3.ProductServiceZuulApplication

@SpringBootApplication
@EnableZuulProxy            //网关
@EnableEurekaClient
@EnableDiscoveryClient
public class ProductServiceZuulApplication {
    public static void main(String[] args) {
        int port = 8040;
        if(!NetUtil.isUsableLocalPort(port)) {
            System.err.printf("端口%d被占用了，无法启动%n", port );
            System.exit(1);
        }
        new SpringApplicationBuilder(ProductServiceZuulApplication.class).properties("server.port=" + port).run(args);

    }
}
