Interface BeforeRetryHandler

All Known Implementing Classes:
BeforeRetry.DEFAULT
public interface BeforeRetryHandler
For each retry attempt, a new instance of the handler is created by the CDI container. The instance is created before the handle(ExecutionContext) method is called, and after it finishes, the instance is destroyed. The implementation class can declare injection points, lifecycle callbacks and so on.

Usage

 @ApplicationScoped
 public class MyService {
     @Inject
     OtherService otherService;

     @Retry
     @BeforeRetry(MyBeforeRetry.class)
     String doSomething() {
         return otherService.hello();
     }
 }

 public class MyBeforeRetry implements BeforeRetryHandler {
     @Inject
     OtherService otherService;

     void handle(ExecutionContext context) {
         otherService.reset();
     }
 }
