Java Spring重试复合策略不起作用

我正在使用具有以下RetryTemplate配置的模块：

@EnableRetry
@Configuration
public class RetryConfig {

    @Bean
    public RetryTemplate retryTemplate() {
        final FixedBackOffPolicy backOffPolicy = new FixedBackOffPolicy();
        backOffPolicy.setBackOffPeriod(500);

        final SimpleRetryPolicy attemptsPolicy = new SimpleRetryPolicy();
        attemptsPolicy.setMaxAttempts(2);
        final TimeoutRetryPolicy timeoutPolicy = new TimeoutRetryPolicy();
        timeoutPolicy.setTimeout(2000);
        final CompositeRetryPolicy retryPolicy = new CompositeRetryPolicy();
        retryPolicy.setPolicies(new RetryPolicy[] {timeoutPolicy, attemptsPolicy});

        final RetryTemplate template = new RetryTemplate();
        template.setBackOffPolicy(backOffPolicy);
        template.setRetryPolicy(retryPolicy);
        return template;
    }
}

但是TimeoutRetryPolicy（用于CompositeRetryPolicy实例）显然不起作用

我正在注入RetryTemplate以使用SOAP服务，在某些情况下，响应需要10秒以上。但是，通过配置，我认为不应超过4秒（2秒超时*2次尝试）。

提前非常感谢

我遇到了同样的问题，不幸的是无法使用spring重试解决。因此，我实现了自己的泛型类：（gist-link）

它的用途非常简单：

try {
    final int attempts = 2;
    final long timeout = 2000;
    final String foo = new RetryTemplate<String>(attempts, timeout).execute(() -> {
        // Your retryable logic here!
        return "Lorem ipsum";
    });
} catch (RetryException retryExpectedError) {
    // Your logic if the re-attempts is exceeded.
    // Note: RetryException is a simple inheritance of RuntimeException.
}

试试看{
最终int尝试=2；
最终长超时=2000；
最后一个字符串foo=newretrytemplate（尝试，超时）。执行（（）->{
//你的逻辑在这里！
返回“Lorem ipsum”；
});
}捕获（RetryException retryExpectedError）{
//如果超过重新尝试，则返回您的逻辑。
//注意：RetryException是RuntimeException的简单继承。
}

虽然我还没有实现控件回退，但这将是微不足道的。我希望有帮助

首先是测试服务

@Service
public class RetrySoapServiceImpl implements RetryCallback<YourClass, YourException>{
    static private int i = 0;
        @Retryable(
        value = { YourException.class }, 
        maxAttempts = 300 //Just an Example. Try it with 6.
        @Override
        public PartnerWertelistenResponse doWithRetry(RetryContext arg0) throws YourException {
            System.out.println("Attempt "+i);
            i++;
            if (i<300) throw new YourException();
            else {
                System.out.println("No Exception");
                return null;
            }
        }       
}

作品非常感谢你！

RetryTemplate template = new RetryTemplate();
        FixedBackOffPolicy backOffPolicy = new FixedBackOffPolicy();
        backOffPolicy.setBackOffPeriod(5000); //You'll become mesages every 5 Seconds.
        TimeoutRetryPolicy policy = new TimeoutRetryPolicy();
        policy.setTimeout(50000L); //you'll be back in 50 Seconds, so you schould'nt wait 300*5 Sec.
        template.setRetryPolicy(policy); //It's the last point
        template.setBackOffPolicy(backOffPolicy); //It's the time to repeat an attempt

        try {
            YourClass result2 = template.execute(new RetrySoapServiceImpl());
        } catch (YourException e) {
            System.out.println("parent Catch Attempt "+e.getClass().getName());
        }
        System.out.println("ready to return");
