如何使用QT & C++监听mysql数据库中的触发事件？

#include <QObject>
#include <QCoreApplication>
#include <QtSql>

class MySQLTriggerListener : public QObject
{
    Q_OBJECT

public slots:
    void handleTriggerEvent(const QString& event)
    {
        // 处理触发事件的逻辑
        qDebug() << "Trigger event received: " << event;
    }
};

void MySQLTriggerListener::connectAndListen()
{
    // 连接MySQL数据库
    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
    db.setHostName("localhost");
    db.setDatabaseName("your_database_name");
    db.setUserName("your_username");
    db.setPassword("your_password");

    if (!db.open()) {
        qDebug() << "Failed to connect to MySQL database";
        return;
    }

    // 注册触发事件的回调函数
    QSqlQuery query;
    query.exec("CREATE TRIGGER your_trigger_name AFTER INSERT ON your_table_name FOR EACH ROW "
               "BEGIN "
               "CALL handleTriggerEvent('insert'); "
               "END");

    if (query.lastError().isValid()) {
        qDebug() << "Failed to register trigger event: " << query.lastError().text();
        return;
    }

    qDebug() << "Trigger event registered";

    // 开始监听MySQL数据库的触发事件
    QCoreApplication::exec();
}

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    MySQLTriggerListener listener;
    listener.connectAndListen();

    return a.exec();
}
