多线程下tcp收数据，接收到的数据类型为泛型数据T，将收到的数据通过Qvetor<T>发送给主线程，其中T是自定义类型。主线程收数据，收到的数据放入QMap<QString,QVctor<T>>中，根据不同的QString和T类型分类数据，比较同一个Map中数据的一致性，思考一下，请用qt写一段代码，代码包含.h和.cpp。

以下是示例代码：

datareceiver.h

#ifndef DATARECEIVER_H
#define DATARECEIVER_H

#include <QObject>
#include <QVector>

template<typename T>
class DataReceiver : public QObject
{
    Q_OBJECT
public:
    explicit DataReceiver(QObject *parent = nullptr);

signals:
    void dataReceived(const QString& key, const QVector<T>& data);

public slots:
    void receiveData(const T& data, const QString& key);

private:
    QMap<QString, QVector<T>> m_dataMap;
};

template<typename T>
DataReceiver<T>::DataReceiver(QObject *parent) : QObject(parent)
{

}

template<typename T>
void DataReceiver<T>::receiveData(const T& data, const QString& key)
{
    if (!m_dataMap.contains(key)) {
        m_dataMap.insert(key, QVector<T>());
    }
    m_dataMap[key].append(data);
    emit dataReceived(key, m_dataMap[key]);
}

#endif // DATARECEIVER_H

datareceiver.cpp

#include "datareceiver.h"

template<typename T>
DataReceiver<T>::DataReceiver(QObject *parent) : QObject(parent)
{

}

template<typename T>
void DataReceiver<T>::receiveData(const T& data, const QString& key)
{
    if (!m_dataMap.contains(key)) {
        m_dataMap.insert(key, QVector<T>());
    }
    m_dataMap[key].append(data);
    emit dataReceived(key, m_dataMap[key]);
}

main.cpp

#include <QCoreApplication>
#include <QDebug>
#include <QThread>
#include <QMap>
#include "datareceiver.h"

struct MyData {
    int value1;
    QString value2;
};

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

    DataReceiver<MyData> receiver;
    QMap<QString, QVector<MyData>> dataMap;

    QObject::connect(&receiver, &DataReceiver<MyData>::dataReceived, [&](const QString& key, const QVector<MyData>& data) {
        dataMap[key] = data;
        qDebug() << "Data received for key" << key << ":" << data.size();
    });

    QThread thread;
    thread.start();

    for (int i = 0; i < 100; ++i) {
        MyData data = { i, "test" };
        receiver.moveToThread(&thread);
        QMetaObject::invokeMethod(&receiver, "receiveData", Qt::QueuedConnection,
                                  Q_ARG(MyData, data), Q_ARG(QString, "key"));
    }

    thread.quit();
    thread.wait();

    qDebug() << "Data map size:" << dataMap.size();

    return a.exec();
}
