Spring Retry provides some simple general purpose implementations of stateless RetryPolicy, for example a `SimpleRetryPolicy`, and the `TimeoutRetryPolicy` used in the example above.
The `SimpleRetryPolicy` just allows a retry on any of a named list of exception types, up to a fixed number of times. It also has a list of "fatal" exceptions that should never be retried, and this list overrides the retryable list so that it can be used to give finer control over the retry behavior:
The `SimpleRetryPolicy` just allows a retry on any of a named list of exception types, up to a fixed number of times:
```java
SimpleRetryPolicy policy = new SimpleRetryPolicy();
// Set the max attempts including the initial attempt before retrying
policy.setMaxAttempts(5);
// Retry on all exceptions (this is the default)
// and retry on all exceptions (this is the default):
SimpleRetryPolicy policy = new SimpleRetryPolicy(5, Collections.singletonMap(Exception.class, true));
policy.setRetryableExceptions(new Class[] {Exception.class});
// ... but never retry IllegalStateException
policy.setFatalExceptions(new Class[] {IllegalStateException.class});
// Use the policy...
RetryTemplate template = new RetryTemplate();
