gateway实战,gateway连接

Gateway 是一个异步的的路由框架

他的性能高于zuul(zuul是一个线程阻塞的路由框架),
这里贴出gateway的详细介绍GateWay介绍

先创建工程,创建好之后引入依赖

<dependencies> <!--gateway--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-gateway</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies>

== 引入依赖的时候有一个坑,sprint-boot-starter-web这个依赖是不能够引入的,引入的话getway就启动不了==

启动类 @SpringBootApplication@EnableDiscoveryClientpublic class GetWay { public static void main(String[] args) { SpringApplication.run(GetWay.class, args); }} 在gateway当中配置路由有两种方式,第一种是通过yml配置文件的方式配置路由,第二种是通过配置类的方式来配置路由

第一种-> yml

server: port: 8001spring: application: name: get-way cloud: gateway: discovery: locator: enabled: true lower-case-service-id: true routes: - id: nacos-getway-provider uri: lb://cuiter-user // lb://是指当前注册中心下 后面的是微服务的名字 predicates: - Path=/** nacos: discovery: server-addr: localhost:8848

第二种,配置类

@Configurationpublic class GetWayConfig { @Bean public RouteLocator customRouteLocator(RouteLocatorBuilder routeLocatorBuilder) { RouteLocatorBuilder.Builder routes = routeLocatorBuilder.routes(); routes.route("provider-user", r -> r.path("/findAll").uri("http://www.baidu.com")).build(); return routes.build(); }}

顺便说一下 ,我用的注册中心是阿里的nacos
