Srinivas Nagulapalli commented on CXF-5988:
-------------------------------------------
We tried using ParamConverter with no effect. Converter code and client side
configuration to register it are below:
Please note, this approach works for the server-side but not on the client-side.
// SomeDateConverter.java//
package com.my.util;
import java.util.Date;
import javax.ws.rs.ext.ParamConverter;
import org.joda.time.DateTime;
import org.joda.time.DateTimeZone;
import org.joda.time.format.DateTimeFormatter;
import org.joda.time.format.ISODateTimeFormat;
public class SomeDateConverter implements ParamConverter<Date> {
@Override
public Date fromString(String dateString) {
if (dateString.contains("-")) {
DateTime result =
ISODateTimeFormat.dateTimeParser().withZone(DateTimeZone.UTC).parseDateTime(dateString);
return result.toDate();
}
return new Date(Long.parseLong(dateString));
}
@Override
public String toString(Date dateToConvert) {
return
ISODateTimeFormat.dateTime().withZone(DateTimeZone.UTC).print(dateToConvert.getTime());
}
}
// ParamConverterProviderImpl.java//
package com.my.util;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import java.util.Map;
import javax.ws.rs.ext.ParamConverter;
import javax.ws.rs.ext.ParamConverterProvider;
public class ParamConverterProviderImpl implements ParamConverterProvider {
private final Map<Class<?>, ? extends ParamConverter<?>> paramConverters;
public ParamConverterProviderImpl(Map<Class<?>, ? extends
ParamConverter<?>> paramConverters) {
this.paramConverters = paramConverters;
}
@Override
public <T> ParamConverter<T> getConverter(Class<T> rawClass, Type
genericType, Annotation[] annotations) {
return (ParamConverter<T>) paramConverters.get(rawClass);
}
}

> Key: CXF-5988
> URL: https://issues.apache.org/jira/browse/CXF-5988
> Project: CXF
> Issue Type: Bug
> Components: Core, JAX-RS
> Affects Versions: 3.0.1
> Environment: Windows 7
> Reporter: Srinivas Nagulapalli
> Labels: patch
> Fix For: 3.0.1
>
>
> Server-side JAX-RS implementation allows injection of custom parameter
> converters using ParamConverterProvider
> (http://cxf.apache.org/docs/jax-rs-basics.html#JAX-RSBasics-Parameterconverters).
> A similar mechanism (or the exact same) is required on the client side to
> control how parameters are serialized (marshalled). One approach is to allow
> specifying param converters when declaring jaxrs:client with Spring and/or
> programmatically specifying it.
> A specific case to consider: Client side serialization of Date object
> (java.util.Date).
> Given the following API:
> @Path(“/someresource”)
> @GET
> void someApi(@MatrixParam(“”) SomeRequestWithDate request);
>
> Following shows the structure of the request with Dates:
> //----------------------------------------------------
> import java.util.Date;
> public class SomeRequestWithDate {
> protected Date startDate;
>
> public Date getStartDate() {
> return startDate;
> }
> }
> //----------------------------------------------------
> When API is invoked through a client proxy
> Then the following URL should be generated (where dates are serialized as ISO
> strings):
> /someresource/;startDate=2014-09-04T19:05:38.785Z
> Instead, currently following URL is generated:
> /someresource/;startDate.date=4;startDate.hours=15;startDate.minutes=4;startDate.month=8;startDate.seconds=34;startDate.time=1409857474660;startDate.year=114;startDate.day=4;startDate.timezoneOffset=240
