发生以太网失败：com.jcraft.jsch.JSchException：验证失败

Question

我尝试了下面的代码，但我一直得到例外情况如下， 请让我知道我在这里缺少的东西..提前致谢...

  

com.jcraft.jsch.JSchException：Auth失败               在com.jcraft.jsch.Session.connect（Session.java:473）               在com.jcraft.jsch.Session.connect（Session.java:145）               在FileCopierOverNetwork.main（FileCopierOverNetwork.java:34）

示例程序：
