java – Springboot @retryable没有重试

@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);
    }

我已将以下内容添加到pom.xml中.

<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>

我也试过为@Retryable提供不同的参数组合.

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

谢谢.
