java - Java 和 Hyper-V

Question

我正在尝试学习一些关于 JAVA 的知识，而最好的方法是创建一些我会实际使用并知道它的目的是什么的东西。我正在尝试与 HyperV（WMI 库）通信。

例如我发现了以下内容，我的问题是：如何使用它？我正在使用 Netbeans 创建 GUI。

另外，如何将 jInterop 加载到我的项目中以便我可以使用它？

谢谢你。

您可以使用 JInterop 来管理 HyperV 的所有操作。从这里
下载 JInterop 。 将所有 JInterop jar 文件添加到您的项目构建路径。 以下是获取 Hyper 服务器所有虚拟机的示例：

public class ManageHyperV {
    static final int RETURN_IMMEDIATE = 0x10;
    static final int FORWARD_ONLY = 0x20;     
    private static final int STOP = 0;
    private static final int START = 1;
    static IJIDispatch msvmServices = null;


    private static IJIDispatch createCOMServer(String namespace) { //root//virtualization
        JIComServer comServer;
        try {           
            JISystem.getLogger().setLevel(Level.WARNING);
            JISystem.setAutoRegisteration(true);

            JISession session = JISession.createSession(domainName,userName,password);
            session.useSessionSecurity(false);
            comServer = new JIComServer(valueOf("WbemScripting.SWbemLocator"),hostIP,session);

            IJIDispatch wbemLocator = (IJIDispatch) narrowObject(comServer.createInstance().queryInterface(IID));
            //parameters to connect to WbemScripting.SWbemLocator
            Object[] params = new Object[] {
                    new JIString(hostIP),//strServer
                    new JIString(namespace),//strNamespace
                    //                  new JIString("ROOT\\CIMV2"),
                    JIVariant.OPTIONAL_PARAM(),//strUser 
                    JIVariant.OPTIONAL_PARAM(),//strPassword 
                    JIVariant.OPTIONAL_PARAM(),//strLocale 
                    JIVariant.OPTIONAL_PARAM(),//strAuthority
                    new Integer(0),//iSecurityFlags 
                    JIVariant.OPTIONAL_PARAM()//objwbemNamedValueSet
            };
            JIVariant results[] = wbemLocator.callMethodA("ConnectServer", params);
            IJIDispatch wbemServices = (IJIDispatch) narrowObject(results[0].getObjectAsComObject());
            return wbemServices;
        } catch (JIException jie) {
            System.out.println(jie.getMessage());
            jie.printStackTrace();
        } catch (JIRuntimeException jire) {
            jire.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    private static void getVMList() throws JIException {

            String temp = "select * from Msvm_ComputerSystem";          
            String[] arrQuery = new String[]{temp};

            for (int k=0;k<arrQuery.length;k++) {

                Object[] params = new Object[] {
                        new JIString(arrQuery[k]),
                        JIVariant.OPTIONAL_PARAM(),
                        new JIVariant(new Integer(RETURN_IMMEDIATE + FORWARD_ONLY))
                };

                JIVariant[] servicesSet = msvmServices.callMethodA("ExecQuery", params);
                iterateEnum(servicesSet);

            }       
    }

    private  static void iterateEnum(JIVariant[] servicesSet) {
        try {
            IJIDispatch wbemObjectSet = (IJIDispatch) narrowObject(servicesSet[0].getObjectAsComObject());
            JIVariant newEnumvariant = wbemObjectSet.get("_NewEnum");
            IJIComObject enumComObject = newEnumvariant.getObjectAsComObject();
            IJIEnumVariant enumVariant = (IJIEnumVariant) narrowObject(enumComObject.queryInterface(IJIEnumVariant.IID));
            List<Object[]> respArr = getEnumIterations(enumVariant);

            for (Object[] elements : respArr) {
                JIArray aJIArray = (JIArray) elements[0];
                JIVariant[] array = (JIVariant[]) aJIArray.getArrayInstance();

                for (JIVariant variant : array) {
                    IJIDispatch wbemObjectDispatch = (IJIDispatch) narrowObject(variant.getObjectAsComObject());

                    JIVariant[] v = wbemObjectDispatch.callMethodA("GetObjectText_", new Object[] {});
                    System.out.println("----------------------------------------------------------------------");
                    System.out.println(v[0].getObjectAsString().getString());
                    System.out.println("----------------------------------------------------------------------");
                }
            }

            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {    
        msvmServices = createCOMServer("root\\virtualization");
        getVMList();
    }

}

private static List<Object[]> getEnumIterations(IJIEnumVariant enumVariant) {
    List<Object[]> list = new ArrayList<Object[]>(); 
    int i=0;

    for (i=0;i<100;i++) {
        try {
            list.add(enumVariant.next(1));

}

另外，提供管理员用户名和密码。
它应该工作。
谢谢。
