spring boot+ redis 接口访问频率限制的实现
作者：毅大师
这篇文章主要介绍了spring boot+ redis 接口访问频率限制的实现，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧
生产环境下可以解决的问题：
1.短信验证码请求评率限制（防止抓包短信轰炸）
2.热点数据请求评率限制（防止数据库爆炸）
@Component
public class BlackInterceper implements HandlerInterceptor {
@Autowired
private RedisTemplate<String, Object> redisTemplate;
private Logger log = LoggerFactory.getLogger(this.getClass());
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
response.setHeader("Content-type", "text/html;charset=UTF-8");
String token = request.getHeader(Cons.TOKEN.WECHAT);
String requestURI = request.getRequestURI();
if (StringUtils.isBlank(token)) {
response.setHeader("Content-type", "text/html;charset=UTF-8");
response.getWriter().write(JsonUtils.marshalToString(ReturnResult.build(401, "未授权")));
return false;
}
Integer userId = (Integer) redisTemplate.opsForValue().get(Cons.TOKEN.WECHAT + ":" + token);
log.error("userId={},访问了url={},请求ip={}",token,requestURI, IpUtil.getIpAddress(request));
if(redisTemplate.hasKey("black")){
if(redisTemplate.opsForSet().isMember("black", userId)){
response.getWriter().write(JsonUtils.marshalToString(ReturnResult.build(500, "由于存在恶意攻击你已被限制访问")));
return false;
}
}
Integer count = (Integer)redisTemplate.opsForValue().get("limit:"+token);
if(count==null){
redisTemplate.opsForValue().set("limit:"+token, 1, 60, TimeUnit.SECONDS);
return true;
}else{
if(count>100 && count<150){
response.getWriter().write(JsonUtils.marshalToString(ReturnResult.build(500, "请求太频繁，请稍后再试")));
redisTemplate.opsForValue().increment("limit:"+token, 1);
return false;
}else if(count>=150){
redisTemplate.opsForSet().add("black",userId,2,TimeUnit.DAYS);
response.getWriter().write(JsonUtils.marshalToString(ReturnResult.build(500, "请求太频繁，已经被限制访问")));
//redisTemplate.opsForSet().add("black",token);
return false;
}else{
redisTemplate.opsForValue().increment("limit:"+token, 1);
return true;
}
}
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
// TODO Auto-generated method stub
}
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
throws Exception {
// TODO Auto-generated method stub
}
}
