前言
- 很多时候,项目里需要展示用户的IP属地信息,所以这篇文章就记录一下如何在Java Spring boot项目里获取请求的IP属地
步骤
在pom文件中引入下列依赖
<!-- 该依赖可以根据ip地址获取该ip相关的信息 --><dependency><groupId>net.dreamlu</groupId><artifactId>mica-ip2region</artifactId><version>2.5.6</version></dependency>
IpUtil工具类
- 该工具类对HttpServletRequest解析,得到ip地址字符串
public class IpUtil {/*** 获取客户端ip** @param request* @return*/public static String getIp(HttpServletRequest request) {String ip = request.getHeader("x-forwarded-for");if (ip != null && ip.length() != 0 && !"unknown".equalsIgnoreCase(ip)) {// 多次反向代理后会有多个ip值,第一个ip才是真实ipif (ip.indexOf(",") != -1) {ip = ip.split(",")[0];}}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.getHeader("X-Real-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getRemoteAddr();}return ip;}
}
在Controller层编写接口,获取请求的IP属地
@RestController
@RequestMapping("/part/util")
@Api(tags = "工具类", value = "UtilController")
public class UtilController {@Autowiredprivate Ip2regionSearcher ip2regionSearcher; // 核心处理类@ApiOperation(value = "获取ip属地")@GetMapping("/ipCity")public String getipCity(HttpServletRequest request) {String ip = IpUtil.getIp(request);IpInfo ipInfo = ip2regionSearcher.memorySearch(ip);String city = ipInfo.getCity();return city;}
}
测试接口
- 这里我的请求是内网ip,所以返回的结果是“内网ip”,有点像废话hhh。
IpInfo类中的方法
简单介绍一下几个常见的方法
ipInfo.getCountry(); // 国家中文名称
ipInfo.getProvince(); // 中国省份中文名称
ipInfo.getAddress(); // 详细地址
ipInfo.getIsp(); // 互联网服务提供商
ipInfo.isOverseas(); // 是否是国外
ipInfo.getLat(); // 纬度
ipInfo.getLng(); // 经度
