需要独立的Java程序，便于使用KERBEROS身份验证将文件上传到Sharepoint。
我们有sharepoint服务器，它升级到2010版本并配置了Kerberos身份验证。早期的sharepoint版本使用的是NTLM身份验证，我有javaq客户端程序从本地系统上传文件。由于sharepoint通过Kerberos身份验证升级，我需要修改当前的NTLM版本化java程序以使用Kerberos。我获得了用于身份验证和连接的代码片段。我能够通过java程序读取Sharepoint URL并下载特定文件。现在我正在尝试将文件上传到Sharepoint，但没有获得所需的java类和jar文件。
我使用SPNEGO API进行Kerberos配置设置以连接sharepoint。
配置文件： 的krb5.conf login.conf
用于Kerberos Auth的API： spnego-r7.jar
连接： 以下代码我用于连接和文件下载，这是完美的工作。
spnego = new SpnegoHttpURLConnection("spnego-client", <<sharepoint_user>>, <<sharepoint_password>>);
//New Lines added to omit SSL Handshake exception
TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers(){
return null;
}
public void checkClientTrusted(java.security.cert.X509Certific ate[] certs, String authType){
//No need to implement.
}
public void checkServerTrusted(java.security.cert.X509Certific ate[] certs, String authType){
//No need to implement.
}
}
};
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.g etSocketFactory());
spnego.connect(new URL(spLocation));
System.out.println("spnego.getResponseCode():: "+spnego.getResponseCode());
if(spnego.getResponseCode() >= 200) {
log.debug("Authentication Successful");
}
文件读取/下载：
java.io.BufferedInputStream in = new java.io.BufferedInputStream( spnego.getInputStream());
java.io.FileOutputStream fos = new java.io.FileOutputStream(outputFile);
java.io.BufferedOutputStream bout = new BufferedOutputStream(fos,1024);
byte[] data = new byte[1024];
int x=0;
System.out.println("4" + outputFile.length());
while((x=in.read(data,0,1024))>=0) {
bout.write(data,0,x);
}
bout.close();
in.close();
您可以建议如何使用java代码将文件上传到Sharepoint文件夹。我搜索了很多论坛几个小时但没有获得文件上传的确切代码。您对此的建议非常感谢。
提前致谢。

经过10天的研究和搜索很多博客后，我找到了解决问题的方法。我希望这可以帮助有需要的人：
上传多个文件到SHAREPOINT（KERBEROS AUTHENTICated）：
System.setProperty("java.security.krb5.conf", workareaFolder+"/"+props.getProperty("kerberos.conf.file"));
System.setProperty( "java.security.auth.login.config", workareaFolder+"/"+props.getProperty("jass.conf.file"));
System.setProperty( "javax.security.auth.useSubjectCredsOnly", "false");
