Spring Sleuth - 对 JMS ErrorHandler 的跟踪中断

Spring Sleuth - broken tracing on JMS ErrorHandler

我有一个简单的示例 https://github.com/gtiwari333/sleuth-jms-broken-tracing/tree/master,它使用 Spring Sleuth 和 JMS。

在这里,对 /jms 端点的调用将消息排队,并在 onMessage 方法接收到消息后,我们正在对 /test 进行 GET 调用并抛出 MyException.我们希望跟踪 ID 传递给 ErrorHandler,以便我们在 /jmsonMessage()handleError()/test 之间的日志中看到相同的 traceId端点。

我正在now/How得到错误:

我 运行 应用程序并点击 localhost:8080/jms 端点。在下面的日志中,TraceId 未在 JmsListenerErrorHandler class 中传播,并且为对 /test

的 GET 调用创建了一个新的 TraceId

看起来 JMS 在新线程中处理了 receive/processing 条新消息。 Sleuth 具有必要的“工具”逻辑来拦截 Trace/Span id 并将其传播到 @JmsListener 代码,但它不会传播到 org.springframework.util.ErrorHandler.

代码:

@RestController 和@JmsListener:

@RestController
static class Ctrl {

    @Autowired RestTemplate restTemplate;
    @Autowired JmsTemplate jmsTemplate;

    @GetMapping("/test")
    void test() {
        log.info("test1 called");
    }

    @GetMapping("/jms")
    void jms() {
        log.info("Queuing message ...");
        jmsTemplate.convertAndSend("test-queue", "SOME MESSAGE !!!");
    }

    @JmsListener(destination = "test-queue", concurrency = "5")
    void onMessage(TextMessage message) throws JMSException {
        log.info("JMS message received {}", message.getText());
        restTemplate.getForEntity("http://localhost:8080/test", Void.class); //-->it works
        throw new MyException("Some Error");  //-->it doesn't
    }
    static class MyException extends RuntimeException {
        public MyException(String msg) { super(msg); }
    }
}

错误处理程序:

@Component
static class JmsListenerErrorHandler implements ErrorHandler {

    @Autowired RestTemplate restTemplate;

    @Override
    public void handleError(Throwable t) {
        log.info("handling error by calling another endpoint .."); //1....tracing is lost here
        restTemplate.getForEntity("http://localhost:8080/test", Void.class);
    }
}

JMS 配置:

@Configuration
@EnableJms
static class ActiveMqConfig implements JmsListenerConfigurer {

    @Autowired ErrorHandler jmsListenerErrorHandler;

    @Autowired ConnectionFactory connectionFactory;

    @Override
    public void configureJmsListeners(JmsListenerEndpointRegistrar registrar) {
        registrar.setContainerFactory(containerFactory());
    }

    @Bean
    JmsListenerContainerFactory<?> containerFactory() {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
        factory.setErrorHandler(jmsListenerErrorHandler);
        return factory;
    }
}

我尝试了什么:(使其成为一个完整的 SO 问题)

它在公关中:https://github.com/gtiwari333/sleuth-jms-broken-tracing/pull/1/files 在这里,我尝试使用创建一个由 LazyTraceThreadPoolTaskExecutor 包装的自定义 Executor bean 并尝试将其传递给 JmsListenerContainerFactory

它适用于正常的线程执行,但不适用于 JMS 内容。

executor.execute(() -> log.info("Im inside thread 2")); //it works

有没有人想出如何拦截ErrorHandler来传递TraceId?

关于 @JmsListener 的检测有一个 open issue。所以我猜目前是不支持的。

一个可能的解决方案是在异常中传递Span

@RestController
static class Ctrl {
    @Autowired
    private Tracer tracer;
    // ...
    @JmsListener(destination = "test-queue", concurrency = "5")
    void onMessage(TextMessage message) throws JMSException{
        //..
        throw new MyException("Some Error",tracer.currentSpan()); // <-- pass current span
    }
}

所以你可以在JmsListenerErrorHandler得到它:

@Override
public void handleError(Throwable t) {
    if(t.getCause() instanceof MyException){
        MyException mEx = (MyException) t.getCause();
        log.info("Failing span: {}",mEx.getSpan());
    }
    //...
}

MyException class:

class MyException extends RuntimeException {
    private final Span span;
    public MyException(String msg, Span span) {
        super(msg);
        this.span=span;
    }
    // Getter for the Span
}
