@Retryable似乎没有像下面的sphRemoteCall那样在第二级方法上工作.我看到创建了一个代理,但它永远不会在失败时重试.
一旦我将@Retryable移动到第一级方法(如getSubscriberAccount),它就开始工作了.
示例如下：
@Service
public class SphIptvClient extends WebServiceGatewaySupport {
//Works over here
@Retryable(maxAttempts=3,backoff=@Backoff(delay=100))
public GetSubscriberAccountResponse getSubscriberAccount(String loginTocken,String billingServId) {
GetSubscriberAccountResponse response = (GetSubscriberAccountResponse) sphRemoteCall(sphIptvEndPoint,getSubAcc,"xxxxx");
return response;
}
/*
* Retryable is not working on the 2nd level methods in the bean.
* It works only with methods which are called directly from outside
* if there is 2nd level method,like this,Retryable is not working.
*/
//@Retryable
private Object sphRemoteCall(String uri,Object requestPayload,String soapAction) {
log.debug("Calling the sph for uri:{} and soapAction:{}",uri,soapAction);
return getWebServiceTemplate().marshalSendAndReceive(uri,requestPayload,new SoapActionCallback(soapAction));
}
}
@Configuration
@EnableRetry
public class SphClientConfig {
@Bean
public SphIptvClient sphIptvClient() {
SphIptvClient client = new SphIptvClient();
return client;
}
}
所以这是一个超级迟到的答案,但由于我刚刚来到这里遇到同样的问题(再次,多年前与交易摔跤),我将提供一个更加充实的解决方案,希望有人会发现它有用.可以说@M. Deinum的诊断是正确的.
在上面的例子中,并且为了解释Understanding AOP proxies,SphIptvClient获得自动装配的任何地方都将被赋予对Spring Retry在处理@EnableRetry时将创建的代理的引用：
“The @EnableRetry annotation creates proxies for @Retryable beans” – 07004
一旦调用了getSubscriberAccount并且执行已经通过代理并进入对象的@Service实例,就不会知道对代理的引用.因此,调用sphRemoteCall就好像根本没有@Retryable一样.
您可以通过以允许getSubscriberAccount调用代理编辑的sphRemoteCall的方式对代码进行移植来处理框架,这需要新的接口和类实现.
例如：
public interface SphWebService {
Object sphRemoteCall(String uri,String soapAction);
}
@Component
public class SphWebServiceImpl implements SphWebService {
@Retryable
public Object sphRemoteCall(String uri,String soapAction) {
log.debug("Calling the sph for uri:{} and soapAction:{}",soapAction);
return getWebServiceTemplate().marshalSendAndReceive(uri,new SoapActionCallback(soapAction));
}
}
@Service
public class SphIptvClient extends WebServiceGatewaySupport {
@Autowired
SphWebService sphWebService;
@Retryable(maxAttempts=3,backoff=@Backoff(delay=100))
public GetSubscriberAccountResponse getSubscriberAccount(String loginTocken,String billingServId) {
GetSubscriberAccountResponse response = (GetSubscriberAccountResponse) this.sphWebService.sphRemoteCall(sphIptvEndPoint,"xxxxx");
return response;
}
}
@Configuration
@EnableRetry
public class SphClientConfig {
// the @Bean method was unnecessary and may cause confusion.
// @Service was already instantiating SphIptvClient behind the scenes.
}
