Java中使用HttpServletRequest获取ip和端口-详解
目录
1.简单例子
也可以直接用
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String ServerName = request.getServerName();//返回服务器的主机名
String ServerPort = request.getServerPort();//返回服务器的端口号
String uri = request.getRequestURI();//返回请求行中的资源名称
String url = request.getRequestURL().toString();//获得客户端发送请求的完整url
String ip = request.getRemoteAddr();//返回发出请求的IP地址
String params = request.getQueryString();//返回请求行中的参数部分
String host=request.getRemoteHost();//返回发出请求的客户机的主机名
int port =request.getRemotePort();//返回发出请求的客户机的端口号
System.out.println(ServerName);
System.out.println(ServerPort);
System.out.println(ip);
System.out.println(url);
System.out.println(uri);
System.out.println(params);
System.out.println(host);
System.out.println(port);
}2.详细使用例子---Java项目
真正用到在serviceImpl实现类中
2.1.Controller层
@RestController
@RequestMapping("/api")
public class DataReportController {
private final DataReportService dataReportService;
private final BusinessMsgCodeProperties props;
@Autowired
public DataReportController(DataReportService dataReportService, BusinessMsgCodeProperties props){
this.dataReportService = dataReportService;
this.props = props;
}
/**
* 数据上报接⼝
*/
@PostMapping("/dataReport")//这个接口既传文件参数又传实体实参,request不是参数,前端不传后端可自行获取
public Resource<String> dataReport(@RequestPart(value = "file", required = true) MultipartFile file, @RequestPart @Validated DataReportInDto dto, HttpServletRequest request){
String code = dataReportService.dataReport(file,dto,request);
return new Resource<>(props.getProcessStatus(code)); //Resource为自行封装的返回类型,可以用不用
}
}2.2service层
2.2.1接口
public interface DataReportService extends IService<ReportData> {
/**
* 数据上报接⼝
*/
String dataReport(MultipartFile file, DataReportInDto dto, HttpServletRequest request);
}2.2.2serviceImpl实现类
@Service
@Slf4j
public class DataReportServiceImpl extends ServiceImpl<DataReportMapper, ReportData> implements DataReportService {
private final DataReportMapper dataReportMapper;
@Autowired
public DataReportServiceImpl(DataReportMapper dataReportMapper){
this.dataReportMapper = dataReportMapper;
}
@Override
public String dataReport(MultipartFile file, DataReportInDto dto, HttpServletRequest request) {
//一、获取调用者的ip+port
String ip = "";
String port = "";
String loginName = "";
try {
ip = IpUtils.getRemoteHost(request); //自己封装一个工具类(对特殊情况做了一定处理)
String ip1 = request.getRemoteAddr(); //直接获取
port = String.valueOf(request.getRemotePort());
System.out.println("远程端的ip1:"+ip1);
System.out.println("远程的端口:"+ip);
System.out.println("远程端口:"+port);
log.info("获取调用者ip:"+ip+" ,"+"port:"+port);
} catch (Exception e) {
e.printStackTrace();
log.info("获取调用者ip+port失败");
}
return "COMMON_ERROR";
}
}3.IpUtils工具类
直接整个粘贴就能用
package com.nengyy.speed_rest_server.utils; //所在包
import org.apache.commons.lang3.StringUtils;
import javax.servlet.http.HttpServletRequest;
public class IpUtils {
public static String getRemoteHost(HttpServletRequest request){
String ip = request.getHeader("x-forwarded-for");
if(StringUtils.isNoneBlank(ip) && !"unknown".equalsIgnoreCase(ip)){
int idx = ip.indexOf(",");
if(idx != -1){
ip = ip.substring(0, idx);
}
}
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.getRemoteAddr();
}
return ip.equals("0:0:0:0:0:0:0:1")?"127.0.0.1":ip;
}
