I\'m trying to pass a java.util.Date to

Answer 1

Percepiton's answer was very useful, but ParameterHandler has been deprecated in Apache-cxf 3.0, see the Apache-cxf 3.0 Migration Guide:

CXF JAX-RS ParameterHandler has been dropped, please use JAX-RS 2.0 ParamConverterProvider.

So I add an example with the ParamConverterProvider :

public class DateParameterConverterProvider implements ParamConverterProvider {

    @Override
    public  ParamConverter getConverter(Class type, Type type1, Annotation[] antns) {
        if (Date.class.equals(type)) {
            @SuppressWarnings("unchecked")
            ParamConverter paramConverter = (ParamConverter) new DateParameterConverter();
            return paramConverter;
        }
        return null;
    }

}

public class DateParameterConverter implements ParamConverter {

    public static final String format = "yyyy-MM-dd"; // set the format to whatever you need

    @Override
    public Date fromString(String string) {
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat(format);
        try {
            return simpleDateFormat.parse(string);
        } catch (ParseException ex) {
            throw new WebApplicationException(ex);
        }
    }

    @Override
    public String toString(Date t) {
        return new SimpleDateFormat(format).format(t);
    }

}

The @SuppressWarnings is required to suppress an "unchecked or unsafe operations" warning during compilation. See How do I address unchecked cast warnings for more details.

The ParamConverterProvider can be registred as provider. Here is how I did it:

  
      
           ...
