Answer 1

As Suggested by Jatin . You could refer to Azure Active Directory authentication document , where you could find different authentication methods and below is the sample example of connecting Azure Active Directory with MSI authentication method.

import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;

import com.microsoft.sqlserver.jdbc.SQLServerDataSource;

public class AAD_MSI {
    public static void main(String[] args) throws Exception {

        SQLServerDataSource ds = new SQLServerDataSource();
        ds.setServerName("aad-managed-demo.database.windows.net"); // Replace with your server name
        ds.setDatabaseName("demo"); // Replace with your database name
        ds.setAuthentication("ActiveDirectoryMSI");
        // Optional
        ds.setMSIClientId("94de34e9-8e8c-470a-96df-08110924b814"); // Replace with Client ID of User-Assigned Managed Identity to be used

        try (Connection connection = ds.getConnection();
                Statement stmt = connection.createStatement();
                ResultSet rs = stmt.executeQuery("SELECT SUSER_SNAME()")) {
            if (rs.next()) {
                System.out.println("You have successfully logged on as: " + rs.getString(1));
            }
        }
    }
}
