QT_BEGIN_NAMESPACE

#define IBasicModule_iid "com.twsz.tc.ningjian.IBasicModule/1.0"

Q_DECLARE_INTERFACE(IBasicModule, IBasicModule_iid)

QT_END_NAMESPACE

//Q_DECLARE_INTERFACE(IBasicModule,"com.twsz.tc.ningjian.IBasicModule/1.0");

#endif // BASIC_MODULE_INTERFACE_H

基本是純虛類要在末尾添加

Q_DECLARE_INTERFACE(IBasicModule, IBasicModule_iid) 即可

2、實現插件
頭文件 如下：  cpp正常就好了，注意要繼承QObject 和 接口類就可以了，還要在在頭文件中添加

    Q_OBJECT

    Q_PLUGIN_METADATA(IID "com.twsz.tc.ningjian.IBasicModule/1.0" )

    Q_INTERFACES(IBasicModule)
在項目屬性中要添加

TEMPLATE = lib

CONFIG += plugin

#ifndef STT_BASIC_MOUDLE_H

Q_OBJECT
Q_PLUGIN_METADATA(IID "com.twsz.tc.ningjian.IBasicModule/1.0" )
Q_INTERFACES(IBasicModule)

std::string get_stt_variable(int test_id,std::string key);

void add_fun(const char * moudle_name,const char * fun_name ,const char * fun_describe);

#endif // STT_BASIC_MOUDLE_H

3、使用插件

下面是遍歷加載plugins目錄下所有實現 IBasicModule 接口的插件 獲取相應的實例就可以調用了
頭文件記得添加
#include <QPluginLoader>

//注冊模塊指令
QDir plugindir = QDir(QDir::currentPath()+"/plugins");
int i = 0;
foreach(QString filename,plugindir.entryList(QDir::Files)){
QPluginLoader loader(plugindir.absoluteFilePath(filename));
if (IBasicModule * base_moudle = qobject_cast<IBasicModule *>(loader.instance()))
{
qDebug()<<base_moudle->get_moudle_name().c_str();

STT_Global::basicModule_map.insert(std::pair<std::string,IBasicModule*>(base_moudle->get_moudle_name(),base_moudle));
STT_Global::PlugsList.push_back( base_moudle->get_moudle_name());
base_moudle->init(G_Test_Info,G_Test_Fun_Info,G_Moudles_Config,G_STT_Run_Fun);
base_moudle->reg_fun(-1,G_STT_Interpreter[-1]);
base_moudle->reg_ui_fun(G_Reg_UI_FUN);
i++;
emit STT_Global::fl->signal_process(20+ 80 * i / plugindir.entryList(QDir::Files).size());
}
}
