Spring Retry provides an abstraction around retrying failed operations, with an emphasis on declarative control of the process and policy-based behaviour that is easy to extend and customize. For instance, you can configure a plain POJO operation to retry if it fails, based on the type of exception, and with a fixed or exponential backoff.

The newest version!

/**
 * Annotation for a method invocation that is a recovery handler. A suitable recovery
 * handler has a first parameter of type Throwable (or a subtype of Throwable) and a
 * return value of the same type as the @Retryable method to recover from.
 * The Throwable first argument is optional (but a method without it will only be called
 * if no others match). Subsequent arguments are populated from the argument list of the
 * failed method in order.
