使用正则表达式指定Zuul的路由匹配规则

一 新建项目microservice-gateway-zuul-reg-exp

二 修改ZuulApplication

package com.itmuch.cloud.study;

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;

@SpringBootApplication
@EnableZuulProxy
public class ZuulApplication {

  @Bean
  public PatternServiceRouteMapper serviceRouteMapper() {
    // 调用构造函数PatternServiceRouteMapper(String servicePattern, String routePattern)
    // servicePattern指定微服务的正则
    // routePattern指定路由正则
    return new PatternServiceRouteMapper("(?^.+)-(?v.+$)", "${version}/${name}");
  }

  public static void main(String[] args) {
    SpringApplication.run(ZuulApplication.class, args);
  }
}

三 修改microservice-provider-user微服务的配置

server:
  port: 8000
spring:
  application:
    name: microservice-provider-user-v1
  jpa:
    generate-ddl: false
    show-sql: true
    hibernate:
      ddl-auto: none
  datasource:                           # 指定数据源
    platform: h2                        # 指定数据源类型
    schema: classpath:schema.sql        # 指定h2数据库的建表脚本
    data: classpath:data.sql            # 指定h2数据库的数据脚本
logging:                                # 配置日志级别，让hibernate打印出执行的SQL
  level:
    root: INFO
    org.hibernate: INFO
    org.hibernate.type.descriptor.sql.BasicBinder: TRACE
    org.hibernate.type.descriptor.sql.BasicExtractor: TRACE
eureka:
  client:
    healthcheck:
      enabled: true
    serviceUrl:
      defaultZone:http://localhost:8761/eureka/
      #defaultZone: http://user:password123@localhost:8761/eureka/
  instance:
    prefer-ip-address: true

四 测试

1 启动Eureka

2 启动用户微服务

3 启动zuul

4 浏览器输入 http://localhost:8040/v1/microservice-provider-user/1

5 说明 

通过这段代码即可实现将诸如microservice-provider-user-v1这个微服务，映射到/v1/microservice-provider-user/** 这个路径。
