java获取真实ip及真实地址工具类

废话就不多说了,直接上码吧!

IpUtils.java类

package com.fish.common.utils; import java.net.InetAddress; import java.net.UnknownHostException; import javax.servlet.http.HttpServletRequest; public class IpUtils { public static String getIpAddr(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(); } return “0:0:0:0:0:0:0:1”.equals(ip) ? “127.0.0.1” : ip; } public static boolean internalIp(String ip) { byte[] addr = textToNumericFormatV4(ip); return internalIp(addr) || “127.0.0.1”.equals(ip); } private static boolean internalIp(byte[] addr) { if (StringUtils.isNull(addr) || addr.length < 2) { return true; } final byte b0 = addr[0]; final byte b1 = addr[1]; final byte SECTION_1 = 0x0A; final byte SECTION_2 = (byte) 0xAC; final byte SECTION_3 = (byte) 0x10; final byte SECTION_4 = (byte) 0x1F; final byte SECTION_5 = (byte) 0xC0; final byte SECTION_6 = (byte) 0xA8; switch (b0) { case SECTION_1: return true; case SECTION_2: if (b1 >= SECTION_3 && b1 <= SECTION_4) { return true; } case SECTION_5: switch (b1) { case SECTION_6: return true; } default: return false; } } public static byte[] textToNumericFormatV4(String text) { if (text.length() == 0) { return null; } byte[] bytes = new byte[4]; String[] elements = text.split(“\\.“, -1); try { long l; int i; switch (elements.length) { case 1: l = Long.parseLong(elements[0]); if ((l < 0L) || (l > 4294967295L)) { return null; } bytes[0] = (byte) (int) (l >> 24 & 0xFF); bytes[1] = (byte) (int) ((l & 0xFFFFFF) >> 16 & 0xFF); bytes[2] = (byte) (int) ((l & 0xFFFF) >> 8 & 0xFF); bytes[3] = (byte) (int) (l & 0xFF); break; case 2: l = Integer.parseInt(elements[0]); if ((l < 0L) || (l > 255L)) { return null; } bytes[0] = (byte) (int) (l & 0xFF); l = Integer.parseInt(elements[1]); if ((l < 0L) || (l > 16777215L)) { return null; } bytes[1] = (byte) (int) (l >> 16 & 0xFF); bytes[2] = (byte) (int) ((l & 0xFFFF) >> 8 & 0xFF); bytes[3] = (byte) (int) (l & 0xFF); break; case 3: for (i = 0; i < 2; ++i) { l = Integer.parseInt(elements[i]); if ((l < 0L) || (l > 255L)) { return null; } bytes[i] = (byte) (int) (l & 0xFF); } l = Integer.parseInt(elements[2]); if ((l < 0L) || (l > 65535L)) { return null; } bytes[2] = (byte) (int) (l >> 8 & 0xFF); bytes[3] = (byte) (int) (l & 0xFF); break; case 4: for (i = 0; i < 4; ++i) { l = Integer.parseInt(elements[i]); if ((l < 0L) || (l > 255L)) { return null; } bytes[i] = (byte) (int) (l & 0xFF); } break; default: return null; } } catch (NumberFormatException e) { return null; } return bytes; } public static String getHostIp() { try { return InetAddress.getLocalHost().getHostAddress(); } catch (UnknownHostException e) { } return “127.0.0.1”; } public static String getHostName() { try { return InetAddress.getLocalHost().getHostName(); } catch (UnknownHostException e) { } return “未知”; } }

获取地址类:AddressUtils.java

package com.fish.common.utils; import com.fish.common.constant.Constants; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import com.alibaba.fastjson.JSONObject; import com.fish.common.utils.http.HttpUtils; public class AddressUtils { private static final Logger log = LoggerFactory.getLogger(AddressUtils.class); public static final String IP_URL = “http://whois.pconline.com.cn/ipJson.jsp”; public static final String UNKNOWN = “XX XX”; public static String getRealAddressByIP(String ip) { String address = UNKNOWN; if (IpUtils.internalIp(ip)) { return “内网IP”; } try { String rspStr = HttpUtils.sendGet(IP_URL, “ip=” + ip + “&json=true”, Constants.GBK); if (StringUtils.isEmpty(rspStr)) { log.error(“获取地理位置异常 {}”, ip); return UNKNOWN; } JSONObject obj = JSONObject.parseObject(rspStr); String region = obj.getString(“pro”); String city = obj.getString(“city”); return String.format(“%s %s”, region, city); } catch (Exception e) { log.error(“获取地理位置异常 {}”, e); } return address; } }
