我有几个动态卡夫卡消费者(基于部门ID等),你可以找到下面的代码。
基本上,我想记录每一次的时间。
onMessage()
方法调用,因此我创建了
@LogExecutionTime
方法自定义自定义注释并将其添加到
onMessage()
方法。
但是我的
logExecutionTime()
属于
LogExecutionTimeAspect
即使我的电话
onMessage()
当有关于主题的消息时调用,其他一切都正常工作。
你能帮我弄清楚我遗漏了什么吗
LogExecutionTimeAspect
上课让它开始工作?
日志执行时间:
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface LogExecutionTime {
}
LogExecutionTimeAspect类:
@Aspect
@Component
public class LogExecutionTimeAspect {
@Around("within(com.myproject..*) && @annotation(LogExecutionTime)")
public Object logExecutionTime(ProceedingJoinPoint joinPoint) throws Throwable {
long startTime = System.currentTimeMillis();
Object object = joinPoint.proceed();
long endTime = System.currentTimeMillis();
System.out.println(" Time taken by Listener ::"+(endTime-startTime)+"ms");
return object;
}
}
部门信息消费者类别:
@Component
public class DepartmentsMessageConsumer implements MessageListener {
@Value(value = "${spring.kafka.bootstrap-servers}" )
private String bootstrapAddress;
@PostConstruct
public void init() {
Map<String, Object> consumerProperties = new HashMap<>();
consumerProperties.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG,
bootstrapAddress);
consumerProperties.put(ConsumerConfig.GROUP_ID_CONFIG, "DEPT_ID_HERE");
ContainerProperties containerProperties =
new ContainerProperties("com.myproj.depts.topic");
containerProperties.setMessageListener(this);
DefaultKafkaConsumerFactory<String, Greeting> consumerFactory =
new DefaultKafkaConsumerFactory<>(consumerProperties,
new StringDeserializer(),
new JsonDeserializer<>(Department.class));
ConcurrentMessageListenerContainer container =
new ConcurrentMessageListenerContainer<>(consumerFactory,
containerProperties);
container.start();
}
@Override
@LogExecutionTime
public void onMessage(Object message) {
ConsumerRecord record = (ConsumerRecord) message;
Department department = (Department)record.value();
System.out.println(" department :: "+department);
}
}
应用程序启动程序类:
@SpringBootApplication
@EnableKafka
@EnableAspectJAutoProxy
@ComponentScan(basePackages = { "com.myproject" })
public class ApplicationLauncher extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(ApplicationLauncher.class, args);
}
}
编辑:
我试过了
@EnableAspectJAutoProxy(exposeProxy=true)
,但不起作用。
