遇到异常
java.lang.IllegalArgumentException: No Configuration was registered that can handle the configuration named com.sun.security.jgss.krb5.initiate
于2017/10/17遇上一个很脑残的异常,首先ping 和telnet都正常,其它系统使用一样的代码也正常能使用sftp功能,最终换了4个jsch-0.1.XX.jar才正常.
解决方法: 把jsch-0.1.42.jar替换成jsch-0.1.31.jar,没错,就是jar包问题,这个错报得真TMXX,偿试了千百种方法才误打误撞改好了.
