一、注解类

@Target({ElementType.METHOD, ElementType.TYPE, ElementType.PACKAGE})
@Retention(RetentionPolicy.RUNTIME)
public @interface TokenPermission {
}

二、切面类

@Aspect
@Component
@Slf4j
public class Permission {
    @Resource
    private RedisTemplate redisTemplate;
    /**
     * 设置切入点
     */
    @Pointcut("@annotation(com.dragonest.aop.TokenPermission)")
    public void tokenPointer() {
    }
    /**
     * 环绕切入
     *
     * @param pjp
     * @return
     */
    @Around("tokenPointer()")
    public Object around(ProceedingJoinPoint pjp) throws Throwable {
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        String token = request.getHeader(CommonConstants.TOKEN);
        Object tokenInfo = redisTemplate.opsForValue().get("redis中token的key");
        if (tokenInfo == null) {
            // 抛出token验证异常统一处理
            throw GlobalException.getInstance(ErrorCodeEnum.TOKEN_EMPTY);
        }
        Object object = pjp.proceed();
        return object;
    }
}
