QtService无法启动

Question

我QtService上课有问题.我正在尝试构建Windows服务.我下载了文件并将它们包含在我的项目中.

现在,当我运行项目时(在QtCreator中)我收到消息

服务MyService无法启动.

该方法start()未执行.

我在实现结束时在文件qtservice.cpp中找到了上层消息QtServiceBase::exec().

你知道我为什么收到这条消息吗？

myservice.h:

#ifndef MYSERVICE_H
#define MYSERVICE_H

#include <QtService/qtservice.h>
#include <QCoreApplication>
#include <QDebug>
#include <QObject>

class MyService : public QtService<QCoreApplication>
{
public:
    MyService(int argc, char **argv);
    ~MyService();
    void start();
    void pause();
    void resume();
    void stop();

private:

};

#endif // MYSERVICE_H

myservice.cpp:

#include "myservice.h"

MyService::MyService(int argc, char **argv) : QtService<QCoreApplication>(argc, argv, "MyService")
{
    qDebug() << "CONSTRUCTOR";
    setServiceDescription("This is my service. ");
    setServiceFlags(QtServiceBase::CanBeSuspended);
    qDebug() << "CONSTRUCTOR 1";

}

MyService::~MyService()
{
    qDebug() << "DECONSTRUCTOR";
    try {

    } catch (...) {
        qCritical() << "An unknown error occured in deconstructor";
    }
}

void MyService::start()
{
    qDebug() << "START";
    try {
        QCoreApplication *app = application();
        qDebug() << "Service started";
        qDebug() << app->applicationDirPath();
    } catch (...) {
        qCritical() << "An unknown error occured in start";
    }
}

void MyService::pause()
{
    qDebug() << "PAUSE";
    try {

        qDebug() << "Service paused";
    } catch (...) {
        qCritical() << "An unknown error occured in pause";
    }
}

void MyService::resume()
{
    qDebug() << "RESUME";
    try {

        qDebug() << "Service resumed";
    } catch (...) {
        qCritical() << "An unknown error occured in resume";
    }
}

void MyService::stop()
{
    qDebug() << "STOP";
    try {

        qDebug() << "Service stopped";
    } catch (...) {
        qCritical() << "An unknown error occured in stop";
    }
}

main.cpp:

#include "myservice.h"
#include <QCoreApplication>

int main(int argc, char *argv[])
{
    MyService service(argc, argv);
    return service.exec();
}

和.pro文件:

QT       += core gui network

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = ServiceTest
TEMPLATE = app


SOURCES += main.cpp\
        myservice.cpp

HEADERS  += myservice.h

include(QtService/qtservice.pri)

你有没有把论点-exec传给服务？(单击"项目",然后单击"运行设置",然后填写"参数"字段).

该服务希望作为服务运行,除非您传递-exec告诉它作为应用程序运行的参数(因此您可以对其进行调试).

其他的命令行参数-install,-uninstall,-pause,等你安装服务后用-install,那么你可以使用Windows管理工具运行它.
