一、获取客户端ip的方法
//传入request对象，获得客户端ip
//注意，本地不行，本地会获取到0:0:0:0:0:0:0:1；服务器上是正常的
public static String getIpAddress(HttpServletRequest request) {
String ip = request.getHeader("x-forwarded-for");
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
//本地会获取到0:0:0:0:0:0:0:1
ip = request.getRemoteAddr();
}
if (ip.contains(",")) {
return ip.split(",")[0];
} else {
return ip;
}
}
二、获取服务器ip的方法
public static String getServerIP() {
String ip = null;
try {
//获取当前服务器ip
ip = InetAddress.getLocalHost().getHostAddress();
} catch (UnknownHostException e) {
LOG.error("获取当前服务器ip报错", e);
}
return ip;
}
三、其它备注
1.可以用RestTemplate发送http请求文章来源地址https://www.toymoban.com/news/detail-503234.html
import org.springframework.web.client.RestTemplate;
RestTemplate restTemplate = new RestTemplate();
//这个是发送get请求，然后把返回报文转为string类型
String htmlXml = restTemplate.getForObject("www.baidu.com", String.class);
