Spring AOP 记录请求 Controller 中的方法

注意 @AfterReturning 和 @AfterThrowing 的用法，一个用来对返回值进行处理，
一个对异常进行处理

@Slf4j
@Aspect
@Component
public class ControllerAspect {


  @Pointcut(value = "execution(* com.magic.platform.business.*.controller..*.*(..))")
  public void controllerMethod() {}

  /**
   * 方法执行前
   * @param jp
   */
  @Before("controllerMethod()")
  public void controllerMethodBefore(JoinPoint jp) {
    try {
      String targetClassName = jp.getTarget().getClass().getName();
      String methodName = jp.getSignature().getName();
      String args = Arrays.toString(jp.getArgs());
      // 获取代理目标类自己的 logger
      Logger logger = LoggerFactory.getLogger(targetClassName);

      logger.info(">>>：{}.{}({}) begin", targetClassName, methodName, args.substring(1, args.length() - 1));
    } catch (Exception e) {
      log.error("ControllerAspect.controllerMethodBefore exception:", e);
    }

  }


  /**
   * 方法执行后
   * @param jp
   */
  @After("controllerMethod()")
  public void controllerMethodAfter(JoinPoint jp) {
    try {
      String targetClassName = jp.getTarget().getClass().getName();
      String methodName = jp.getSignature().getName();
      String args = Arrays.toString(jp.getArgs());
      // 获取代理目标类自己的 logger
      Logger logger = LoggerFactory.getLogger(targetClassName);

      logger.info(">>>：{}.{}({}) end", targetClassName, methodName, args.substring(1, args.length() - 1));
    } catch (Exception e) {
      log.error("ControllerAspect.controllerMethodAfter exception:", e);
    }

  }

  /**
   * 方法异常处理 FIXME: 注意避免与 ExceptionHandler 重复处理异常
   * @param jp
   * @param exception
   */
  @AfterThrowing(value = "controllerMethod()", throwing = "exception")
  public void controllerMethodAfterThrowing(JoinPoint jp, Throwable exception) {

    try {
      String targetClassName = jp.getTarget().getClass().getName();
      String methodName = jp.getSignature().getName();
      String args = Arrays.toString(jp.getArgs());
      // 获取代理目标类自己的 logger
      Logger logger = LoggerFactory.getLogger(targetClassName);

      logger.info(">>>：{}.{}({}) exception: {}", targetClassName, methodName, args.substring(1, args.length() - 1), exception.getMessage());
    } catch (Exception e) {
      log.error("ControllerAspect.controllerMethodAfter exception:", e);
    }
  }

  /**
   * 方法返回
   * @param joinPoint
   * @param object
   */
  @AfterReturning(value = "controllerMethod()", returning = "object")
  public void controllerMethodAfterReturning(JoinPoint joinPoint, Object object) {
    // 使用 RequestContextHolder 获取 request
    ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
    HttpServletRequest request = requestAttributes.getRequest();

    if (object instanceof ResponseModel) {
      ((ResponseModel) object).setTimestamp(new Date());
      ((ResponseModel) object).setPath(request.getRequestURI());
    }
  }

//  @Around("controllerMethod()")
//  public void controllerMethodAround(ProceedingJoinPoint jp) {
//
//  }
}

切点的写法：切一个类中的所有的方法
