java - Anonymous inner classes JAXB serialization -

-

i tried use anonymous inner classes initializers syntax serialize jaxb generated objects, , noticed works on endpoints not resttemplate. wondering why working in 1 case , not other?

to give example, sample endpoint in spring returns jaxb generated profile instance:

@payloadroot(namespace = namespace_uri, localpart = service_name) @responsepayload public profile getprofile(@requestpayload  getprofile request) {      // stuff service returns profile     return service.dostuff(request);  }

now, when have service returning anonymous instance of profile, there no serialization issues:

return new profile() {      {         setbirthday(user.getbirthday());         setemailaddress(user.getemailaddress());         setfirstname(user.getfirstname());         setgender(user.getgen());         // , on     } };

however, when try use anonymous inner classes argument resttemplate, jaxb error regarding not supported anonymous classes.

"a non-static inner class, , jaxb can't handle those. problem related following location..."

    private updateprofile createupdateprofilerequest(final updateprofile request) {       return new updateprofile() {          {             setprofilev2(getprofile(request));         }     };  }   private profilev2 getprofile(updateprofile request) {      profilev2 profile = new profilev2();      profileupdate profileupdate = request.getprofileupdate();      profile.setbirthday(profileupdate.getbirthday());     profile.setfirstname(profileupdate.getfirstname());       return profile;  }

i have read post: what double brace initialization in java?

and don't have use case these objects turn container managed singletons - memory leaks.

there mention of serialization issues, no details , understand this.

since using jaxb serialization on endpoints too, why possible jaxb serialize such objects outgoing data on endpoints not within resttemplate.postforobject(...).
