如何在使用最新的“MSAL”库而不是基于ADAL的情况下，通过Azure Web服务API在Azure服务器上创建区域DNS和记录？然而，DNS库支持https://github.com/Azure-Samples/dns-java-host-and-manage-your-domains，但未提到任何使用MSAL访问令牌的方式。例如，
    ApplicationTokenCredentials credentials = new ApplicationTokenCredentials(client, tenant, key, AzureEnvironment.AZURE);
    azure = Azure.authenticate(credentials).withSubscription(subscriptionId);
    ResourceGroup resourceGroup = azure.resourceGroups().define(rgName)
            .withRegion(Region.US_EAST2)
            .create();
    System.out.println("Creating root DNS zone " + customDomainName + "...");
    DnsZone rootDnsZone = azure.dnsZones().define(customDomainName)
            .withExistingResourceGroup(resourceGroup)
            .create();

How can we create zone DNS and records on Azure server using Azure web services API with latest &quot;MSAL&quot; library not ADAL based? However DNS library support https://github.com/Azure-Samples/dns-java-host-and-manage-your-domains does not mentioned any way to utilized using MSAL access token. For example
   	ApplicationTokenCredentials credentials = new ApplicationTokenCredentials(client, tenant, key, AzureEnvironment.AZURE);
	azure = Azure.authenticate(credentials).withSubscription(subscriptionId);
	ResourceGroup resourceGroup = azure.resourceGroups().define(rgName)
			.withRegion(Region.US_EAST2)
			.create();
	System.out.println(&quot;Creating root DNS zone &quot; + customDomainName + &quot;...&quot;);
	DnsZone rootDnsZone = azure.dnsZones().define(customDomainName)
			.withExistingResourceGroup(resourceGroup)
			.create();
But it is using with keys instead of access tokens provided by MSAL. This can be already achieved in old ways which is using ADAL internally by Azure.

If you want to use Azure java management SDK to manage Azure DNS with AD access token, please refer to the following code
a. create a service principal  (I use Azure CLI to do that)

[![enter image description here][1]][1]
2. Code

    AzureTokenCredentials tokenCredentials = new AzureTokenCredentials(AzureEnvironment.AZURE,ADProperty.tenantId) {
@Override
public String getToken(String resource) throws IOException {
String token =null;
// use msal to get Azure AD access token
ConfidentialClientApplication app = ConfidentialClientApplication.builder(
ADProperty.clientId,  // sp appid
ClientCredentialFactory.createFromSecret(ADProperty.clientKey)) // sp password
.authority(ADProperty.authority) // "https://login.microsoftonline.com/" + sp tenant id
.build();
ClientCredentialParameters clientCredentialParam = ClientCredentialParameters.builder(
Collections.singleton("https://management.azure.com/.default"))
.build();
CompletableFuture<IAuthenticationResult> future = app.acquireToken(clientCredentialParam);
try {
token =future.get().accessToken();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
return  token;
}
};
Azure azure = Azure.authenticate(tokenCredentials)
.withSubscription(ADProperty.subscriptionId); // sp subscription id
DnsZone rootDnsZone = azure.dnsZones().define("mydevchat.com")
.withExistingResourceGroup("jimtest")
.create();
System.out.println("create DNSZone " + rootDnsZone.name() + " successfully");
