我想要跟踪一个Java函数被调用的次数，并将其保存在数据库中。做到这一点的最好方法是什么？

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

public class FunctionTracker {
    private static final String DB_URL = "jdbc:mysql://localhost:3306/mydatabase";
    private static final String DB_USERNAME = "username";
    private static final String DB_PASSWORD = "password";

    public static void main(String[] args) {
        // 连接数据库
        try (Connection connection = DriverManager.getConnection(DB_URL, DB_USERNAME, DB_PASSWORD)) {
            // 创建函数调用次数表（如果不存在）
            createTable(connection);

            // 跟踪函数调用次数
            trackFunctionCall(connection, "functionName");

            // 查询函数调用次数
            int callCount = getFunctionCallCount(connection, "functionName");
            System.out.println("函数被调用次数：" + callCount);
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    private static void createTable(Connection connection) throws SQLException {
        String createTableQuery = "CREATE TABLE IF NOT EXISTS function_calls (function_name VARCHAR(255) PRIMARY KEY, call_count INT)";
        try (PreparedStatement statement = connection.prepareStatement(createTableQuery)) {
            statement.executeUpdate();
        }
    }

    private static void trackFunctionCall(Connection connection, String functionName) throws SQLException {
        String incrementCountQuery = "INSERT INTO function_calls (function_name, call_count) VALUES (?, 1) " +
                "ON DUPLICATE KEY UPDATE call_count = call_count + 1";
        try (PreparedStatement statement = connection.prepareStatement(incrementCountQuery)) {
            statement.setString(1, functionName);
            statement.executeUpdate();
        }
    }

    private static int getFunctionCallCount(Connection connection, String functionName) throws SQLException {
        String getCountQuery = "SELECT call_count FROM function_calls WHERE function_name = ?";
        try (PreparedStatement statement = connection.prepareStatement(getCountQuery)) {
            statement.setString(1, functionName);
            try (ResultSet resultSet = statement.executeQuery()) {
                if (resultSet.next()) {
                    return resultSet.getInt("call_count");
                }
            }
        }
        return 0;
    }
}
