java - Generic Map<String, Object> JSON marshalling and unmarshalling with Moxy -

is there way marshal map<string, object> moxy json result uses natural constructs of json?
is, keys strings , possible values following rules apply (possibly not complete set):

• number (e.g., integer) becomes json number (or string if it's big)
• string becomes json string
• set, array, iterable become json array
• and map<string, object>, same rules recursively applied
• any other object marshalled in natural moxy way

there example how marshal map<string, integer> , other specific maps using @xmlvariablenode (see http://blog.bdoughan.com/2013/06/moxys-xmlvariablenode-using-maps-key-as.html?m=1), unable extend idea point subtypes can inserted value.

note moxy should able unmarshal json original map.

jackson capable of doing default.

i've tried want jaxb ri (xml):

@xmlrootelement public class foo {     @xmljavatypeadapter(mapadapter.class)     public map<string, object> map; }  public class mapadapter extends xmladapter<mapentry[], map<string, object>> {     @override     public map<string, object> unmarshal(mapentry[] v) throws exception {         map<string, object> map = new hashmap<>();         (mapentry me : v)             map.put(me.key, me.value);         return map;     }     @override     public mapentry[] marshal(map<string, object> v) throws exception {         mapentry[] mes = new mapentry[v.size()];         int = 0;         (map.entry<string, object> entry : v.entryset())             mes[i++] = new mapentry(entry.getkey(), entry.getvalue());         return mes;     } }  public class mapentry {     public string key;     public object value;      public mapentry() {}      public mapentry(string key, object value) {         this.key = key;         this.value = value;     } } 

unfortunately moxy has bug ( https://bugs.eclipse.org/bugs/show_bug.cgi?id=465014 ) , not able handle this.

if need moxy have use approach described in blaise's blog:

@xmlrootelement public class moxyfoo {     @xmljavatypeadapter(moxymapadapter.class)     public map<string, object> map = new hashmap<>(); }  public class moxymapadapter extends xmladapter<moxymapadapter.adaptedmap, map<string, object>> {     @override     public adaptedmap marshal(map<string, object> map) throws exception {         adaptedmap adaptedmap = new adaptedmap();         (entry<string, object> entry : map.entryset()) {             adaptedentry adaptedentry = new adaptedentry();             adaptedentry.key = entry.getkey();             adaptedentry.value = entry.getvalue();             adaptedmap.entries.add(adaptedentry);         }         return adaptedmap;     }     @override     public map<string, object> unmarshal(adaptedmap adaptedmap) throws exception {         list<adaptedentry> adaptedentries = adaptedmap.entries;         map<string, object> map = new hashmap<>(adaptedentries.size());         (adaptedentry adaptedentry : adaptedentries) {             map.put(adaptedentry.key, adaptedentry.value);         }         return map;     }      public static class adaptedmap {         @xmlvariablenode("key")         list<adaptedentry> entries = new arraylist<>();     }      public static class adaptedentry {         @xmltransient         public string key;         @xmlvalue         public object value;     } } 

it's working fine xml, not json. json marshalling working now. i've filled bug fix unmarshalling: https://bugs.eclipse.org/bugs/show_bug.cgi?id=465016 .
