Spring 自带 MD5加密:
String password="123";
DigestUtils.md5DigestAsHex(password.getBytes())
import javax.servlet.http.HttpServletRequest;
import java.net.InetAddress;
import java.net.UnknownHostException;
public class IpUtil {
private static final String UNKNOWN = "unknown";
private static final String LOCALHOST_IP = "127.0.0.1";
private static final String LOCALHOST_IPV6 = "0:0:0:0:0:0:0:1";
private static final String SEPARATOR = ",";
public static String getIpAddress(HttpServletRequest request) {
if (request == null) {
return "unknown";
}
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("X-Forwarded-For");
}
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("X-Real-IP");
}
if (ip == null || ip.length() == 0 || UNKNOWN.equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
if (LOCALHOST_IP.equalsIgnoreCase(ip) || LOCALHOST_IPV6.equalsIgnoreCase(ip)) {
InetAddress iNet = null;
try {
iNet = InetAddress.getLocalHost();
} catch (UnknownHostException e) {
e.printStackTrace();
}
if (iNet != null)
ip = iNet.getHostAddress();
}
}
if (ip != null && ip.length() > 15) {
if (ip.indexOf(SEPARATOR) > 0) {
ip = ip.substring(0, ip.indexOf(SEPARATOR));
}
}
return LOCALHOST_IPV6.equals(ip) ? LOCALHOST_IP : ip;
}
}
然后直接调用
- String ip=IpUtil.getIpAddress(request);
