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.
