如何在执行JDBC语句时收集警告/通知？

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

public class JDBCWarningExample {
    public static void main(String[] args) {
        try {
            // 加载数据库驱动
            Class.forName("com.mysql.jdbc.Driver");
            
            // 创建连接
            Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");
            
            // 设置警告处理器
            connection.setWarningListener(new SQLWarningListener());
            
            // 创建预编译语句
            PreparedStatement statement = connection.prepareStatement("SELECT * FROM mytable");
            
            // 执行查询
            statement.executeQuery();
            
            // 获取警告信息
            SQLWarning warning = connection.getWarnings();
            while (warning != null) {
                System.out.println("Warning: " + warning.getMessage());
                warning = warning.getNextWarning();
            }
            
            // 关闭连接
            connection.close();
        } catch (ClassNotFoundException | SQLException e) {
            e.printStackTrace();
        }
    }
}

class SQLWarningListener implements SQLWarningListener {
    @Override
    public void warningOccurred(SQLWarning warning) {
        System.out.println("Warning occurred: " + warning.getMessage());
    }
}
