1.前言
相信大家都看到别人写的项目里面都有日志管理这一块,就如下图所示:
可以看到基本上日志这一块都是会显示访问设备的ip地址的,所以自己今天也是尝试了一下,试了一下,发现还是比较简单的,中间也出现了一些小的问题,我也会在下面提到.希望能够对你有帮助.
不说废话,直接上代码
2.步骤
2.1设备ip
2.1.1首先创建获取ip地址的工具类IpUtil
package ams.web.device.util; import lombok.extern.slf4j.Slf4j; import javax.servlet.http.HttpServletRequest; import java.net.*; import java.util.Enumeration; @Slf4j public class IpUtil { private static final String LOCAL_IP = "127.0.0.1"; /** * 获取IP地址 * * 使用Nginx等反向代理软件， 则不能通过request.getRemoteAddr()获取IP地址 * 如果使用了多级反向代理的话，X-Forwarded-For的值并不止一个，而是一串IP地址，X-Forwarded-For中第一个非unknown的有效IP字符串，则为真实IP地址 */ public static String getIpAddr(HttpServletRequest request) { if (request == null) { return "unknown"; } 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("X-Forwarded-For"); } 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("X-Real-IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getRemoteAddr(); } return "0:0:0:0:0:0:0:1".equals(ip) ? LOCAL_IP : ip; } public static boolean internalIp(String ip) { boolean res = false; byte[] addr = textToNumericFormatV4(ip); if (addr != null && ip != null) { res = internalIp(addr) || LOCAL_IP.equals(ip); } return res; } private static boolean internalIp(byte[] addr) { final byte b0 = addr[0]; final byte b1 = addr[1]; // 10.x.x.x/8 final byte SECTION_1 = 0x0A; // 172.16.x.x/12 final byte SECTION_2 = (byte) 0xAC; final byte SECTION_3 = (byte) 0x10; final byte SECTION_4 = (byte) 0x1F; // 192.168.x.x/16 final byte SECTION_5 = (byte) 0xC0; final byte SECTION_6 = (byte) 0xA8; boolean flag = false; switch (b0) { case SECTION_1: flag = true; break; case SECTION_2: if (b1 >= SECTION_3 && b1 <= SECTION_4) { flag = true; } break; case SECTION_5: if (b1 == SECTION_6) { flag = true; } break; default: break; } return flag; } /** * 将IPv4地址转换成字节 *IPv4地址 * @param text * @return byte 字节 */ public static byte[] textToNumericFormatV4(String text) { if (text.length() == 0) { return null; } byte[] bytes = new byte[4]; String[] elements = text.split("\\.", -1); try { long l; int i; switch (elements.length) { case 1: l = Long.parseLong(elements[0]); if ((l < 0L) || (l > 4294967295L)) return null; bytes[0] = (byte) (int) (l >> 24 & 0xFF); bytes[1] = (byte) (int) ((l & 0xFFFFFF) >> 16 & 0xFF); bytes[2] = (byte) (int) ((l & 0xFFFF) >> 8 & 0xFF); bytes[3] = (byte) (int) (l & 0xFF); break; case 2: l = Integer.parseInt(elements[0]); if ((l < 0L) || (l > 255L)) return null; bytes[0] = (byte) (int) (l & 0xFF); l = Integer.parseInt(elements[1]); if ((l < 0L) || (l > 16777215L)) return null; bytes[1] = (byte) (int) (l >> 16 & 0xFF); bytes[2] = (byte) (int) ((l & 0xFFFF) >> 8 & 0xFF); bytes[3] = (byte) (int) (l & 0xFF); break; case 3: for (i = 0; i < 2; ++i) { l = Integer.parseInt(elements[i]); if ((l < 0L) || (l > 255L)) return null; bytes[i] = (byte) (int) (l & 0xFF); } l = Integer.parseInt(elements[2]); if ((l < 0L) || (l > 65535L)) return null; bytes[2] = (byte) (int) (l >> 8 & 0xFF); bytes[3] = (byte) (int) (l & 0xFF); break; case 4: for (i = 0; i < 4; ++i) { l = Integer.parseInt(elements[i]); if ((l < 0L) || (l > 255L)) return null; bytes[i] = (byte) (int) (l & 0xFF); } break; default: return null; } } catch (NumberFormatException e) { log.error("数字格式化异常",e); return null; } return bytes; } public static String getLocalIP() { String ip = ""; if (System.getProperty("os.name").toLowerCase().startsWith("windows")) { InetAddress addr; try { addr = InetAddress.getLocalHost(); ip = addr.getHostAddress(); } catch (UnknownHostException e) { log.error("获取失败",e); } return ip; } else { try { Enumeration<?> e1 = (Enumeration<?>) NetworkInterface .getNetworkInterfaces(); while (e1.hasMoreElements()) { NetworkInterface ni = (NetworkInterface) e1.nextElement(); if (!ni.getName().equals("eth0")) { continue; } else { Enumeration<?> e2 = ni.getInetAddresses(); while (e2.hasMoreElements()) { InetAddress ia = (InetAddress) e2.nextElement(); if (ia instanceof Inet6Address) continue; ip = ia.getHostAddress(); return ip; } break; } } } catch (SocketException e) { log.error("获取失败",e); } } return ""; } }
2.1.2在controller中测试使用
@GetMapping("/testipaddress") public String queryAllByHour(HttpServletRequest request) { String ip = IpUtil.getIpAddr(request); return ip; }
这样我们便能获取到访问接口设备的ip地址了.
为了测试他的真实性,我通过电脑和手机分别访问了一下我的接口,发现的确是能够识别的,如下图所示:
电脑访问接口:
手机访问接口:
数据库中插入的数据:
可以看到这里的确将设备的ip地址读取到了.
有一个 小BUG ,但是大家仔细看时间那一块会发现,好像上面的时间都比最下的一个时间慢了8个小时,这个主要是我们设置的时区有问题,修改application.yaml文件中这两处配置即可解决问题:
datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://ip地址:3306/数据库?useUnicode=true&serverTimezone=GMT%2B8&characterEncoding=utf-8#serverTimezone修改成东八区即可 jackson: time-zone: GMT+8
获取到设备的IP地址之后,我又想了想能不能获取到设备类型了,查阅了网上的资料发现,spring已经帮我们集成好了一个插件,我们引用进来,配置一下就可以直接用了,不多说了,spring牛逼.
2.2设备类型
2.2.1导入依赖
<dependency> <groupId>org.springframework.mobile</groupId> <artifactId>spring-mobile-device</artifactId> <version>1.1.3.RELEASE</version> </dependency>
2.2.2将Bean注入spring容器之中
一般是在你的MVC配置文件添加以下代码
@Bean public DeviceResolverHandlerInterceptor deviceResolverHandlerInterceptor() { return new DeviceResolverHandlerInterceptor(); } @Bean public DeviceHandlerMethodArgumentResolver deviceHandlerMethodArgumentResolver() { return new DeviceHandlerMethodArgumentResolver(); } @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new DeviceResolverHandlerInterceptor()); } @Override public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) { argumentResolvers.add(new DeviceHandlerMethodArgumentResolver()); }
2.2.3编写获取设备类型的工具类DeviceUtil
import org.springframework.mobile.device.Device; public class DeviceUtil { public static String getdevice(Device device){ if (device.isMobile()) { System.out.println("========请求来源设备是手机！========"); return "手机"; } else if (device.isTablet()) { System.out.println("========请求来源设备是平板！========"); return "平板"; } else if(device.isNormal()){ System.out.println("========请求来源设备是PC！========"); return "PC"; }else { System.out.println("========请求来源设备是其它！========"); return "其他"; } } }
2.2.4在controller中测试
@GetMapping("/testdevice") public String testdevice(Device device) { String name=DeviceUtil.getdevice(device); return name; }
