java获取当前接口请求路径的几种方法
java获取当前接口请求路径的几种方法在Java开发中，有时候我们需要获取当前接口的请求路径，以便进行一些处理。
下面我将介绍几种常用的方法来获取当前接口的请求路径。
1. 使用HttpServletRequest对象在Servlet或者Spring MVC中，我们可以通过HttpServletRequest对象获取当前请求的路径。
可以使用如下代码来获取：```HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();String requestUrl = request.getRequestURL().toString();String queryString = request.getQueryString();String fullPath = requestUrl + (queryString != null ? "?" + queryString : "");```通过`getRequestURL()`方法获取请求的URL，再使用`getQueryString()`方法获取请求URL中的查询参数。
最后将二者拼接起来，即可得到完整的请求路径。
2. 使用HttpRequestUtils工具类如果项目中没有使用Servlet或Spring MVC框架，我们可以自己编写一个HttpRequestUtils工具类，代码如下：```import javax.servlet.http.HttpServletRequest;public class HttpRequestUtils {public static String getRequestUrl(HttpServletRequest request) {StringBuffer requestUrl = request.getRequestURL();String queryString = request.getQueryString();String fullPath = requestUrl + (queryString != null ? "?" + queryString : "");return fullPath;}}```在需要获取请求路径的地方，如下调用该工具类的方法即可：```HttpServletRequest request = ...;String requestUrl = HttpRequestUtils.getRequestUrl(request);```3. 使用JAX-RS的UriInfo对象如果你在使用JAX-RS开发RESTful服务，可以使用UriInfo对象获取请求路径。

java获取linux服务器上的IP操作
java获取linux服务器上的IP操作在编码过程中需要获取本地IP地址，⾸先使⽤的是下⾯的⽅法，在Windows环境正常，但是linux服务器上就获取不到，public static String getIpAddress() {String hostAddress = "";try {InetAddress address = InetAddress.getLocalHost();hostAddress = address.getHostAddress();} catch (UnknownHostException e) {e.printStackTrace();}return hostAddress;}这样在linux上依然获取到的是127.0.0.1，查询服务器上⾯IP发现：[mm_cbms1@localhost ~]$ ip address1:lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWNlink/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host loinet6 ::1/128 scope hostvalid_lft forever preferred_lft forever2:eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000link/ether 00:50:56:a2:0d:1b brd ff:ff:ff:ff:ff:ffinet 10.12.8.243/24 brd 10.12.8.255 scope global eth0inet6 fe80::250:56ff:fea2:d1b/64 scope linkvalid_lft forever preferred_lft forever这⾥⾸先要了解上⾯列出的接⼝中的含义：1、linux的⽹络接⼝之扫盲(1) ⽹络接⼝的命名这⾥并不存在⼀定的命名规范，但⽹络接⼝名字的定义⼀般都是要有意义的。
JAVA如何获取客户端IP地址和MAC地址
JAVA如何获取客户端IP地址和MAC地址本⽂介绍了JAVA如何获取客户端IP地址和MAC地址，分享给⼤家，具体如下：1.获取客户端IP地址public String getIp(HttpServletRequest request) throws Exception {String ip = request.getHeader("X-Forwarded-For");if (ip != null) {if (!ip.isEmpty() && !"unKnown".equalsIgnoreCase(ip)) {int index = ip.indexOf(",");if (index != -1) {return ip.substring(0, index);} else {return ip;}}}ip = request.getHeader("X-Real-IP");if (ip != null) {if (!ip.isEmpty() && !"unKnown".equalsIgnoreCase(ip)) {return ip;}}return request.getRemoteAddr();}为什么不直接使⽤request.getRemoteAddr()；⽽要在之前判断两个请求头"X-Forwarded-For"和"X-Real-IP"X-Forwarded-For: client1, proxy1, proxy2, proxy3其中的值通过⼀个逗号+空格把多个IP地址区分开, 最左边(client1)是最原始客户端的IP地址, 代理服务器每成功收到⼀个请求，就把请求来源IP地址添加到右边。
所有我们只取第⼀个IP地址X-Real-IP，⼀般只记录真实发出请求的客户端IP解决⽤localhost访问ip为0:0:0:0:0:0:0:1的问题public String getIp(HttpServletRequest request) throws Exception {String ip = request.getHeader("X-Forwarded-For");if (ip != null) {if (!ip.isEmpty() && !"unKnown".equalsIgnoreCase(ip)) {int index = ip.indexOf(",");if (index != -1) {return ip.substring(0, index);} else {return ip;}}}ip = request.getHeader("X-Real-IP");if (ip != null) {if (!ip.isEmpty() && !"unKnown".equalsIgnoreCase(ip)) {return ip;}}ip = request.getHeader("Proxy-Client-IP");if (ip != null) {if (!ip.isEmpty() && !"unKnown".equalsIgnoreCase(ip)) {return ip;}}ip = request.getHeader("WL-Proxy-Client-IP");if (ip != null) {if (!ip.isEmpty() && !"unKnown".equalsIgnoreCase(ip)) {return ip;}}ip = request.getRemoteAddr();return ip.equals("0:0:0:0:0:0:0:1") ? "127.0.0.1" : ip;}2.获取客户端MAC地址UdpGetClientMacAddr umac = new UdpGetClientMacAddr(sip);String smac = umac.GetRemoteMacAddr();添加⼀个获取MAC的时间限制final UdpGetClientMacAddr umac = new UdpGetClientMacAddr(sip);//---长时间获取不到MAC地址则放弃ExecutorService exec = Executors.newFixedThreadPool(1);Callable<String> call = new Callable<String>() {public String call() throws Exception {return umac.GetRemoteMacAddr();}};try {Future<String> future = exec.submit(call);String smac = future.get(1000 * 1, LISECONDS);loginMonitor.setMacAddress(smac);} catch (TimeoutException ex) {loginMonitor.setMacAddress("获取失败");("获取MAC地址超时");}// 关闭线程池exec.shutdown();//---需要先获取IP地址作为参数构造⼀个UdpGetClientMacAddrUdpGetClientMacAddr.javapackage monsys.security.controller;import java.io.IOException;import .DatagramPacket;import .DatagramSocket;import .InetAddress;/*** 主机A向主机B发送“UDP－NetBIOS－NS”询问包，即向主机B的137端⼝，发Query包来询问主机B的NetBIOS Names信息。

分享给⼤家供⼤家参考，具体如下：前⼏天写过⼀个获取远程服务器的IP和端⼝的程序，从⽹上查了⼀些资料顺便加⼀些⾃⼰的理解，希望对⼤家有所帮助：struts2 获取requestHttpServletRequest requet=ServletActionContext.getRequest();requet.getScheme()+"://"+requet.getServerName()+":"+requet.getServerPort()request.getHeader("User-Agent"); //就是取得客户端的系统版本request.getRemoteAddr(); //取得客户端的IPrequest.getRemoteHost() //取得客户端的主机名request.getRemotePort(); //取得客户端的端⼝request.getRemoteUser(); //取得客户端的⽤户request.getLocalAddr(); //取得服务器IPrequest.getLocalPort(); //取得服务器端⼝1、JSP中获得当前应⽤的相对路径和绝对路径根⽬录所对应的绝对路径:request.getRequestURI()⽂件的绝对路径 :application.getRealPath(request.getRequestURI());当前web应⽤的绝对路径 :application.getRealPath("/");取得请求⽂件的上层⽬录:new File(application.getRealPath(request.getRequestURI())).getParent()2 Servlet中获得当前应⽤的相对路径和绝对路径根⽬录所对应的绝对路径:request.getServletPath();⽂件的绝对路径 :request.getSession().getServletContext().getRealPath(request.getRequestURI())当前web应⽤的绝对路径 :servletConfig.getServletContext().getRealPath("/");ServletContext对象获得⼏种⽅式：javax.servlet.http.HttpSession.getServletContext()javax.servlet.jsp.PageContext.getServletContext()javax.servlet.ServletConfig.getServletContext()3.Java类中获得绝对路径根据java.io.File的Doc⽂挡，可知: 默认情况下new File("/")代表的⽬录为：System.getProperty("user.dir")。
java中连接服务器用法
java中连接服务器用法在Java中，连接服务器通常使用Socket类。
Socket类提供了一种客户端和服务器之间进行通信的机制。
首先，客户端需要创建一个Socket对象来连接服务器。
可以通过指定服务器的IP地址和端口号来创建Socket对象。
例如，以下代码创建一个Socket对象并连接到本地主机的80端口：```javaString serverIP = "127.0.0.1";int serverPort = 80;Socket socket = new Socket(serverIP, serverPort);```在连接服务器之后，客户端可以使用Socket对象的输入输出流进行数据的发送和接收。
可以通过getInputStream()方法获取输入流，通过getOutputStream()方法获取输出流。
例如，以下代码从服务器接收数据并发送数据给服务器：```java// 从服务器接收数据InputStream inputStream = socket.getInputStream();BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));String response = reader.readLine();System.out.println("服务器响应：" + response);// 发送数据给服务器OutputStream outputStream = socket.getOutputStream();PrintWriter writer = new PrintWriter(outputStream, true);writer.println("Hello Server");```在与服务器通信完成后，客户端可以关闭Socket连接。
