Hi All,
I am having problems with a restful service that I have developed (CXF 2.2.7).
I want to pass a List<String> value as a PathParam. I can get this working as a
QueryParam:
@WebService
@Produces("application/json")
@Consumes("application/json")
public interface RestService {
@GET
@Path("/s")
Response doSomething(@QueryParam("strings") List<String> s);
}
using the (truncated) query: /s?strings=s1&strings=s2
However, I'd like to use a PathParam for this. I have tried:
@GET
@Path("/s/{strings}")
Response doSomething(@PathParam("strings") List<String> s);
And also:
@GET
@Path("/s/{strings:.*}")
Response doSomething(@PathParam("strings") List<String> s);
With the query: /s/s1
Which works fine, but:
With the query: /s/s1;s2
I am still only receive the list [s1] (size 1). I have tried other delimiters
such as /s/s1+s2 but this results in the list being [s1+s2] (size 1).
Does anyone know what I am doing wrong?
Also, on a related note, how do I get my proxy client to submit the list in the
correct format for the query? I have a Spring configured service and client
running inside Jetty in my integration tests:
<bean id="restService" class="x.y.z.service.RestServiceImpl" />
<jaxrs:server id="restfulService" address="http://localhost:9002/";>
<jaxrs:serviceBeans>
<ref bean="restService" />
</jaxrs:serviceBeans>
<jaxrs:providers>
<ref bean="listParamHandler" />
</jaxrs:providers>
</jaxrs:server>
<bean id="restClientFactory"
class="org.apache.cxf.jaxrs.client.JAXRSClientFactoryBean">
<property name="serviceClass" value="x.y.z.service.RestServiceImpl" />
<property name="address" value="http://localhost:9002/"; />
</bean>
<bean id="restServiceClient" class="x.y.z.service.RestServiceImpl"
factory-bean="restClientFactory" factory-method="create" />
However, calling:
List<String> strings = new List<String>();
strings.add("s1");
strings.add("s2");
restServiceClient.doSomething(strings);
Results in a call to the server for the URL:
/s/%5Bs1%2C%20s2%5D (/s/[s1, s2])
This is obviously just the result of a List<String>.toString().
So. I have two questions:
1. What is the correct way to submit a String List via a PathParam to a restful
web service?
2. How can I ensure that my proxy based client conforms to this?
I've looked into registering a ParameterHandler provider on the server side but
it doesn't seem to be calling it's fromString method.
Thanks very much for your time,
Matt
