离线版IP归属地查询

这里简单介绍一下Ip2regionSearcher是什么？

ip2region 是准确率 99.9% 的 IP 地址定位库，0.0x毫秒级查询，提供了 Java、PHP、C、Python、Node.js、Golang、C#、Rust、Lua的查询绑定和 Binary、B树、内存三种查询算法！

Setp1：导入依赖

<dependency><groupId>net.dreamlu</groupId><artifactId>mica-ip2region</artifactId><version>2.5.6</version>
</dependency>
<dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.8.11</version>
</dependency>

提示：Ip2regionSearcher的和hutool工具包依赖包，这里导入hutool为了后期利用获取IP工具类

Setp2：编写测试接口

import cn.hutool.extra.servlet.ServletUtil;
import lombok.RequiredArgsConstructor;
import net.dreamlu.mica.ip2region.core.Ip2regionSearcher;
import net.dreamlu.mica.ip2region.core.IpInfo;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;/*** <p>* 测试控制器* <p>** @className: XController* @author: BertXie* @create: 2023-01-09 11:40*/@RestController
@RequiredArgsConstructor
public class XController {private final Ip2regionSearcher searchSearcher;@GetMapping("/ip")public String getHomeLocation(HttpServletRequest request) {IpInfo ipInfo = searchSearcher.memorySearch(ServletUtil.getClientIP(request));return ipInfo != null ? ipInfo.getCity() : "未知星球";}}

注意：这里注入了Ip2regionSearcher对象，并使用了memorySearch方法，会返回一个IP详情对象，还用到了Hutool工具的获取IP的方法ServletUtil.getClientIP
