StoreResource
One of the things I want to illustrate with this example is that a client needs to be aware of
only one URL to navigate through the entire system. The
StoreResource
class is the base
URL of the system and publishes
Link
headers to the relevant services of the application:
src/main/java/com/restfully/shop/services/StoreResource.java
@Path
(
"/shop"
)
public
public class
class
StoreResource
StoreResource
{
@HEAD
public

head
(
@Context
UriInfo uriInfo
)
{
UriBuilder absolute
=
uriInfo
.
getBaseUriBuilder

URI customerUrl
=
absolute
.
clone

path
(
CustomerResource
.
class
).
build
