dubbo + springcloud(eureka) 注册有效/外网IP

问题描述

在多网卡（虚拟网卡，云服务器内网/外网）的情况下，微服务注册的IP,不是有效IP，造成服务不可用

处理思路

解决方法：

• 服务器配置hosts
• 代码或者配置里规定IP

两种办法维护太麻烦

我的方式：

• 自动解析当前的有效IP并使用此IP注册

代码

提供获取有效/外网IP接口

复制代码// 接口 /** * IP * @return */ @GetMapping("/ip") public Object ip(HttpServletRequest request) { return RequestUtil.getIpAddress(request); } // 工具方法 /** * ip * @param request * @return */ public static String getIpAddress(HttpServletRequest request) { return getIpAddressList(request).get(0); } /** * ip * @param request * @return */ public static List<String> getIpAddressList(HttpServletRequest request) { List<String> list = Lists.newArrayList(); String xip = request.getHeader("x-forwarded-for"); if (!checkIP(xip)) { list.add(xip); } String pip = request.getHeader("Proxy-Client-IP"); if (!checkIP(pip)) { list.add(pip); } String wip = request.getHeader("WL-Proxy-Client-IP"); if (!checkIP(wip)) { list.add(wip); } String hip = request.getHeader("HTTP_CLIENT_IP"); if (!checkIP(hip)) { list.add(hip); } String hxip = request.getHeader("HTTP_X_FORWARDED_FOR"); if (!checkIP(hxip)) { list.add(hxip); } String ip = request.getRemoteAddr(); if (!checkIP(ip)) { list.add(ip); } return list; } public static boolean checkIP(String ip) { return ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip); }

// 接口

@GetMapping("/ip")
public Object ip(HttpServletRequest request) {
return RequestUtil.getIpAddress(request);
}
// 工具方法

return list;

eureka使用此IP注册

复制代码@Slf4j public class EurekaIpAddressUtil { public static void initConfig() { Properties properties = EurekaIpAddressUtil.getClasspathProperties("eureka.properties"); if(properties == null) { return; } String serviceUrl = properties.getProperty("eureka.serviceUrl"); log.info(serviceUrl); if(serviceUrl == null || "".equals(serviceUrl.trim())) { return; } String url = serviceUrl.replace("eureka/", "public/ip"); log.info(url); String ipAddress = UrlHttpUtil.get(url); log.info(ipAddress); if(ipAddress == null) { return; } // eureka System.setProperty("eureka.instance.ipAddress", ipAddress); // dubbo使用此设置，代码其他一样 //System.setProperty("dubbo.provider.host", ipAddress); } public static Properties getClasspathProperties(String path) { try { Properties properties = new Properties(); InputStream in = EurekaIpAddressUtil.class.getClassLoader().getResourceAsStream(path); properties.load(in); return properties; } catch (IOException e) { e.printStackTrace(); } return null; } }

String serviceUrl = properties.getProperty("eureka.serviceUrl");
log.info(serviceUrl);
if(serviceUrl == null || "".equals(serviceUrl.trim())) {

}
String url = serviceUrl.replace("eureka/", "public/ip");
log.info(url);
String ipAddress = UrlHttpUtil.get(url);
log.info(ipAddress);
if(ipAddress == null) {
return;
}
// eureka
System.setProperty("eureka.instance.ipAddress", ipAddress);
// dubbo使用此设置，代码其他一样
//System.setProperty("dubbo.provider.host", ipAddress);
}
public static Properties getClasspathProperties(String path) {
try {
Properties properties = new Properties();
InputStream in = EurekaIpAddressUtil.class.getClassLoader().getResourceAsStream(path);
properties.load(in);
return properties;
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}

其他注册也是类似处理
