I want my RetryTemplate to have a delay of 300000 ms - 5 minutes multiplied by 1.1 per try. However, it only delays the next attempt by 30 seconds. Here's a simplified example:
@Service
public class Foo {
private static final Logger log = Logger.getLogger(Foo.class);
@Retryable(value = Exception.class,
backoff = @Backoff(delay = 300000, multiplier = 1.1))
public void run() throws Exception {
new Bar().run();
}
@Recover
void recover(Exception e) {
log.error("e", e);
}
}
public class Bar {
private static final Logger log = Logger.getLogger(Bar.class);
public void run() throws Exception{
log.info("hier");
throw new Exception();
}
}
@Bean
CommandLineRunner runner() {
return (String[] a) -> {
scheduler.schedule(() -> {
try {
retryTemplate.execute(arg -> {
foo.run();
return null;
});
} catch (Exception e) {
}
}, 1 , TimeUnit.SECONDS);
};
}
The logs are made on these times:
2017-03-17 13:25:08.439 INFO 6500 --- [
2017-03-17 13:25:38.439 INFO 6500 --- [
2017-03-17 13:26:08.440 INFO 6500 --- [
2017-03-17 13:26:08.444 ERROR 6500 --- [
It doesn't make a difference if I use it with or without the scheduler (which is there because the original code needs the initial delay.)
Now if I add a maxDelay to the @Backoff
@Backoff(delay = 300000, multiplier = 1.1, maxDelay = 1000000000)
It works exactly as intended - firing after 5 minutes, then after 5*1.1 minutes and so on. However reading the javadoc for @Backoff - maxDelay, it says it defaults to 0 and is ignored if less than delay
/**
* The maximimum wait (in milliseconds) between retries. If less than the
* {@link #delay()} then ignored.
*
* @return the maximum delay between retries (default 0 = ignored)
*/
long maxDelay() default 0;
Is there anything I didn't understand? It seems like the maxDelay defaults to 30 seconds, which is quite different from what the javadoc explains.
Used spring-retry version is 1.1.3
