How to use Java to implement the visitor statistics function of CMS system

With the development and popularization of the Internet, more and more people are beginning to use CMS (content management system) to build and manage their own websites. As one of the important functions, visitor statistics play a vital role in website operation and analysis. This article will introduce how to use Java to implement the visitor statistics function of the CMS system.

1. Requirements Analysis

Before implementing the visitor statistics function, we need to clarify the specific requirements. Usually, the information required for visitor statistics includes the visitor's IP address, access time, visited pages, etc. At the same time, we also need to determine the visitor's geographical location based on the visitor's IP address. Based on these requirements, we will introduce how to implement it step by step.

2. Obtain the visitor’s IP address

First, we need to obtain the visitor’s IP address. In Java, the visitor's IP address can be obtained by using the HttpServletRequest object. The following is a sample code:

import javax.servlet.http.HttpServletRequest;

// 获取访客IP地址
public String getIpAddress(HttpServletRequest request) {
    String ipAddress = request.getHeader("x-forwarded-for");
    if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
        ipAddress = request.getHeader("Proxy-Client-IP");
    }
    if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
        ipAddress = request.getHeader("WL-Proxy-Client-IP");
    }
    if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
        ipAddress = request.getRemoteAddr();
    }
    return ipAddress;
}

3. Record access information

After obtaining the visitor's IP address, we need to store the access information in the database. First, we need to create a table to store access information. Assume that our data table is named "visitor_stats" and includes the following fields: id (visit record ID), ip (visitor IP address), time (visit time), page (visit page).

In Java, we can use JDBC to connect to the database and execute SQL statements to insert data. The following is a sample code:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;

// 记录访问信息
public void recordVisitor(String ip, String time, String page) {
    Connection conn = null;
    PreparedStatement stmt = null;
    try {
        Class.forName("com.mysql.jdbc.Driver");
        conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/cms", "root", "password");
        String sql = "INSERT INTO visitor_stats (ip, time, page) VALUES (?, ?, ?)";
        stmt = conn.prepareStatement(sql);
        stmt.setString(1, ip);
        stmt.setString(2, time);
        stmt.setString(3, page);
        stmt.executeUpdate();
    } catch (ClassNotFoundException | SQLException e) {
        e.printStackTrace();
    } finally {
        try {
            if (stmt != null) stmt.close();
            if (conn != null) conn.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

4. Obtain the accessed page

After obtaining the visitor's IP address, we also need to obtain the information of the accessed page. In Java, you can get the URL of the accessed page by using the HttpServletRequest object. The following is a sample code:

import javax.servlet.http.HttpServletRequest;

// 获取访问页面
public String getPage(HttpServletRequest request) {
    String page = request.getRequestURL().toString();
    return page;
}

5. Determine the visitor’s geographical location

After obtaining the visitor’s IP address, we can obtain the visitor’s location by calling the third-party IP address query API location information. Taking Baidu Map's IP address query API as an example, the following is the sample code:

import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import java.io.IOException;

// 判断访客地理位置
public String getLocation(String ip) {
    String url = "https://api.map.baidu.com/location/ip?ak=your_ak&ip=" + ip;
    String location = "";
    CloseableHttpClient httpClient = null;
    try {
        httpClient = HttpClients.createDefault();
        HttpGet httpGet = new HttpGet(url);
        String result = EntityUtils.toString(httpClient.execute(httpGet).getEntity());
        // 解析结果并获取地理位置信息
        // ...
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            if (httpClient != null) httpClient.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return location;
}
