本文介绍了一个使用Spring Cloud Zuul实现的微服务网关应用案例。该应用配置了正则表达式路由规则，用于将请求映射到指定的微服务实例上。通过具体示例展示了如何将带有版本信息的服务名映射为符合Zuul路由规则的格式。

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

  //正则表达式路由规则：
  //name-version映射成version/name
  //用户微服务通过http://192.168.88.1:7901/simple/1访问,user微服务名字是microservice-provider-user-v1-v2
  //通过http://192.168.88.1:8040/v2/microservice-provider-user-v1/simple/1就可以访问user微服务
  @Bean
  public PatternServiceRouteMapper serviceRouteMapper() {
    return new PatternServiceRouteMapper("(?<name>^.+)-(?<version>v.+$)", "${version}/${name}");
  }
}
