Java获取 IP 详细信息、经纬度
可以自己搭建，也可以直接使用现成的请求链接，每个月月初更新 ip 库
获取城市信息：http://ip.guoxinqi.cn/city/47.96.229.169
获取IP经纬度信息：http://ip.guoxinqi.cn/position/47.96.229.169
自己搭建：
可用于拦截操作、获取 IP 详细信息、及黑名单操作获取。
拦截操作: MvcConfigurer中addInterceptors中指定拦截方法（/** 全部请求拦截），在 FilterHandler 的 preHandle 方法可做拦截后的操作（例：黑名单拦截、请求拦截）
IP 详细信息获取： 使用 InterceptServer 方法获取 ip 的详细信息，可获取国家、省份、城市、经纬度 等。（结合拦截操作可实现黑名单拦截、白名单放行、拦截指定国家、省份、城市的拦截操作）

软件架构
使用 SpringBoot ，GeoLite2City
新建项目（IP-Intercept）：

2、新建Applocation启动文件
package com.gitee.Intercept;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class InterceptApplication {
public static void main(String[] args) {
SpringApplication.run(InterceptApplication.class, args);
}
}
3、新建 FilterHandler 继承 HandlerInterceptor
package com.gitee.Intercept.filter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
public class FilterHandler implements HandlerInterceptor{
/*
* 在调用controller方法之前会调用此方法，返回true会正常执行程序，返回false折中断执行，
* 可以做拦截操作，比如黑名单之类的
*
*/
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
// TODO Auto-generated method stub
return true;
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
// TODO Auto-generated method stub
}
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
throws Exception {
// TODO Auto-generated method stub
}
}
4、新建 视图管理器 MvcConfigurer 继承 WebMvcConfigurer
package com.gitee.Intercept.filter;
import java.util.List;
import org.springframework.context.annotation.Configuration;
import org.springframework.format.FormatterRegistry;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.validation.MessageCodesResolver;
import org.springframework.validation.Validator;
import org.springframework.web.method.support.HandlerMethodArgumentResolver;
import org.springframework.web.method.support.HandlerMethodReturnValueHandler;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.config.annotation.AsyncSupportConfigurer;
import org.springframework.web.servlet.config.annotation.ContentNegotiationConfigurer;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.PathMatchConfigurer;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class MvcConfigurer implements WebMvcConfigurer{
/**
* 拦截方法（/** 拦截所有）
*/
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new FilterHandler()).addPathPatterns("/**");
}
}
5、封装 获取 ip详细信息 InterceptServer
package com.gitee.Intercept.server;
import java.io.File;
import java.io.IOException;
import java.net.InetAddress;
import java.net.UnknownHostException;
import javax.annotation.PostConstruct;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;
import com.maxmind.geoip2.DatabaseReader;
import com.maxmind.geoip2.exception.GeoIp2Exception;
import com.maxmind.geoip2.model.CityResponse;
@Service
public class InterceptServer {
private static Logger logger = LoggerFactory.getLogger(InterceptServer.class);
private static CityResponse city ;
//@Value("${file.GeoLite2City}")
private static final String filePath = "/geoLite2City/GeoLite2-City.mmdb";
private static DatabaseReader reader;
@PostConstruct
public void init() {
try {
File file = new ClassPathResource(filePath).getFile();
reader = new DatabaseReader.Builder(file).build();
} catch (Exception e) {
logger.error("IP init failed :"+e.getMessage() , e);
}
}
public CityResponse getCity(String ipAddress) {
getResponse(ipAddress);
return city;
}
private CityResponse getResponse(String ipAddress) {
if(StringUtils.isEmpty(ipAddress)) {
throw new NullPointerException();
}
try {
InetAddress address = InetAddress.getByName(ipAddress);
this.city = reader.city(address);
} catch (UnknownHostException e) {
logger.error("DNS oarsing failed : " +e.getMessage(),e);
} catch (IOException e) {
logger.error("not exist file : "+e.getMessage(),e);
} catch (GeoIp2Exception e) {
logger.error("GeoIp2 faild : "+e.getMessage(),e);
}
return null;
}
}
5、新建application.yml 文件，空的
6、下载GeoLite2-City，地址 https://dev.maxmind.com/geoip/geoip2/geolite2/
7、新建IndexController
package com.gitee.Intercept.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.ResponseBody;
import com.gitee.Intercept.server.InterceptServer;
import com.maxmind.geoip2.model.CityResponse;
@Controller
public class IndexController {
@Autowired
private InterceptServer interceptServer;
@GetMapping("/a//{ip}")
@ResponseBody
public String test(@PathVariable("ip") String ip) {
CityResponse country = interceptServer.getCity(ip);
return String.valueOf(country);
}
}
8、启动，访问路径http://localhost:8080/a/ip地址
如图所示
