Easiest frameworks to implement Java REST web services [closed]

Answer 1

Jersey is really easy for both. To write web services, you use annotations:

@Path("/helloworld")
public class HelloWorldResource {

    // The Java method will process HTTP GET requests
    @GET
    // The Java method will produce content identified by the MIME Media
    // type "text/plain"
    @Produces("text/plain")
    public String helloWorld() {
        // Return some cliched textual content
        return "Hello World";
    }
}

For a client:

Client client = Client.create();
WebResource webResource = client.resource("http://localhost:8080/helloworld");
String s = webResource.get(String.class);
System.out.println(s); // prints Hello World

Answer 2

I can recommend Apache wink, a new framework still in incubation mode, but very mature and high quality.

http://incubator.apache.org/wink/

It implements the JAX-RS specification, it has both client & server framework for REST development. Apache is standing behind this project - that's always a good sign (and a good license :-) )

What I love most about this framework is the intuitive integration with Spring, it's very useful if you want your framework to be easily configured and extended.

You could take a look at the CXF JAX-RS implementation. For complete list of its features check the CXF web site for JAX-RS. The community behind the project seems to be very active (July 2013). An indication of that is the number of messages per day in the CXF mailing lists.

Take a look at dropwizard too.
