This is the solution for my old question:
I implemented my own ContextResolver
in order to enable the DeserializationConfig.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY
feature.
package org.lig.hadas.services.mapper;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;
import org.codehaus.jackson.map.DeserializationConfig;
import org.codehaus.jackson.map.ObjectMapper;
@Produces(MediaType.APPLICATION_JSON)
@Provider
public class ObjectMapperProvider implements ContextResolver<ObjectMapper>
{
ObjectMapper mapper;
public ObjectMapperProvider(){
mapper = new ObjectMapper();
mapper.configure(DeserializationConfig.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);
}
@Override
public ObjectMapper getContext(Class<?> type) {
return mapper;
}
}
And in the web.xml
I registered my package into the servlet definition...
<servlet>
<servlet-name>...</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>...;org.lig.hadas.services.mapper</param-value>
</init-param>
...
</servlet>
... all the rest is transparently done by jersey/jackson.
