我正在尝试学习有关JAVA的知识,而做到这一点的最佳方法是创建我会实际使用的东西,并了解它的目的。
我正在尝试与HyperV(WMI库)进行通信。
例如,我发现以下内容,我的问题是:如何使用它?我正在使用Netbeans创建GUI。
http://www.paulneve.com/wlab/javadoc/org/paulneve/wlab/virtualisation/VirtualisationAccessHyperVImpl.html
另外,如何将jInterop加载到我的项目中以便可以使用它?
谢谢。
最佳答案
您可以使用JInterop来管理HyperV的所有操作。
从here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服务器的所有VM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("----------------------------------------------------------------------");
}
}
} catch (JIRuntimeException e) {
e.printStackTrace();
} catch (JIException e) {
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));
}catch (JIRuntimeException jre) {
break;
}
catch (JIException jie) {
break;
}
catch (Exception e) {
break;
}
}
return list;
}
另外,提供管理员用户名和密码。
它应该工作。
谢谢。
