获取IP

public static String getIp(HttpServletRequest request){
        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("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.getRemoteAddr();
        }
        return ip;
    }

根据IP解析地址

在网上一番寻找，希望能找到一个根据IP解析地址的API，终于不负有心人，让我找到了，可是这个API是一个webservice，于是又学会了webservice调用，这个API来自webxml.com.cn，有着丰富的webservice接口，通过soapui调用情况如下图
http://ws.webxml.com.cn/WebServices/IpAddressSearchWebService.asmx?wsdl

Java获取请求者IP和地址

下面是实现根据IP获取地址的静态工具方法，说明：
userIp：不用多说，是上面方法获取到的IP
soapConnector: 简单说，就是soap接口的请求入口
再看方法里边，我们定义了url（实际请求地址）、request（顾名思义，定义请求报文的）、response（顾名思义，是咱们需要的响应啦）soapAction（可自行了解Soap接口为啥需要soapaction，如果不传，我们是无法调用成功的），下面我们一个个来。

public static String getAddressByIp(String userIp, SOAPConnector soapConnector){
        String address = "";
        String url = "http://ws.webxml.com.cn/WebServices/IpAddressSearchWebService.asmx";
        GetCountryCityByIp request = new GetCountryCityByIp();
        request.setTheIpAddress(userIp);
        SoapActionCallback soapAction = new SoapActionCallback("http://WebXml.com.cn/getCountryCityByIp");
        GetCountryCityByIpResponse response = (GetCountryCityByIpResponse) soapConnector.callWebService(url, request, soapAction);
        address = response.getGetCountryCityByIpResult().getString().get(1);
        return address;
    }

GetCountryCityByIp 和 GetCountryCityByIpResponse
实际上，这两个类是通过maven的插件生成的
需要修改的节点为generatePackage，更换成自己的包路径
然后执行maven的compile，会在对应的包路径下生成一些类，这些类对应着webservice每个方法里的请求和响应

Java获取请求者IP和地址

soapAction，可以通过soapui获取

Java获取请求者IP和地址

soapConnector
除了SoapConnector，还需要一个配置类

package cn.xyp.utils.soap.consumer.client;

import org.springframework.ws.client.core.support.WebServiceGatewaySupport;
import org.springframework.ws.soap.client.core.SoapActionCallback;

public class SOAPConnector extends WebServiceGatewaySupport {

    public Object callWebService(String url, Object request, SoapActionCallback soapAction) {
        return getWebServiceTemplate().marshalSendAndReceive(url, request, soapAction);
    }
}

package cn.xyp.utils.soap.consumer.config;

import cn.xyp.utils.soap.consumer.client.SOAPConnector;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;

@Configuration
public class SoapClientConfig {

    @Bean
    public Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        marshaller.setContextPath("cn.xyp.utils.soap.consumer.generated");
        return marshaller;
    }

    @Bean
    public SOAPConnector soapConnector(Jaxb2Marshaller marshaller) {
        SOAPConnector client = new SOAPConnector();
        client.setDefaultUri("http://ws.webxml.com.cn/WebServices/IpAddressSearchWebService.asmx");
        client.setMarshaller(marshaller);
        client.setUnmarshaller(marshaller);
        return client;
    }
}

如何调用getAddressByIp

@Autowired
private SOAPConnector soapConnector;

IpUtil.getAddressByIp(userIp, soapConnector)

测试

@Test
public void getAddressByIp(){
    String url = "http://ws.webxml.com.cn/WebServices/IpAddressSearchWebService.asmx";
    GetCountryCityByIp request = new GetCountryCityByIp();
    request.setTheIpAddress("101.227.1.197");
    SoapActionCallback soapAction = new SoapActionCallback("http://WebXml.com.cn/getCountryCityByIp");
    GetCountryCityByIpResponse response = (GetCountryCityByIpResponse) soapConnector.callWebService(url, request, soapAction);
    System.out.println(response.getGetCountryCityByIpResult().getString().get(1));
}
