正在尝试配置Sping Boot Retry for Simple Method。当设置maxAttempts = 3时，执行9次。当maxAttempts = 2时，执行4次。下面是我的控制器类。

@GetMapping("/getPendingTrailRenewals")
    public void saveUserSubscription() {
        userSubscriptionService.checkMethod();
    }

这是我配置了重试的服务类

@Override
    @Retryable(retryFor = DatabaseOperationException.class, maxAttempts = 3, backoff = @Backoff(delay = 100))
    public void checkMethod(){
        log.info("checkMethod executed");
        throw new DatabaseOperationException("Testing");
    }

@Configuration
@EnableRetry
public class RetryConfig {
    @Bean
    public RetryConfiguration retryConfiguration() {
        return new RetryConfiguration();
    }
}

根据日志执行的计数方法超出预期。

在这次变更后，运行良好。

@Configuration
public class RetryConfig {
    @Bean
    public RetryConfiguration retryConfiguration() {
        return new RetryConfiguration();
    }
}

删除RetryConfiguration的@Bean，添加@EnableRetry时已自动导入相同的配置类。因此配置加倍。

@Configuration
@EnableRetry
public class RetryConfig { }

当您同时拥有注解和@Bean方法时，您将获得用于重试逻辑的双重代理/拦截器。每个拦截器将执行配置的重试次数，但是内部拦截器将在每次被调用时执行配置的重试次数。
因此，当重试计数为2时，外部拦截器将调用内部拦截器两次，只有在执行每个调用两次之后才会失败。现在，当将数字增加到3时，外部拦截器最终将调用内部拦截器3次，每次调用都会执行3次重试。

java Spring的RepeatMaxAttempts没有行为，并且调用了超过配置的
