企业官网建设流程全解析

废话不多说直接上代码：

1.依赖：

<dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>31.1-jre</version> </dependency>

2.配置类注册bean：

package com.hmdp.config; import com.google.common.util.concurrent.RateLimiter; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import java.util.concurrent.TimeUnit; @Configuration public class RateLimiterConfig { @Bean("seckillRateLimiter") public RateLimiter seckillRateLimiter() { // 秒杀接口每秒放行 50 个请求（根据实际压测结果调整） // 预热模式：3秒内逐步达到稳定速率，保护冷启动 return RateLimiter.create(50); } }

3.拦截器拦截接口请求：

package com.hmdp.utils; import com.google.common.util.concurrent.RateLimiter; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.stereotype.Component; import org.springframework.web.servlet.HandlerInterceptor; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; @Component public class RateLimitInterceptor implements HandlerInterceptor { private final RateLimiter seckillRateLimiter; public RateLimitInterceptor(@Qualifier("seckillRateLimiter") RateLimiter rateLimiter) { this.seckillRateLimiter = rateLimiter; } @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { // 对秒杀下单接口进行限流判断 if (request.getRequestURI().contains("/voucher-order/seckill/")) { // 非阻塞式获取令牌，立刻返回成功/失败 if (!seckillRateLimiter.tryAcquire()) { response.setStatus(429); response.setContentType("application/json;charset=UTF-8"); response.getWriter().write("{\"code\":429,\"msg\":\"当前请求人数过多，请稍后重试\"}"); return false; }} else { return true; } return true; } }

4.注册拦截器添加白名单：

registry.addInterceptor(rateLimitInterceptor) .addPathPatterns("/voucher-order/seckill/**");

5.apifox做简单压测
