一、获取IP工具类
public class IpUtil {
public static String getIpAddr(HttpServletrequest request) {
String ipAddress = null;
try {
ipAddress = request.getHeader("x-forwarded-for");
if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
ipAddress = request.getHeader("Proxy-Client-IP");
}
if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
ipAddress = request.getHeader("WL-Proxy-Client-IP");
}
if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
ipAddress = request.getRemoteAddr();
if (ipAddress.equals("127.0.0.1")) {
// 根据网卡取本机配置的IP
InetAddress inet = null;
try {
inet = InetAddress.getLocalHost();
} catch (UnknownHostException e) {
e.printStackTrace();
}
ipAddress = inet.getHostAddress();
}
}
// 对于通过多个代理的情况，第一个IP为客户端真实IP,多个IP按照','分割
if (ipAddress != null && ipAddress.length() > 15) { // "***.***.***.***".length()
// = 15
if (ipAddress.indexOf(",") > 0) {
ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));
}
}
} catch (Exception e) {
ipAddress = "";
}
// ipAddress = this.getRequest().getRemoteAddr();
System.out.println("用户ip：" ipAddress);
return ipAddress;
}
}
二、控制器
@Controller
public class IndexController {
@GetMapping("/test")
public String getInfo(Model model){
model.addAttribute("ipadd",getip());
model.addAttribute("curdate",getdate());
return "test";
}
// 获取IP地址
private String getip() {
HttpServletRequest request = ((ServletRequestAttributes) (RequestContextHolder.currentRequestAttributes()))
.getRequest();
return IpUtil.getIpAddr(request);
}
//获取当前时间
private String getdate() {
Date date = new Date();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(df.format(date));
return df.format(date);
}
}
三、前端页面
<body>
您的IP是<span th:text="${ipadd}"></span><br>
服务器当前时间：<span th:text="${curdate}"></span>
</body>
