RestEasy, how to prevent marshalling of JAXB annotated POJOs to and from JSON -

i started service consumes , produces output in json. utilize resteasy-jackson-provider (de)marshalling takes info class description. after while asked add together xml mediatype. annotated dtos jaxb annotations , added resteasy-jaxb-provider. result, observed produced json output derives jaxb annotations differs original format.

i on resteasy version 3.0.4. described utilize next providers

resteasy-jackson-provider resteasy-axb-provider. resteasy-jettison-provider, because integrated resteasy spring , provider transitive dependency.

i got aware of problem when

used xmlelementwrapper lists , when

i wrote custom xmladapter serializes complex info construction map<string, list<string>>. requests xml mediatype fine. requests json mediatype cause exception. jackson seems exploit xmladapter farther information. not case before. jackson able marshall map without jaxb annotations.

so, how can prevent resteasy using jaxb annotations marshalling , json?

here request class:

@xmlaccessortype(xmlaccesstype.field) @xmlrootelement(name = "domainrecommendationrequest") public class request { @xmljavatypeadapter(optionalparametersxmladapter.class) private map<string, list<string>> optional = new hashmap<>(); }

here xmladapter:

@override public class optionalparametersxmladapter extends xmladapter<optionalparametersmaptype, map<string, list<string>>> { public optionalparametersmaptype marshal(map<string, list<string>> v) throws exception { optionalparametersmaptype result = new optionalparametersmaptype(); list<optionalparameteritemtype> optionalparameteritemtypes = new arraylist<>(); set<string> keyset = v.keyset(); (string parametername : keyset) { optionalparameteritemtype item = new optionalparameteritemtype(); item.name = parametername; item.values = v.get(parametername); optionalparameteritemtypes.add(item); } result.parameter = optionalparameteritemtypes; homecoming result; } }

here wrapper map:

public class optionalparametersmaptype { public list<optionalparameteritemtype> parameter = new arraylist<>(); }

here actual map entry item:

public class optionalparameteritemtype { @xmlattribute public string name; @xmlelementwrapper(name = "values") @xmlelement(name = "value") public list<string> values = new arraylist<>(); }

this expect in json request:

{"optional":{"customer":["mike"]}}

as can see, intend have different format in xml.

the problem resteasy-jackson-provider depends on jackson-module-jaxb-annotations, used map jaxb annotations/annotated classes json. in normal explicit utilize of objectmapper, in order create utilize of module, need explicitly register module (see here)

objectmapper objectmapper = new objectmapper(); jaxbannotationmodule module = new jaxbannotationmodule(); objectmapper.registermodule(module); -- or -- annotationintrospector introspector = new jaxbannotationintrospector(); objectmapper.setannotationintrospector(introspector);

that beingness said, appears (not confirmed facts, looks probable) when objectmapper beingness created serialization, when jaxb annotations noticed, module automatically registered.

i don't know of possible annotations can utilize stop this, 1 way solve problem create contextresolver objectmapper, don't register jaxb module.

@provider public class objectmappercontextresolver implements contextresolver<objectmapper> { @override public objectmapper getcontext(class<?> type) { homecoming new objectmapper(); } }

once register our jax-rs application, context resolver used objectmapper. configure objectmapper further, example. test , works expected.
