无法通过Olap4J API连接到OLAP多维数据集

我尝试使用Olap4J连接到OLAP多维数据集。我正在使用jdk14和olap4j-1.0.0.445.jar。我知道服务器和目录的IP地址。但我无法连接。以下异常似乎是最大的问题：

Server returned HTTP response code: 401 for URL: http://xx.xx.xx.xxx/olap/msmdpump.dll

我的请求中是否遗漏了某种身份验证信息，或者我错过了一些更基本的信息？

连接： 

try {
            Class.forName("org.olap4j.driver.xmla.XmlaOlap4jDriver");

        OlapConnection con;
        try {
            con = (OlapConnection) DriverManager.getConnection("jdbc:xmla:Server=http://xx.xx.xx.xxx/olap/msmdpump.dll;Catalog=xxx");

            OlapWrapper wrapper = con;
            OlapConnection olapConnection = wrapper.unwrap(OlapConnection.class);
            OlapStatement stmt = olapConnection.createStatement();
            olapConnection.setCatalog("Analysis Services Tutorial");

            stmt.executeOlapQuery("SELECT {[Customer].[City]} ON Rows FROM [Internet Sales] ");


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


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

我和你的问题一样。我想连接到我的OLAP多维数据集，该多维数据集托管在localhost中。

我注意到当我在浏览器中向http://192.168.0.151/OLAP/msmdpump.dll发送GET请求时，我需要输入用户名和密码。我想可能是我的驱动程序无法访问此资源。啊哈！我是对的;）

所以我想最简单的解决方案如下：尝试设置匿名IIS身份验证。我知道这不是最好的选择，但是当你想要开始使用OLAP时它就可以工作了。

我的工作连接字符串：

 Connection connection = DriverManager.getConnection(
"jdbc:xmla: Server=http://192.168.0.151/OLAP/msmdpump.dll;" +
"Data Source=http://192.168.0.151/OLAP/msmdpump.dll;" +
"Initial Catalog=AdventureWorksDW2014; " +
"Integrated Security=Basic; " +
"User ID=XXX; " +
"Password=XXX;");

用户ID - 它是一个db用户名 密码 - 这是db用户名的密码

更多的一点 - 我怀疑你的olap查询它不是一个正确的mdx查询所以你可能会得到OlapException。

祝你好运！
