本文提供了解决Java代码尝试连接Linux服务器时遇到‘Keyexchangewasnotfinished’错误的步骤，包括在sshd_config中更新KexAlgorithms列表并重启sshd服务。

       java代码连接Linux服务器时，报错“There was a problem while connecting to XX.XX.XX.XX

Caused by: java.io.IOException: Key exchange was not finished, connection is closed.”的解决方案。

【解决方案】

（1）在/etc/ssh/sshd_config文件最后一行加上（文字不换行）：

KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group1-sha1,curve25519-sha256@libssh.org

（2）重启sshd服务

systemctl restart sshd.service

我们项目需要通过SFTP对接大量上下游获取数据，但是由于某一个上游需要更换作为他们的SFTP服务，他们的SFTP服务使用更高版本的OpenSSH服务，原有的一些密钥算法已经不再支持，我们目前使用的Jcraft公司发布的Jsch版本已经没办法满足，需要进行升级。但是Jcraft公司的Jsch0.1.55版本从2018年开始就停止维护，我们不得不升级到另一个mwiede继续维护的Jsch版本(基于原有0.1.55fork的分支)以满足更多算法的需要。
