A simple Spring Retry configuration example

SpringRetry.groovy

@Bean
RetryTemplate retryTemplate() {
  RetryTemplate retryTemplate = new RetryTemplate()

  FixedBackOffPolicy fixedBackOffPolicy = new FixedBackOffPolicy()
  fixedBackOffPolicy.setBackOffPeriod(1000l)
  retryTemplate.setBackOffPolicy(fixedBackOffPolicy)

  SimpleRetryPolicy retryPolicy = new SimpleRetryPolicy()
  retryPolicy.setMaxAttempts(2)
  retryTemplate.setRetryPolicy(retryPolicy)

  return retryTemplate
}


// example usage (could be replaced with lambda)
retryTemplate.execute(new RetryCallback<Void, RuntimeException>() {
    @Override
    public Void doWithRetry(RetryContext ctx) {
        someService.fetchData();
        ...
    }
});
