I have migrated my application from Jersey 1.x to 2.x and I am trying to replace the following entry from the web.xml
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
in order to be able to get entities as json.
I have read in the official documentation that I have to use the Jackson provider by adding jersey-media-json-jackson dependency and thne register the JacksonFeature.
I added the following dependency:
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.4.1</version>
</dependency>
but now I don't know what I have to add in my web.xml
file as a value in the
<param-name>jersey.config.server.provider.packages</param-name>
Any ideas ? I wan't to do it via a configuration file like web.xml and not inside my code.
My configuration looks like this:
<servlet>
<servlet-name>REST Service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.<your-company-name-here></param-value>
</init-param>
<init-param>
<param-name>jersey.config.beanValidation.enableOutputValidationErrorEntity.server</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
I register everything using a ResourceConfig
class. I also found a resource that describes how to do it other ways ( http://blog.dejavu.sk/2013/11/19/registering-resources-and-providers-in-jersey-2/ ).
@ApplicationPath("/ws")
public class WsResourceConfig extends ResourceConfig {
public WsResourceConfig() {
register(Jackson2Feature.class);
register(ObjectMapperResolver.class);
//register(MultiPartFeature.class); // if needed
//register(new LoggingFilter(LOGGER, true)); // to enable logging
//register(my resources...); to register my service classes
}
private static class ObjectMapperResolver implements ContextResolver<ObjectMapper> {
private static ObjectMapper mapper = new ObjectMapper();
static {
// configure mapper here
}
@Override
public ObjectMapper getContext(Class<?> type) {
return mapper;
}
}
/**
* Feature to disable Moxy and Enable Jackson processing
*/
private static class Jackson2Feature implements Feature {
@Override
public boolean configure(FeatureContext context) {
final String disableMoxy = PropertiesHelper.getPropertyNameForRuntime(
CommonProperties.MOXY_JSON_FEATURE_DISABLE,
context.getConfiguration().getRuntimeType());
context.property(disableMoxy, true);
// add the default Jackson exception mappers and allow jaxb annotations
context.register(JsonParseExceptionMapper.class);
context.register(JacksonJaxbJsonProvider.class, MessageBodyReader.class, MessageBodyWriter.class);
return true;
}
}
