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 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 {      /**      * 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 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;     } }
