浅析C++调用Java的Jar包(带参数)问题-C/C++开发

这篇文章主要介绍了C++调用Java的Jar包（带参数）问题，本文通过实例代码给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下

JarAppCall.h


#include <atlstr.h>

        CJarAppCall(void);

        @brief 运行Jar包调用，等待运行完毕返回
        @param[in] strJarDir jar包文件夹
        @param[in] strJarName jar包名称<br>　　　　　　　　　 @param[in] strParam 传入的参数
        @return 运行是否成功
        */
        bool Run(const CString& strJarDir, const CString& strJarName, const CString& strParam);
 
    private:
        bool CallApp(const CString& strJarName, const CString& strParam);
};

JarAppCall.cpp

    }
 
    // 等待程序结束
    WaitForSingleObject(pi.hProcess, INFINITE);
    CloseHandle(pi.hProcess);
    return true;
}
