使用Qt5.10.1制作javaweb项目的壳子 webenginewidgets、QWebChannel、QMediaPlayer

Qt的安装和环境配置这里就不说了，度娘都有。废话不多说，直接上代码。
baise.pro文件中加入：
QT += webenginewidgets //窗口引擎部件（浏览器必须的）
QT += multimedia //媒体部件（需要用到MP3播放的可以加）
SOURCES +=
main.cpp
mainwindow.cpp
swebengineview.cpp
HEADERS +=
mainwindow.h
swebengineview.h
FORMS +=
mainwindow.ui
DISTFILES +=
RESOURCES +=
logo.qrc //logo图片的配置文件

mainwindow.h

main.cpp

#include "mainwindow.h"

{QApplication a(argc, argv);MainWindow w;w.setWindowState(Qt::WindowMaximized);//设置窗体默认最大w.setWindowFlags(Qt::FramelessWindowHint);//无边框w.show();return a.exec();
}

swebengineview.h

#ifndef SWEBENGINEVIEW_H
#define SWEBENGINEVIEW_H
#include <QWidget>
#include <QWebEngineView>class SWebEngineView : public QWebEngineView
{Q_OBJECT
public:explicit SWebEngineView(QWidget *parent = 0);

}

因为javaweb项目的访问地址可能会变，所以将项目的访问路径写到配置中，通过配置可以灵活的改变需要访问项目。Config.ini的配置文件很简单，就一个路径的配置：
[url]
baise=http://localhost:8080/baise_new
Config.ini文件放到项目的Qt项目的运行目录下：

图标右上角的两个图标就是窗体最小化和关闭的。
页面js调用qt的代码：

<script src="<%=path%>/js/qwebchannel.js"></script>//qt的js必须引入的
<script>//调用Qt的窗体播报语音function _player(mp3Url) {new QWebChannel(qt.webChannelTransport,function(channel) {window.bound = channel.objects.bound;               bound.jsPlayer(mp3Url, Math.random());});}//调用Qt的窗体隐藏和关闭功能function _close1() {new QWebChannel(qt.webChannelTransport,function(channel) {window.bound = channel.objects.bound;               bound.jsCloseQt();});}function _minimized1() {new QWebChannel(qt.webChannelTransport,function(channel) {window.bound = channel.objects.bound;               bound.jsMinimizedQt();});}</script>下面是html图片按钮：
<div id="video" style="width:120px;height:40px;"><img src="<%=path%>/images/min.png" onclick="_minimized()"/><img src="<%=path%>/images/closing.png" onclick="_close()"/>
</div>
