java - How to convert a Date between Jackson and Gson? -

in our spring-configured rest-server use jackson convert object json. object contains several java.util.date objects.

when attempt deserialize on android device using gson's fromjson method "java.text.parseexception: unparseable date". have tried serializing date timestamp corresponding milliseconds since 1970, same exception.

can gson configured parse timestamp-formatted date such 1291158000000 java.util.date object?

you need register own deserializer dates.

i've created small example below, in json string "23-11-2010 10:00:00" deserialized date object:

import java.lang.reflect.type; import java.text.parseexception; import java.text.simpledateformat; import java.util.date;  import com.google.gson.gson; import com.google.gson.gsonbuilder; import com.google.gson.jsondeserializationcontext; import com.google.gson.jsondeserializer; import com.google.gson.jsonelement; import com.google.gson.jsonparseexception;   public class dummy {     private date date;      /**      * @param date date set      */     public void setdate(date date) {         this.date = date;     }      /**      * @return date      */     public date getdate() {         return date;     }      public static void main(string[] args) {         gsonbuilder builder = new gsonbuilder();         builder.registertypeadapter(date.class, new jsondeserializer<date>() {              @override             public date deserialize(jsonelement json, type typeoft, jsondeserializationcontext context)                     throws jsonparseexception {                  simpledateformat format = new simpledateformat("dd-mm-yyyy hh:mm:ss");                 string date = json.getasjsonprimitive().getasstring();                 try {                     return format.parse(date);                 } catch (parseexception e) {                     throw new runtimeexception(e);                 }             }         });         gson gson = builder.create();         string s = "{\"date\":\"23-11-2010 10:00:00\"}";         dummy d = gson.fromjson(s, dummy.class);         system.out.println(d.getdate());     } }
