遇到jaxb框架的一个坑 只能发射类不能反射interface

@xmlElement
标有的对象必须是要class类型，不能是interface

引用

public static String marshal(Object obj) {
OutputStream os = new ByteArrayOutputStream();
String xmlStr = null;
try {
createContext(obj.getClass()).createMarshaller().marshal(obj, os);
xmlStr = os.toString();
} catch (JAXBException e) {
String errorMsg = "Failed to parse the object to xml string with error: " + e.getMessage();
LOGGER.error(errorMsg);
throw new SerializeException(errorMsg, e);
} finally {
if (os != null) {
os = null;
}
}
return xmlStr;
}


createContext(obj.getClass()).createMarshaller().marshal(obj, os);

java.io.Serializable is an interface, and JAXB can't handle interfaces.
