Question

The client may request two urls with the same path but different query strings:

1. /hello
2. /hello?name=Mike

How to use jersey to define two different methods for each of them?

Here is an example:

@Path("/hello") 
public class HelloResource {

    @Produces("text/plain")
    public String justHello() {}

    // how to call this method only the query string has "name"
    @Produces("text/plain")
    public String helloWithName() {}
}

You can’t do this, Jersey only matches the path. See http://jersey.java.net/nonav/documentation/latest/jax-rs.html for full details.

You can build your own switch based on the query parameter being present. In general, name=mike is not very RESTy anyways. Jersey does support:

 /hello/{name}

And that’s the way it’s meant to be used.
