代码以交互方式工作，但在编织时不起作用

// 定义一个切面
@Aspect
public class LoggingAspect {
    @Before("execution(* com.example.service.*.*(..))")
    public void logBefore(JoinPoint joinPoint) {
        System.out.println("Entering method: " + joinPoint.getSignature().getName());
    }
}

// 目标类
@Service
public class MyService {
    public void doSomething() {
        System.out.println("Doing something...");
    }
}

// 主类
public class Main {
    public static void main(String[] args) {
        ApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
        MyService myService = context.getBean(MyService.class);
        myService.doSomething();
    }
}

// 配置类
@Configuration
@EnableAspectJAutoProxy
@ComponentScan("com.example")
public class AppConfig {
}
