自定义注解 使用AOP实现用户访问日志

首先编写一个自定义注解，值为操作的内容

/**
 * 系统日志注解
 */
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SysLog {

    String value() default "";
}

/**
 * 系统日志
 */
@Aspect
@Component
public class SysLogAspect {
 定义切面类，切注解
    @Pointcut("@annotation(com.webworld.marlboro.ecp.base.annotation.SysLog)")
    public void logPointCut() {

    }
 环绕切
    @Around("logPointCut()")
    public Object around(ProceedingJoinPoint point) throws Throwable {
        long beginTime = System.currentTimeMillis();
        //执行方法
        Object result = point.proceed();
        //执行时长(毫秒)
        long time = System.currentTimeMillis() - beginTime;

        //保存日志
        saveUserLog(point, time);

        return result;
    }

    private void saveUserLog(ProceedingJoinPoint joinPoint, long time) {
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        Method method = signature.getMethod();

        UserLog userLog = new UserLog();
        SysLog syslog = method.getAnnotation(SysLog.class);
        if (syslog != null) {
            //注解上的描述
            userLog.setOperation(syslog.value());
        }

        //请求的方法名
        String className = joinPoint.getTarget().getClass().getName();
        String methodName = signature.getName();
        // 方法返回值
        AnnotatedType annotatedReturnType = method.getAnnotatedReturnType();
        Type returnType = annotatedReturnType.getType();
        String returnTypeName = returnType.getTypeName();

        //请求的参数
        Object[] args = joinPoint.getArgs();

        userLog.setMethod(returnTypeName + " " + className + "." + methodName + "(" + Arrays.toString(args) + ")");
        try {
            String params = new Gson().toJson(args[0]);
            userLog.setParameters(params);
        } catch (Exception e) {

        }

        //获取request
        HttpServletRequest request = HttpContextUtils.getHttpServletRequest();

        //获取请求类型
        String requestMethod = request.getMethod();
        userLog.setRequestType(requestMethod);

        //获取userAgent
        String userAgent = request.getHeader("User-Agent");
        userLog.setUserAgent(userAgent);

        String requestURI = request.getRequestURI();
        userLog.setUrl(requestURI);

        //设置IP地址
        userLog.setIp(IPUtils.getIpAddr(request));

        Long userId = NumberUtils.createLong(StringUtils.valueOf(HttpContextUtils.getAttribute(SessionConstant.USER_ID)));
        Long shopId = NumberUtils.createLong(StringUtils.valueOf(HttpContextUtils.getAttribute(SessionConstant.SHOP_ID)));

        if (userId == null) {
            String weChatOpenId = StringUtils.valueOf(HttpContextUtils.getAttribute(SessionConstant.WE_CHAT_OPEN_ID));
            if (StringUtils.isNotBlank(weChatOpenId)) {
                User user = userService.findByWeChatOpenId(weChatOpenId);
                if (user != null) {
                    userId = user.getId();
                    Shop shop = shopService.findByUserId(userId);
                    shopId = shop == null ? null : shop.getId();
                }
            }
        }
        userLog.setUserId(userId);
        userLog.setShopId(shopId);

        userLog.setTime(time);
        userLog.setRequestDate(new Date());

        //保存系统日志
        userLogService.save(userLog);
    }
}

@SysLog("修改当前用户信息")
    @PutMapping(value = "/current/info")
    public Result updateUserInfo(@RequestBody UserVo userVo) throws ParseException {

}

控制层加上SysLog注解，觉可以实现用户日志的记录了
