CHANGES

0.5.0

We've added a JsonInterceptor and a @Json annotation, so now you can do this:

    @Resource
    public class CustomerController {

        private final Customers customers;

        public CustomerController(Customers customers) {
            this.customers = customers;
        }

        @Json @Get("/customer/byName")
        public List<Customer> findByName(String name){
            return Arrays.asList(customers.findByName(name));
        }
    }

The annotation marks the method to be intercepted, and it will just use the result.use(json()) to serialize the return of the method.

You can exclude some fields too:

    @Resource
    public class CustomerController {

        private final Customers customers;

        public CustomerController(Customers customers) {
            this.customers = customers;
        }

        @Json(exclude = {"address, age"}) @Get("/customer/byName")
        public List<Customer> findByName(String name){
            return Arrays.asList(customers.findByName(name));
        }
    }

0.0.2

We've implemented the exclude funcionality. It works just like the XstreamSerializer.
