在使用CompletableFuture时,AspectJ可能无法正确地拦截异步方法。为了解决这个问题,请在异步方法中添加@Async注释,并在调用异步方法时使用AspectJ代理对象。以下是一个示例:
@Service
public class MyService {
@Async
public CompletableFuture myMethod() {
// some async code
return CompletableFuture.completedFuture("result");
}
}
@Aspect
@Component
public class MyAspect {
@Around("execution(* com.example.MyService.myMethod(..))")
public Object aroundMyMethod(ProceedingJoinPoint joinPoint) throws Throwable {
// do something before method execution
Object result = joinPoint.proceed();
// do something after method execution
return result;
}
}
@Component
public class MyApp {
@Autowired
private MyAspect myAspect;
public static void main(String[] args) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(MyApp.class);
MyService myService = context.getBean(MyService.class);
MyAspect myAspect = context.getBean(MyAspect.class);
// create a proxy for the service using aspectj
MyService myServiceProxy = (MyService) myAspect.aroundMyMethod(myService);
// call the async method using the proxy
CompletableFuture futureResult = myServiceProxy.myMethod();
// handle the result when it is available
futureResult.thenAccept(result -> {
// do something with the result
});
}
}
