java - JSch异常: No Configuration was registered named com. sun.security.jgss.krb5.initiate

Question

我正在运行此代码，但出现异常。

Session session = null;  
Channel channel = null;  

JSch jsch = new JSch();  
session = jsch.getSession(ftpUserName, ftpHost, ftpPort);  
if (session == null) {  
    throw new Exception("session is null");  
}  
session.setPassword(ftpPassword);  
session.setTimeout(100000);  
session.setConfig("StrictHostKeyChecking", "no");  
session.connect();  

该代码在本地开发环境中运行正常。但是在测试环境部署时报异常。测试环境为linux环境，部署中间件为weblogic11，使用的jdk均为oracle 1.6.45。

Answer 1

正如 @Chris 已经回答的，JSch 默认尝试 Kerberos/GSSAPI 身份验证。

由于您似乎不希望这样，请从默认的 JSch 身份验证方法列表 (gssapi-with-mic,publickey) 中删除 Kerberos/GSSAPI (gssapi-with-mic) ，键盘交互，密码):

session.setConfig("PreferredAuthentications", "publickey,keyboard-interactive,password");
