AddressUtils 、RegionUtils IP地址工具类

一、类展示

AddressUtils ：

/*** 获取地址类**/
@Slf4j
@NoArgsConstructor(access = AccessLevel.PRIVATE)
public class AddressUtils {// 未知地址public static final String UNKNOWN = "XX XX";public static String getRealAddressByIP(String ip) {if (StringUtils.isBlank(ip)) {return UNKNOWN;}// 内网不查询ip = StringUtils.contains(ip, "0:0:0:0:0:0:0:1") ? "127.0.0.1" : HtmlUtil.cleanHtmlTag(ip);if (NetUtil.isInnerIP(ip)) {return "内网IP";}return RegionUtils.getCityInfo(ip);}
}

RegionUtils  ：

ip资源库：ip2region.xdb  已经上传资源：

*** 根据ip地址定位工具类，离线方式* 参考地址：<a href="https://gitee.com/lionsoul/ip2region/tree/master/binding/java">集成 ip2region 实现离线IP地址定位库</a>**/
@Slf4j
public class RegionUtils {private static final Searcher SEARCHER;// 初始化IP库：ip2region.xdbstatic {// 从classpath加载ip2region.xdbString fileName = "/ip2region.xdb";File existFile = FileUtils.file(FileUtil.getTmpDir() + FileUtil.FILE_SEPARATOR + fileName);// 如果文件不存在，则从classpath加载if (!FileUtils.exist(existFile)) {ClassPathResource fileStream = new ClassPathResource(fileName);if (ObjectUtil.isEmpty(fileStream.getStream())) {throw new ServiceException("RegionUtils初始化失败，原因：IP地址库数据不存在！");}FileUtils.writeFromStream(fileStream.getStream(), existFile);}String dbPath = existFile.getPath();// 1、从 dbPath 加载整个 xdb 到内存。byte[] cBuff;try {cBuff = Searcher.loadContentFromFile(dbPath);} catch (Exception e) {throw new ServiceException("RegionUtils初始化失败，原因：从ip2region.xdb文件加载内容失败！" + e.getMessage());}// 2、使用上述的 cBuff 创建一个完全基于内存的查询对象。try {SEARCHER = Searcher.newWithBuffer(cBuff);} catch (Exception e) {throw new ServiceException("RegionUtils初始化失败，原因：" + e.getMessage());}}/*** 根据IP地址离线获取城市*/public static String getCityInfo(String ip) {try {ip = ip.trim();// 3、执行查询String region = SEARCHER.search(ip);// 返回查询结果return region.replace("0|", "").replace("|0", "");} catch (Exception e) {log.error("IP地址离线获取城市异常 {}", ip);return "未知";}}
}

二、测试IP地址判断

@RestController
@SaIgnore
public class TestIPUtils {@GetMapping("getIp")public String getCityInfo() {Console.log("空", AddressUtils.getRealAddressByIP(""));Console.log("127.0.0.1",AddressUtils.getRealAddressByIP("127.0.0.1"));Console.log("183.82.118.0",AddressUtils.getRealAddressByIP("183.82.118.0"));return "ok";}}

打印结果：

空 XX XX
127.0.0.1 内网IP
183.82.118.0 印度|安德拉|海得拉巴|ACT
