Simple Rest Client is an experiment about a simple rest client with caching support. By using reflection and a proxy, it allows the user to use a json rest service by simply writing a java interface. It only supports json as data exchange format (by using Gson), and uses OkHttp as HTTP client. You can use it also on Android.
- Declare a java interface
@RestService("http://www.mybookstore.example.com/rest")
public interface BookStoreService {
@GET
@Path("books/{ISBN}")
@Cache
Book getBook(@PathParam("ISBN") String ISBN);
@GET
@Path("books/{ISBN}/reviews")
ReviewSummary[] getRewiewsSummary(@PathParam("ISBN") String ISBN);
@GET
@Path("books/{ISBN}/reviews")
ReviewSummary[] getRewiewsSummary(@PathParam("ISBN") String ISBN,
@QueryParam("from") int from,
@QueryParam("to") int to);
@GET
@Path("books/{ISBN}/reviews/{ID}")
Review getReview(@PathParam("ISBN") String ISBN,
@PathParam("ID") String reviewID);
@POST
@Path("books/{ISBN}/reviews/create")
Review postReview(@HeaderParam("Auth-Token") String token,
@PathParam("ISBN") String ISBN,
Review review);
}- Use the
RestClientFactoryto instantiate the client
BookStoreService service = RestClientFactory.createClient(BookStoreService.class);- Call the service methods
Book book = service.getBook("978-0123745149");
...
ReviewSummary[] summaries = service.getReviewsSummary("978-0321563842", 10, 20);
...
Review review = service.getReview("978-0321349606", "d52387880");
...
Review myReview = ...
Review result = service.postReview(token, "978-0201633610", myReview);
if (result != null) {
...
}- Eventually change client properties
RestClientInterface restClient = (RestClientInterface) service;
restClient.setBaseUrl("http://myotherbookstore.example.com/services");- Callback mechanism for exceptions thrown inside the service implementation
- Callback mechanism to handle HTTP responses not equals to 200
- OAuth support
- Add xml data exchange format
- Add compile time class generation to prevent the use of a proxy and the massive reflection usage (it sounds funny, probably it will go first)
