This article mainly introduces the relevant knowledge of how springcloud integrates gateway to achieve the gateway. The content is detailed and easy to understand, easy to operate, and has a certain reference value. I believe you will gain something after reading this article on how to integrate springcloud and gateway to realize the gateway. Let's take a look.

1. Project catalog:

Create the project gateway as the parent class

two。 Code implementation:

Parent class dependency

Org.springframework.boot spring-boot-starter-parent 2.6.2 com.cxh gateway 0.0.1-SNAPSHOT gateway Demo project for Spring Boot pom 8 2021.1 2021.0.0 org.springframework.cloud spring-cloud-dependencies $ {spring-cloud-dependencies.version} pom import com.alibaba.cloud spring-cloud-alibaba-dependencies ${spring-cloud-alibaba-dependencies.version} pom import

Create a module project gateway-client

Add dependency

Com.cxh gateway 0.0.1-SNAPSHOT com.cxh gateway-client 0.0.1-SNAPSHOT gateway-client Demo project for Spring Boot 1.8 org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-test Test org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-test test org.springframework.cloud spring-cloud-starter-alibaba-nacos-discovery 0.2.1.RELEASE Org.springframework.cloud spring-cloud-starter-openfeign org.springframework.boot spring-boot-starter-web

Yml configuration

Server: port: 8002spring: application: name: gateway-client # Service name profiles: active: dev # Environment Settings cloud: nacos: discovery: server-addr: 127.0.0.1 discovery 8848 # nacos Service Registration

Control layer

@ RestControllerpublic class ClientController {@ Value ("${server.port}") private String port; @ RequestMapping ("/ index") public String index () {return "gateway-client Port:" + port;}}

Start the class to add comments

@ SpringBootApplication@EnableDiscoveryClientpublic class GatewayClientApplication {public static void main (String [] args) {SpringApplication.run (GatewayClientApplication.class, args);}}

Create a module project gateway-service

Add dependency

Com.cxh gateway 0.0.1-SNAPSHOT com.cxh gateway-service 0.0.1-SNAPSHOT gateway-service Demo project for Spring Boot 1.8 org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-test Test org.springframework.cloud spring-cloud-starter-gateway 3.0.4 com.alibaba.cloud spring-cloud-starter-alibaba-nacos-discovery com.alibaba.cloud spring-cloud-starter-alibaba-nacos-config Org.springframework.cloud spring-cloud-starter-feign 1.4.3.RELEASE org.springframework.cloud spring-cloud-loadbalancer org.springframework.cloud spring-cloud-starter-netflix-hystrix 2.2.10.RELEASE

Yml configuration

Server: port: 8001spring: application: name: gateway-service # Service name profiles: active: dev # Environment Settings cloud: gateway: routes: # transparent transfer Service-id: gateway-client # Settings routing id uri: lb://gateway-client # setting url lb://nacos Service Registration name for routes predicates:-Path=/ Client/** # path matching rule filters:-StripPrefix=1

Cross-domain configuration

@ Configurationpublic class CorsConfig {@ Bean public CorsWebFilter corsFilter () {CorsConfiguration config = new CorsConfiguration (); config.addAllowedMethod ("*"); config.addAllowedOrigin ("*"); config.addAllowedHeader ("*"); UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource (new PathPatternParser ()); source.registerCorsConfiguration ("/ *", config); return new CorsWebFilter (source);}} 3. Achieve results:

After starting nacos, start the gateway-client, gateway-service project, and open the browser http://localhost:8001/client/index

Return information: gateway-client port: 8002
