springboot 获取客户端ip

使用Spring Boot获取客户端IP，可以通过HttpServletRequest对象来获取。可以使用“@Autowired”注解自动注入HttpServletRequest对象，然后使用“getRemoteAddr()”方法获取客户端IP地址。

springboot 获取ip

在 Spring Boot 中，可以通过 HttpServletRequest 对象获取客户端的 IP 地址。具体实现如下：

@GetMapping("/getIp")
public String getIp(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)) {
        ip = request.getHeader("HTTP_CLIENT_IP");
    }
    if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
        ip = request.getHeader("HTTP_X_FORWARDED_FOR");
    }
    if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
        ip = request.getRemoteAddr();
    }
    return ip;
}

springboot获取ip

在Spring Boot中，可以通过HttpServletRequest对象来获取客户端的IP地址。可以使用以下代码获取IP地址：

@RestController
public class MyController {

    @Autowired
    private HttpServletRequest request;

    @GetMapping("/ip")
    public String getClientIp() {
        String 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") || ipAddress.equals("0:0:0:0:0:0:0:1")) {
                // 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();
            }
        }
        return ipAddress;
    }
}

在上述代码中，我们首先尝试从请求头中获取IP地址，如果获取不到再从其他方式获取。其中，`X-Forwarded-For`、`Proxy-Client-IP`、`WL-Proxy-Client-IP`是常见的代理服务器转发的请求头，可以通过它们获取到真实的客户端IP地址。如果无法从请求头中获取到IP地址，则通过`request.getRemoteAddr()`方法获取IP地址。对于本机访问的情况，IP地址为"127.0.0.1"或"0:0:0:0:0:0:0:1"，这时候我们可以通过`InetAddress.getLocalHost()`方法获取本机的IP地址。

以上代码将获取到的IP地址作为响应返回，你可以将这个代码片段集成到你的Spring Boot应用程序中，然后访问`/ip`路径来获取客户端的IP地址。
