Springboot中自带依赖
1.创建一个SellerAuthorizeAspect类,打上标签@Aspect和@Component
@Aspect @Component @Slf4j public class SellerAuthorizeAspect { }
2.设置切点,这个注解的意思是拦截所有controller中Seller*开头的类的方法但是不拦截SellerUserController中的方法
@Pointcut("execution(public * com.xiong.sell.controller.Seller*.*(..))" +
" && !execution(public * com.xiong.sell.controller.SellerUserController.*(..))")
public void verify() {
}
3.设置拦截后的操作,这里可以直接处理,也可以抛出一个异常来,然后拦截处理
@Before("verify()")
public void doVerify() {
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
HttpServletRequest request = attributes.getRequest();
//查询cookie
Cookie cookie = CookieUtil.get(request, CookieConstant.TOKEN);
if (cookie == null) {
log.warn("【登录校验】 cookie中没有token");
throw new SellerAuthorizeException();
}
//查询redis
String tokenValue = redisTemplate.opsForValue().get(String.format(RedisConstant.TOKEN_PREFIX, cookie.getValue()));
if(StringUtils.isEmpty(tokenValue)){
log.warn("【登录校验】 redis中没有token");
throw new SellerAuthorizeException();
}
}
