 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

基本是纯虚类要在末尾添加

Q_DECLARE_INTERFACE(IBasicModule, IBasicModule_iid) 即可

2、实现插件
头文件 如下：  cpp正常就好了，注意要继承QObject 和 接口类就可以了，还要在在头文件中添加

    Q_OBJECT

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

    Q_INTERFACES(IBasicModule)
在项目属性中要添加

TEMPLATE = lib

CONFIG += plugin

 #ifndef STT_BASIC_MOUDLE_H
 #define STT_BASIC_MOUDLE_H

 #include <Basic_Module_Interface.h>
 #include <iostream>
 #include <QScriptEngine>
 #include <QScriptValue>
 #include <QtCore/QtPlugin>

 #include <iostream>
 using namespace std;

 class  STT_Basic_Moudle:public QObject,public IBasicModule
 {
     Q_OBJECT
     Q_PLUGIN_METADATA(IID "com.twsz.tc.ningjian.IBasicModule/1.0" )
     Q_INTERFACES(IBasicModule)

 public:
     STT_Basic_Moudle();
     // IBasicModule interface
 public:

 void set_stt_variable(int test_id,std::string key,std::string value);
 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

下面是遍历加载plugins目录下所有实现 IBasicModule 接口的插件 获取相应的实例就可以调用了
头文件记得添加

#include <QPluginLoader>

     //注册模块指令
     QDir plugindir = QDir(QDir::currentPath()+"/plugins");
     int i = ;
     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(-,G_STT_Interpreter[-]);
             base_moudle->reg_ui_fun(G_Reg_UI_FUN);
             i++;
             emit STT_Global::fl->signal_process(+  * i / plugindir.entryList(QDir::Files).size());
         }
     }
