAXBContextFactory
@XmlJavaTypeAdapter
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Root.class,C.class);
System.out.println(jc.getClass());
Root root = new Root();
A a = new A();
root.a = a;
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(root, System.out);
}
}
@XmlRootElement
public class Root {
@XmlJavaTypeAdapter(AAdapter.class)
public A a;
}
public class A {
public B b = new B();
}
public class B {
@XmlJavaTypeAdapter(GAdapter.class)
@XmlElement(name=\"b\")
public G<C> gc = new G<C>();
public B(){
gc.t = new C();
}
}
public class C {
public String c = \"Foo\";
}
public class G<T> {
T t;
}
public class AAdapter extends XmlAdapter<B, A> {
@Override
public A unmarshal(B b) throws Exception {
A a = new A();
a.b = b;
return a;
}
@Override
public B marshal(A a) throws Exception {
return a.b;
}
}
public class GAdapter<T> extends XmlAdapter<T, G<T>> {
@Override
public G<T> unmarshal(T c) throws Exception {
return new G<T>();
}
@Override
public T marshal(G<T> g) throws Exception {
return g.t;
}
}
