修改办法

方法一：适用于xml配置dubbo的方案。

    <dubbo:registry  id="registry1" address="zookeeper://localhost:2181" timeout="25000"/>

或者

 <dubbo:config-center timeout="25000"/>

方法二：适用于api配置dubbo的方案。

    private static void startWithBootstrap() {
        ServiceConfig<DemoServiceImpl> serviceServiceConfig = new ServiceConfig<>();
        serviceServiceConfig.setInterface(DemoService.class);
        serviceServiceConfig.setRef(new DemoServiceImpl());
        DubboBootstrap bootstrap = DubboBootstrap.getInstance();
        bootstrap.application(new ApplicationConfig("dubbo-one-api-provider"))
                .registry(new RegistryConfig("zookeeper://localhost:2181?timeout=25000"))
                .service(serviceServiceConfig)
                .start()
                .await();

    }

    private static void startWithExport() throws InterruptedException {
        ServiceConfig<DemoServiceImpl> service = new ServiceConfig<>();
        service.setInterface(DemoService.class);
        service.setRef(new DemoServiceImpl());
        service.setApplication(new ApplicationConfig("dubbo-demo-api-provider"));
        service.setRegistry(new RegistryConfig("zookeeper://localhost?timeout=25000"));
        service.export();

        System.out.println("dubbo service started");
        new CountDownLatch(1).await();
    }

方法三：适用于注解配置的。

    @Configuration
    @EnableDubbo(scanBasePackages = "com.rsw")
    @PropertySource("classpath:/spring/dubbo_provider.properties")
    static class ProviderConfiguration {
        @Bean
        public RegistryConfig registryConfig() {
            RegistryConfig registryConfig = new RegistryConfig();
            registryConfig.setAddress("zookeeper://localhost:2181");
            return registryConfig;
        }
    }

另外一种情况就是zookeeper的版本问题了，可以在pom文件中移除内置的zookeeper，然后在手动添加合适版本的zookeeper依赖包了。
