Description
The Restler library automatically generates a client for a web service at run time, by analyzing the respective annotated Spring controller interface. Restler may help you remove HTTP-specific boilerplate from your integration tests, microservices and third-party HTTP API clients.

- Custom authentication, authorization and errors mapping strategies
- Support of form-based, http basic, cookie-based and generic header-based authentication
- Support of async controllers through methods returning

Simple Usage Example
Suppose you have the following interface on the server:
/**
* An annotated Spring controller interface
*/
@Controller
@RequestMapping("greeter")
public interface Greeter {
@RequestMapping("greetings/{language}")
String getGreeting(@PathVariable String language, @RequestParam(defaultValue = "Anonymous") String name);
}
Then in your client you can invoke the getGreeting method of the remote service using the following code snippet:
Service service = new Restler("https://www.example.com/api", new SpringMvcSupport()).build();
Greeter greeter = service.produceClient(Greeter.class);
String greeting = greeter.getGreeting("en","Buddy"); // the result of https://www.example.com/api/greeter/greetings/en?name=Buddy call
