java - Serialize proxy object created by cglib -

as title, use jersey return object json, object created cglib proxy:

@get @produces(mediatype.application_json) @path("test") public response test() {     enhancer enhancer = new enhancer();     enhancer.setsuperclass(a.class);     enhancer.setcallback(new invocationhandler() {         public object invoke(object proxy, method method, object[] args) throws throwable {             return "my name";         }     });     return response.ok(enhancer.create()).build(); }  @data @xmlaccessortype(xmlaccesstype.property) public static class {     private string name; } 

it cannot work because enhancer.create() return proxy object of class a, not real object of class a.

org.codehaus.jackson.map.jsonmappingexception: no serializer found class myrest$1 , no properties discovered create beanserializer (to avoid exception, disable serializationconfig.feature.fail_on_empty_beans) ) (through reference chain: myrest$a$$enhancerbycglib$$fdcf8406["callbacks"])

the problem encounter cglib creates subclass of class not copy annotations. @ same time, annotations not inherited if not explicitly defined.

cglib not support annotations. overcome this, can choose use code generation library supports annotations. wrote such library, called byte buddy.
