Examples for Chapter 7 - RESTful Java with JAX-RS 2.0 - page 295

The last thing we have to do is modify our Application class to register the Excep-
tionMapper :

src/main/java/com/restfully/shop/services/ShoppingApplication.java

public public class class ShoppingApplication ShoppingApplication extends extends Application {

private private Set < Object > singletons = new new HashSet < Object >();

private private Set < Class <?>> classes = new new HashSet < Class <?>>();

public public ShoppingApplication ()

{

singletons . add ( new new CustomerResource ());

classes . add ( CustomerNotFoundExceptionMapper . class );

}

@Override
public

public Set < Class <?>> getClasses ()
{

return return classes ;

}

@Override
public

public Set < Object > getSingletons ()
{

return return singletons ;

}

}

The Client Code

The client code for this example is very simple. We make a GET request to a customer re-
source that doesn't exist:

src/test/java/com/restfully/shop/test/CustomerResourceTest.java

package package com . restfully . shop . test ;

import import javax.ws.rs.NotFoundException javax.ws.rs.NotFoundException ;

...

@Test
public

public void void testCustomerResource () throws throws Exception

{

try try

{
