Zuul使用正則表示式指定路由規則

EurekaApplication類

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.cloud.netflix.zuul.filters.discovery.PatternServiceRouteMapper;
import org.springframework.context.annotation.Bean;

@EnableZuulProxy
@SpringBootApplication  //開啟啟動程式入口類
public class EurekaApplication {
  public static void main(String[] args) {
    SpringApplication.run(EurekaApplication.class, args);
  }
  
  /**
   * Zuul使用正則表示式指定路由規則
   * 您可以使用regexmapper提供serviceId和路由之間的約定。它使用名為組的正則表示式從serviceId中提取變數，並將其注入到路由模式中。
   * @return
   */
  @Bean
  public PatternServiceRouteMapper serviceRouteMapper() {
      return new PatternServiceRouteMapper(
          "(?<name>^.+)-(?<version>v.+$)",
          "${version}/${name}");
  }
}
 

application.yml配置

server:
  port: 8040
spring:
  application:
    name: spring-cloud-zuul-api-gateway-reg
eureka:
  client:
    serviceUrl:
      defaultZone: http://user:[email protected]:8761/eureka
  instance:
    prefer-ip-address: true
    
#此處主要是通過正則表示式定義路由規則：
#比如：此處路由到使用者微服務，改下使用者微服務appliaction.name為：spring-cloud-user-v1
#那麼訪問的路徑就為：http://10.138.5.48:8040/v1/spring-cloud-user/user/1
