Springboot @retryable not retrying

Question

The following code is not retrying. What am I missing?

@EnableRetry
@SpringBootApplication
public class App implements CommandLineRunner
{
    .........
    .........


    @Retryable()
    ResponseEntity<String> authenticate(RestTemplate restTemplate, HttpEntity<MultiValueMap<String, String>> entity) throws Exception
    {
        System.out.println("try!");
        throw new Exception();
        //return restTemplate.exchange(auth_endpoint, HttpMethod.POST, entity, String.class);
    }

I have added the following to the pom.xml.

    <dependency>
        <groupId>org.springframework.retry</groupId>
        <artifactId>spring-retry</artifactId>
        <version>1.1.2.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-aop</artifactId>
    </dependency>

I also tried providing different combinations of arguments to @Retryable.

@Retryable(maxAttempts=10,value=Exception.class,backoff=@Backoff(delay = 2000,multiplier=2))

Thanks.

Answer 1

In spring boot 2.0.2 Release, I have observed that the @Retryable is not working if you have retryable and called method in same class. On debugging found that the pointcut is not getting built properly. For now, the workaround for this problem is that we need to write the method in a different class and call it.

Working Example could be found here.

Answer 2

For the @Retryable annotation on the method to be discovered it needs to be called correctly from an initialised context. Is the method invoked from a bean from the spring context or called by other means?

If testing this is your runner using the SpringJunit4ClassRunner?
