2022-04-03 16:00:12.139 ERROR 21600 --- [p-nio-80-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://payment-service/payment/zk": connect timed out; nested exception is java.net.SocketTimeoutException: connect timed out] with root cause

java.net.SocketTimeoutException: connect timed out

解决方案如下：

1. 查看 linux 服务器上防火墙是否关闭，或者开放该 2181 端口
2. 如在虚拟机安装的zookeeper，查看本机是否能ping通 linux 服务器IP和端口，cmd命令：telnet 192.168.15.130 2181
3. 如win10本机有防火墙，检查是否关闭防火墙，或者防火墙开放端口
4. 如使用 RestTemplate 作为客户端访问zookeeper服务，确认是否已在RestTemplate配置类上添加注解：@LoadBalanced
