您好我正在尝试通过olap4j连接到microsoft分析服务,但每次都出现此错误“org.olap4j.OlapException:此连接在执行查询时遇到异常”
错误的完整描述:

this is the connection function
<code>
public static OlapConnection getConnectionAServices() throws Exception {
Class.forName("org.olap4j.driver.xmla.XmlaOlap4jDriver");
// anonymous connection
Connection connectionXMLA = DriverManager.getConnection(
"jdbc:xmla:Server=http://localhost/olap/msmdpump.dll;" + "Catalog=Analysis_Service;");
OlapWrapper wrapper = (OlapWrapper) connectionXMLA;
OlapConnection olapConnection = wrapper.unwrap(OlapConnection.class);
return olapConnection;
}

您是否为IIS中的SQL Server Analysis Services设置了XML / A HTTP访问权限?
Configuring HTTP Access to SQL Server 2008 Analysis Services on Microsoft Windows Server 2008
您还需要在数据库中添加具有适当权限的角色,然后进行添加 您正在运行该应用程序的用户。
