篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了个人网站性能优化经历（10）网站增加访客记录相关的知识，希望对你有一定的参考价值。
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);// ISP
if (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|false
connection.setDoInput(true);// 是否打开输入流true|false
connection.setRequestMethod("POST");// 提交方法POST|GET
connection.setUseCaches(false);// 是否缓存true|false
connection.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=xxx
out.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IP
public 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IP
InetAddress 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()
// = 15
if (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(n以上是关于个人网站性能优化经历（10）网站增加访客记录的主要内容，如果未能解决你的问题，请参考以下文章
