SpringAOP中基于注解实现通用日志打印方法详解

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface OwnLog {
    String value() default "BaseController";
}

@Aspect
@Component
@Slf4j
public class LogAspect {
    @Before(value = "@annotation(ownLog)")
    public void before(JoinPoint point, OwnLog ownLog) {
        //point.getArgs()获取请求参数
        log.info("服务{}调用开始,请求参数:{}", ownLog.value(), JSONObject.toJSONString(point.getArgs()));
    }
    @Around(value = "@annotation(ownLog)")
    public Object around(ProceedingJoinPoint point, OwnLog ownLog) {
        Object result = null;
        String name = ownLog.value();
        long start = System.currentTimeMillis();
        try {
            result = point.proceed();
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        } finally {
            long end = System.currentTimeMillis();
            log.info(String.format("服务%s,耗时:%dms", name, (end - start)));
        }
        return result;
    }
    //设置rvt为返回参数
    @AfterReturning(value = "@annotation(ownLog)", returning = "rvt")
    public void afterReturning(JoinPoint point, OwnLog ownLog, Object rvt) {
        log.info("服务{}调用结束，response:{}", ownLog.value(), JSONObject.toJSONString(rvt));
    }
}

@OwnLog("sendMsg")
    @Idempotent
    @ApiOperation(value = "消息推送")
    @PostMapping(value = "/sendMsg")
    public BaseResp sendMessage(@ModelAttribute UserMsgHistoryDTO userMsgHistoryDTO) {
        userMsgHistoryService.sendMessage(findCurrentUser(), userMsgHistoryDTO);
        addUserLog(LOG_TYPE_USER, "用户消息推送", JSON.toJSONString(userMsgHistoryDTO));
        return new BaseResp<>(ResultStatus.SUCCESS);
    }
