dubbo. registry.address:配置spring-cloud://localhost或者不配置启动会报错，但最终能注册成功
版本
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-dependencies</artifactId>
<version>2.2.0.RELEASE</version>
会出现两次异常，通过debug发现是默认注册localhost:9090时候出错，但是最终注册成功，不影响服务的调用
第一次异常日志

如果配置 dubbo. registry.address: spring-cloud://localhost:8848 正常启动无报错信息
spring-cloud://localhost是没有必要的。
如果不加启动dubbo 项目时会向 注册中心localhost:9090进行注册，但是实际上我并没有配置localhost:9090,这是源码中默认的，所以会有两次注册失败后才会注册到springcloud配置的注册中心

您解决了吗？谢谢！
发现是findConfigedHosts方法的一个逻辑问题，特别是springcloud集成dubbo之后，springcloudalibaba默认的 dubbo.registry.address为spring-cloud://localhost,实际的配置地址是spring.cloud.discovery.server-addr,
if (isInvalidLocalHost(hostToBind)) {
if (CollectionUtils.isNotEmpty(registryURLs)) {
for (URL registryURL : registryURLs) {
if (MULTICAST.equalsIgnoreCase(registryURL.getParameter("registry"))) {
// skip multicast registry since we cannot connect to it via Socket
continue;
}
try (Socket socket = new Socket()) {
SocketAddress addr = new InetSocketAddress(registryURL.getHost(), registryURL.getPort());
// 核心代码如下，这里注册中心的地址是spring-cloud://localhost的localhost，一个兼容地址
// 后面的逻辑就是连接注册中心，成功之后获取本地地址就ok了，但这是个兼容地址，没有实际意义，
// 算是个占位
socket.connect(addr, 1000);
hostToBind = socket.getLocalAddress().getHostAddress();
break;
} catch (Exception e) {
logger.warn(e.getMessage(), e);
}
}
}
// 但最终还是能够成功获取到合法的ip地址，是否上面的logger.warn ignore处理一下，还是有更好的优化方案呢。
if (isInvalidLocalHost(hostToBind)) {
hostToBind = getLocalHost();
}
}
简单的可以设置DUBBO_IP_TO_BIND环境变量指定ip处理，但是对用户来说不够透明。 @mercyblitz
好像2.7.16这段代码的逻辑已经改了，不会再报warn错了，可以试试
private String findConfigedHosts(ProtocolConfig protocolConfig,
List<URL> registryURLs,
Map<String, String> map) {
boolean anyhost = false;
String hostToBind = getValueFromConfig(protocolConfig, DUBBO_IP_TO_BIND);
if (hostToBind != null && hostToBind.length() > 0 && isInvalidLocalHost(hostToBind)) {
throw new IllegalArgumentException("Specified invalid bind ip from property:" + DUBBO_IP_TO_BIND + ", value:" + hostToBind);
}
// if bind ip is not found in environment, keep looking up
if (StringUtils.isEmpty(hostToBind)) {
hostToBind = protocolConfig.getHost();
if (provider != null && StringUtils.isEmpty(hostToBind)) {
hostToBind = provider.getHost();
}
if (isInvalidLocalHost(hostToBind)) {
anyhost = true;
logger.info("No valid ip found from environment, try to get local host.");
hostToBind = getLocalHost();
}
}
map.put(BIND_IP_KEY, hostToBind);
// registry ip is not used for bind ip by default
String hostToRegistry = getValueFromConfig(protocolConfig, DUBBO_IP_TO_REGISTRY);
if (hostToRegistry != null && hostToRegistry.length() > 0 && isInvalidLocalHost(hostToRegistry)) {
throw new IllegalArgumentException(
"Specified invalid registry ip from property:" + DUBBO_IP_TO_REGISTRY + ", value:" + hostToRegistry);
} else if (StringUtils.isEmpty(hostToRegistry)) {
// bind ip is used as registry ip by default
hostToRegistry = hostToBind;
}
map.put(ANYHOST_KEY, String.valueOf(anyhost));
return hostToRegistry;
}
