How to enable Spring retry using version Spring Retry of 1.0.3?

Question

To enable Spring retry one can either enable retry in Java annotation: @EnableRetry within Configuration or specify retry in an XML configuration file:

<context:annotation-config />
<aop:aspectj-autoproxy />
<bean class="org.springframework.retry.annotation.RetryConfiguration" />

Both specification are based on …annotation.RetryConfiguration that started only from the version 1.1.2. How to enable retry in XML configuration in the previous versions? Due to compatibility issues I cannot use version 1.1.2. The retry configuration is as follows:

<aop:config>
    <aop:pointcut id="retrySave"
        expression="execution( * sfweb.service.webServiceOrders.WsOrderCreationServiceImpl.saveLedger(..))" />
    <aop:advisor pointcut-ref="retrySave" advice-ref="retryAdvice"
        order="-1" />
</aop:config>

<bean id="retryAdvice"
    class="org.springframework.retry.interceptor.RetryOperationsInterceptor">
</bean>

Spring Retry 1.0.3 did not have AspectJ based AOP support. Therefore, aspect-style retries will not work with that version. Instead, retryable code needs to be wrapped inside an instance of a RetryCallback. The generic approach is as follows:

1. Create a RetryTemplate

SimpleRetryPolicy simpleRetryPolicy = new SimpleRetryPolicy();
simpleRetryPolicy.setMaxAttempts(maxAttempts);

FixedBackOffPolicy fixedBackOffPolicy = new FixedBackOffPolicy();
fixedBackOffPolicy.setBackOffPeriod(backOffPeriod);

RetryTemplate retryTemplate = new RetryTemplate();
retryTemplate.setBackOffPolicy(fixedBackOffPolicy);
retryTemplate.setRetryPolicy(simpleRetryPolicy);

2. Wrap the retryable code in a RetryCallback

class FailureProneOperation implements RetryCallback<Void> {
  public void doWithRetry(RetryContext context) throws Exception {
    ...
  }
}

3. Execute the retryable code

retryTemplate.execute(new FailureProneOperation())

So, if I have a method saveLedger that is called inside a class method- where it should be fitted? – Alex Mar 05 '16 at 11:52

`doWithRetry(...) { saveLedger(...); }`. – manish Mar 05 '16 at 13:21
How to pass the parameter to saveLedger() – Alex Mar 08 '16 at 15:11
You could expose properties on the wrapper class `FailureProneOperation` on which you can set all the contextual data. Your proposal in the answer below will also work. – manish Mar 09 '16 at 03:23

In addition to the posted answer we need also a code to pass parameters for retryable operations. This can be done in the FailureProneOperation constructor:

public FailureProneOperation(OrderSkuLedger orderSkuLedger) {
    this.orderSkuLedger = orderSkuLedger;
}
