    Configure RESTeasy to serialize date in JSON as ISO-8601 strings

    Thomas Zlika Newbie

      Hi all,

       

      I have a JAX-RS application using JBoss AS 7.1, and I POST/GET JSON and XML objects which include Dates (java.util.Date):

       

      @XmlRootElement
      @XmlAccessorType(XmlAccessField.FIELD)
      public class MyObject implements Serializable
      {
          @XmlSchemaType(name = "dateTime")
          private Date date;
          ...
      }
      

       

       

      When I use @Produce("application/xml") on the get method, the objets are serialized as XML and the dates are converted into ISO-8601 strings (e.g. "2012-12-10T14:50:12.123+02:00").

       

      However, if I use @Produce("application/json") on the get method, the dates in the JSON objects are timestamps (e.g. "1355147452530") instead of ISO-8601 strings.

       

      I also tried to use a custom JAX-RS provider to do the JSON serialization for Dates

       

      @Provider
      @Produces(MediaType.APPLICATION_JSON)
      public class CustomJsonDateProvider implements MessageBodyWriter<Date>
      {
          ...
      }
      

       

       

      This provider seems to be registered by RESTeasy on JBoss startup:

       

          [org.jboss.jaxrs] Adding JAX-RS provider classes: package.CustomJsonDateProvider
          ...
          [org.jboss.resteasy.cdi.CdiInjectorFactory] No CDI beans found for class package.CustomJsonDateProvider. Using default ConstructorInjector.
      

       

       

      but it is never used !

       

      How can I do to configure the JAX-RS implementation (RESTEasy) to serialize dates in JSON format as ISO-8601 strings instead of timestamps ?

       

      Thank you for your answers.
