Examples for Chapter 9 - RESTful Java with JAX-RS 2.0 - page 298

@GET
@Path ( "{id}" )
@Produces ( "text/plain" )
public public Customer getCustomerString ( @PathParam ( "id" ) int int id )

{

return return getCustomer ( id ). toString ();

}

The Client Code

The client code for this example executes various HTTP GET requests to retrieve different
representations of a Customer . Each request sets the Accept header a little differently so that
it can obtain a different representation. For example:
src/test/java/com/restfully/shop/test/CustomerResourceTest.java

public public class class CustomerResourceTest CustomerResourceTest

{

@Test
public

public void void testCustomerResource () throws throws Exception

{

... initialization code ...

System . out . println ( "*** GET XML Created Customer **" );
String xml = client . target ( location ). request ()
. accept ( MediaType . APPLICATION_XML_TYPE )
. get ( String . class );

System . out . println ( xml );

System . out . println ( "*** GET JSON Created Customer **" );
String json = client . target ( location ). request ()
. accept ( MediaType . APPLICATION_JSON_TYPE )
. get ( String . class );
System . out . println ( json );

}

}

The SyncInvoker.accept() method is used to initialize the Accept header. The client ex-
tracts a String from the HTTP response so it can show you the request XML or JSON.
