Spring Cloud GateWay 集成 Sentinel 分布式流量控制框架

本文基于 Spring Boot2.1.11.RELEASE, Spring Cloud Greenwich.SR4, Spring Cloud Alibaba2.1.1.RELEASE, Sentinel 1.7.1

首先在网关模块 加入maven依赖, 等待maven 下载依赖

<dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId> </dependency> <dependency> <groupId>com.alibaba.csp</groupId> <artifactId>sentinel-spring-cloud-gateway-adapter</artifactId> <version>1.7.1</version> </dependency> 

作者这边没有指定版本号是因为做了统一的版本处理
然后编写 配置类

import com.alibaba.csp.sentinel.adapter.gateway.sc.SentinelGatewayFilter; import com.alibaba.csp.sentinel.adapter.gateway.sc.exception.SentinelGatewayBlockExceptionHandler; import org.springframework.beans.factory.ObjectProvider; import org.springframework.boot.autoconfigure.AutoConfigureBefore; import org.springframework.cloud.gateway.filter.GlobalFilter; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.core.Ordered; import org.springframework.core.annotation.Order; import org.springframework.http.codec.ServerCodecConfigurer; import org.springframework.web.reactive.result.view.ViewResolver; import java.util.Collections; import java.util.List; /** * Gateway Sentinel 配置 * @author Jeckxu */ @Configuration public class GatewayConfiguration { private final List<ViewResolver> viewResolvers; private final ServerCodecConfigurer serverCodecConfigurer; public GatewayConfiguration(ObjectProvider<List<ViewResolver>> viewResolversProvider, ServerCodecConfigurer serverCodecConfigurer) { this.viewResolvers = viewResolversProvider.getIfAvailable(Collections::emptyList); this.serverCodecConfigurer = serverCodecConfigurer; } @Bean @Order(Ordered.HIGHEST_PRECEDENCE) public SentinelGatewayBlockExceptionHandler sentinelGatewayBlockExceptionHandler() { // Register the block exception handler for Spring Cloud Gateway. return new SentinelGatewayBlockExceptionHandler(viewResolvers, serverCodecConfigurer); } @Bean @Order(Ordered.HIGHEST_PRECEDENCE) public GlobalFilter sentinelGatewayFilter() { return new SentinelGatewayFilter(); } } 

到此, GateWay 模块集成 Sentinel Code工作已经完成!

打开你的Sentinel 控制台, 你会发现相关的接口记录已经在Web中展示
