个人网站性能优化经历（10）网站增加访客记录

自己搭建了一个基于SpringBoot+Spring Security+MyBatis+MySQL+Redis+Thymeleaf的博客网站
上线个人云服务器后，发现服务器访问慢。个人服务器是1核2G的，1M宽带，虽然服务器是低配的，但是可以通过优化代码，中间件等手段，来提升性能。

这篇主要讲网站增加访客记录的功能

1、设计表字段，新增visit表

id主键，city城市，url访问博客的url，visTime访问时间，browserType浏览器类型（360浏览器，谷歌浏览器，百度浏览器，IE浏览器），platformType平台类型（安卓，苹果，电脑）

2、建表语句

CREATE TABLE `visit` (`id` int(11) NOT NULL AUTO_INCREMENT,`ip` varchar(255) DEFAULT NULL,`city` varchar(255) DEFAULT NULL,`url` varchar(255) DEFAULT NULL,`visitTime` varchar(255) DEFAULT NULL,`browserType` varchar(255) DEFAULT NULL,`platformType` varchar(255) DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=16081 DEFAULT CHARSET=utf8;

3、实体类

@Data
public class Visit {private Integer id;private String ip;private String city;private String url;private String visitTime;private String browserType;//浏览器类型private String platformType;//平台类型public Visit(){}public Visit(String browserType, String platformType){this.browserType = browserType;this.platformType = platformType;}}

4、写个根据IP地址获取详细的地域信息的工具类

http://ip.taobao.com/service/getIpInfo.php 这个调用淘宝的访问ip具体信息的工具类，调完这个接口，对结果进行封装，地区划分国家，省份，城市（其中，对编码unicode设置为中文的）

package com.zxl.utils;import org.apache.commons.lang.StringUtils;import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.URL;/*** 根据IP地址获取详细的地域信息*/
public class AddressUtil {public String getAddresses(String content, String encodingString)throws UnsupportedEncodingException {String urlStr = "http://ip.taobao.com/service/getIpInfo.php";String returnStr = this.getResult(urlStr, content, encodingString);if (returnStr != null) {// 处理返回的省市区信息//System.out.println(returnStr);String[] temp = returnStr.split(",");if (temp.length <= 3) {return "未知城市";  // 无效IP，局域网测试}String country = (temp[2].split(":"))[1].replaceAll("\"", "");country = decodeUnicode(country);// 国家if (country.equals("XX") || country == "") {country = "";}String province = (temp[4].split(":"))[1].replaceAll("\"", "");province = decodeUnicode(province);// 省份if (province.equals("XX") || province == "") {province = "";} else {province = province + "省";}String area = (temp[3].split(":"))[1].replaceAll("\"", "");area = decodeUnicode(area);// 地区if (area.equals("XX") || StringUtils.isEmpty(area)) {area = "";} else {area = area + "区/县";}String city = (temp[5].split(":"))[1].replaceAll("\"", "");city = decodeUnicode(city);// 城市if (city.equals("XX") || city == "" || city.equals("内网IP")) {city = "";} else {city = city + "市";}String isp = (temp[7].split(":"))[1].replaceAll("\"", "");isp = decodeUnicode(isp);// ISPif (isp.equals("XX") || isp == "") {isp = "";}String str = province + city + isp;if (str.equals("") || str == "") {str = country;} else {str = province + city + area + " " + isp;}return str;}return "未知城市";}private String getResult(String urlStr, String content, String encoding) {URL url = null;HttpURLConnection connection = null;try {url = new URL(urlStr);connection = (HttpURLConnection) url.openConnection();// 新建连接实例connection.setConnectTimeout(2000);// 设置连接超时时间，单位毫秒connection.setReadTimeout(2000);// 设置读取数据超时时间，单位毫秒connection.setDoOutput(true);// 是否打开输出流 true|falseconnection.setDoInput(true);// 是否打开输入流true|falseconnection.setRequestMethod("POST");// 提交方法POST|GETconnection.setUseCaches(false);// 是否缓存true|falseconnection.connect();// 打开连接端口DataOutputStream out = new DataOutputStream(connection.getOutputStream());// 打开输出流往对端服务器写数据out.writeBytes(content);// 写数据,也就是提交你的表单 name=xxx&pwd=xxxout.flush();// 刷新out.close();// 关闭输出流BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), encoding));// 往对端写完数据对端服务器返回数据// ,以BufferedReader流来读取StringBuffer buffer = new StringBuffer();String line = "";while ((line = reader.readLine()) != null) {buffer.append(line);}reader.close();return buffer.toString();} catch (IOException e) {e.printStackTrace();} finally {if (connection != null) {connection.disconnect();// 关闭连接}}return "";}/*** unicode 转换成 中文*/public static String decodeUnicode(String theString) {char aChar;int len = theString.length();StringBuffer outBuffer = new StringBuffer(len);for (int x = 0; x < len; ) {aChar = theString.charAt(x++);if (aChar == '\\') {aChar = theString.charAt(x++);if (aChar == 'u') {int value = 0;for (int i = 0; i < 4; i++) {aChar = theString.charAt(x++);switch (aChar) {case '0':case '1':case '2':case '3':case '4':case '5':case '6':case '7':case '8':case '9':value = (value << 4) + aChar - '0';break;case 'a':case 'b':case 'c':case 'd':case 'e':case 'f':value = (value << 4) + 10 + aChar - 'a';break;case 'A':case 'B':case 'C':case 'D':case 'E':case 'F':value = (value << 4) + 10 + aChar - 'A';break;default:throw new IllegalArgumentException("Malformed      encoding.");}}outBuffer.append((char) value);} else {if (aChar == 't') {aChar = '\t';} else if (aChar == 'r') {aChar = '\r';} else if (aChar == 'n') {aChar = '\n';} else if (aChar == 'f') {aChar = '\f';}outBuffer.append(aChar);}} else {outBuffer.append(aChar);}}return outBuffer.toString();}}

5、编写个IP工具类，用来获取IP信息

public class IpUtil {// 获取IPpublic static String getIp(HttpServletRequest httpRequest) {String ipAddress = httpRequest.getHeader("x-forwarded-for");if (ipAddress == null || ipAddress.length() == 0|| "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = httpRequest.getHeader("Proxy-Client-IP");}if (ipAddress == null || ipAddress.length() == 0|| "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = httpRequest.getHeader("WL-Proxy-Client-IP");}if(null == ipAddress || 0 == ipAddress.length() || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = httpRequest.getHeader("X-Real-IP");}if (ipAddress == null || ipAddress.length() == 0|| "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = httpRequest.getRemoteAddr();if (ipAddress.equals("127.0.0.1")|| ipAddress.equals("0:0:0:0:0:0:0:1")) {// 根据网卡取本机配置的IPInetAddress inet = null;try {inet = InetAddress.getLocalHost();} catch (UnknownHostException e) {e.printStackTrace();}ipAddress = inet.getHostAddress();}}// 对于通过多个代理的情况，第一个IP为客户端真实IP,多个IP按照','分割if (ipAddress != null && ipAddress.length() > 15) { // "***.***.***.***".length()// = 15if (ipAddress.indexOf(",") > 0) {ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));}}return ipAddress;}}

6、新增访客记录方法

接下来就是具体的操作了，每次访问文章的时候，调insert方法，这个insert方法就是把访客的ip，地址，访问的文章等信息插入到visit这个表里

public void insert(HttpServletRequest request){Visit visit = new Visit();visit.setIp(IpUtil.getIp(request));TimeUtil timeUtil = new TimeUtil();visit.setVisitTime(timeUtil.getFormatDateForSix());int visitTimes = visitMapper.findVisitTimes(timeUtil.getFormatDateForThree(), IpUtil.getIp(request));String userAgent = request.getHeader("user-agent");try{if (visitTimes == 0) {visit.setPlatformType(UserAgentUtil.getUserAgent(userAgent).getPlatformType());visit.setBrowserType(UserAgentUtil.getUserAgent(userAgent).getBrowserType());visit.setUrl(request.getRequestURL().toString());visit.setCity(new AddressUtil().getAddresses("ip="+ visit.getIp(), "utf-8"));visitMapper.insert(visit);}}catch (Exception e){e.printStackTrace();}
}

插入成功

总结：

每次访问首页，文章的时候，都可以调用新增访客记录的方法，这个功能就类似于QQ空间的访客记录。现在很多网站都会有访客记录，有些是用户可以看到，有些只有管理员才能看到。
