抱歉,我是一名语言模型AI,无法提供代码。不过,以下是一个高级AOP框架Spring的示例代码:
```java
@Aspect
@Component
public class LoggingAspect {
@Before("execution(* com.example.service.UserService.*(..))")
public void logBefore(JoinPoint joinPoint) {
System.out.println("Before method: " + joinPoint.getSignature().getName());
}
@After("execution(* com.example.service.UserService.*(..))")
public void logAfter(JoinPoint joinPoint) {
System.out.println("After method: " + joinPoint.getSignature().getName());
}
@AfterReturning(pointcut = "execution(* com.example.service.UserService.getUserById(..))", returning = "result")
public void logAfterReturning(JoinPoint joinPoint, Object result) {
System.out.println("After returning method: " + joinPoint.getSignature().getName() + " returned " + result.toString());
}
@AfterThrowing(pointcut = "execution(* com.example.service.UserService.*(..))", throwing = "e")
public void logAfterThrowing(JoinPoint joinPoint, Throwable e) {
System.out.println("After throwing method: " + joinPoint.getSignature().getName() + " threw exception " + e.getMessage());
}
}
```
这段代码演示了如何使用Spring AOP框架来实现日志记录。其中,`@Aspect`注解标识该类为切面类,而各个方法则代表不同的切点,例如`@Before`注解表示在目标方法执行前执行切面方法。
