I am facing an issue while marshalling a java class.
In code snippet 1, Class A use List<B> whereas snippet 2 has List<B<? extends C>>.
Code snippet 1 produces <?xml version="1.0" encoding="UTF-8" standalone="yes"?><a><test><item><name>Success!!</name></item></test></a>
whereas snippet 2 is missing data inside Class C <?xml version="1.0" encoding="UTF-8" standalone="yes"?><a><test/></a>
Can someone please help me resolve this?
Snippet 1:
public class JaxBXMLTest {
@Test
public void testMarshalling() throws JAXBException{
testBaseClass();
}
private void testBaseClass() throws JAXBException{
A resp = new A();
C test = new C();
test.setName("Success!!");
List<B> data = new ArrayList<B>();
B wrap = new B();
wrap.setItem(test);
data.add(wrap);
resp.setTest(data);
JAXBContext context = JAXBContext.newInstance(A.class);
Marshaller m = context.createMarshaller();
//for pretty-print XML in JAXB
// Write to System.out for debugging
m.marshal(resp, System.out);
}
@XmlRootElement
@XmlType(name = "MyResponse")
public static class A{
List<B> test;
public List<B> getTest() {
return test;
}
public void setTest(List<B> test) {
this.test = test;
}
}
public static class B{
private C item;
public C getItem() {
return item;
}
public void setItem(C item) {
this.item = item;
}
}
public static class C{
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
}
Snippet 2:
public class JaxBXMLTestB {
@Test
public void testMarshalling() throws JAXBException {
testSubClass();
}
private void testSubClass() throws JAXBException {
A resp = new A();
C test = new C();
test.setName("Failure!!!");
B<? extends C> wrap = new B<C>();
wrap.setItem(test);
List<B<? extends C>> finalObj = new ArrayList<B<? extends C>>();
finalObj.add(wrap);
resp.setTest(finalObj);
JAXBContext context = JAXBContext.newInstance(A.class);
Marshaller m = context.createMarshaller();
// for pretty-print XML in JAXB
// m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
// Write to System.out for debugging
m.marshal(resp, System.out);
}
@XmlRootElement
@XmlType(name = "MySubClassResponse")
public static class A {
List<B<? extends C>> test;
public A(){
test = new ArrayList<B<? extends C>>();
}
public List<B<? extends C>> getTest() {
return test;
}
public void setTest(List<B<? extends C>> test) {
this.test = test;
}
}
public static class B<T extends C> {
private T item;
public T getItem() {
return item;
}
public void setItem(C item) {
this.item = (T) item;
}
}
public static class C {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
}
