Java-如何连接到Microsoft Office 365 SharePoint

Question

我需要通过公司防火墙连接到Office 365上的SharePoint 2010实例。我尝试使用java-sharepoint-library ：

NtlmAuthenticator credentials = new NtlmAuthenticator(
    "myactivedirectorydomain", "myusername", "mypassword"); 

HttpProxy httpProxy = new HttpProxy("proxy.ourcompany.com", 80);

SPSite site = new SPSite(
    new URL("https://ourcompany.com/sites/teams_MySandbox"), 
    credentials, 
    httpProxy, 
    true, 
    SPVersion.SP2010);

SPWeb rootWeb = site.getRootWeb(); //gives error below

这是我得到的错误：“服务器重定向太多次（20）”

我可能是错的，但我认为您遇到了Sharepoint Loopback检查问题：

尝试一种变通办法，请注意关闭它所涉及的安全问题。

我会暂时禁用它，只是为了检查是否确实是问题所在。
