【java开发】通过SSHClient实现文件上传到Linux

续上文：

通过文件+小工具复制密码实现文件从windows上传到linux

【Java开发】通过

我想法很简单，在开发环境不健全的情况下（没有Jenkins做流水发布等），我能用自助的方法实现版本从windows发布到Linux服务器。

网上找到了参考代码：

片段代码如下：

引入依赖：

/groupIdartifactIdsshj//version/depency

片段代码：

;;/***@*/@DatapublicclassSshInfoItem{Stringhost;intport;StringuserName;Stringpassword;}

;;;;;;/***@*/publicclassSshClientUtil{publicstaticStringuploadFile(Stringhost,intport,StringuserName,Stringpassword,StringlocalFilePath,StringremoteDir){try(SSHClientssh=newSSHClient()){//如果是首次连接服务器或者确定服务器是可信的，//可以通过调整主机密钥验证策略来接受新的主机密钥。//例如，在使用sshj库（假设SSHClient来自sshj库）时，//可以使用PromiscuousVerifier（不推荐用于生产环境，仅用于测试或确认信任关系）。(newPromiscuousVerifier());(host,port);(userName,password);try(SFTPClientsftp=()){Filefile=newFile(localFilePath);((),remoteDir+"/"+());}return"ok";}catch(Exceptione){();}}publicstaticvoidmain(String[]args){SshInfoIteminfo=();Stringhost=();intport=();StringuserName=();Stringpassword=();StringlocalFilePath="C:\\Temps\\";StringremoteDir="/webapp/tmp";Stringresult=uploadFile(host,port,userName,password,localFilePath,remoteDir);(result);}}

输出效果：

就是：

问题根源当使用SSHClient时出现“Couldnotverifyecdsa-sha2-nistp256hostkeywithfingerprint”错误，表明在SSH连接过程中主机密钥验证失败。这可能是因为客户端首次连接到服务器，没有保存服务器的主机密钥指纹；或者服务器的主机密钥发生了变化，而客户端仍在使用旧的指纹进行验证；也可能是存在网络问题导致获取到的指纹不准确。

解决方案首次连接或确认服务器可信时如果是首次连接服务器或者确定服务器是可信的，可以通过调整主机密钥验证策略来接受新的主机密钥。例如，在使用sshj库（假设SSHClient来自sshj库）时，可以使用PromiscuousVerifier（不推荐用于生产环境，仅用于测试或确认信任关系）。

信任的主机，我选择了添加这行代码解决：

(newPromiscuousVerifier());

代码可以改成如下：

;;;;;;/***@*/publicclassSshClientUtil{publicstaticStringuploadFile(Stringhost,intport,StringuserName,Stringpassword,booleanhostKeyVerifierFlag,StringlocalFilePath,StringremoteDir){try(SSHClientssh=newSSHClient()){//如果是首次连接服务器或者确定服务器是可信的，//可以通过调整主机密钥验证策略来接受新的主机密钥。//例如，在使用sshj库（假设SSHClient来自sshj库）时，//可以使用PromiscuousVerifier（不推荐用于生产环境，仅用于测试或确认信任关系）。if(hostKeyVerifierFlag){(newPromiscuousVerifier());}(host,port);(userName,password);try(SFTPClientsftp=()){Filefile=newFile(localFilePath);((),remoteDir+"/"+());}return"ok";}catch(Exceptione){();}}publicstaticvoidmain(String[]args){SshInfoIteminfo=();Stringhost=();intport=();StringuserName=();Stringpassword=();booleanhostKeyVerifierFlag=(()!=().intValue()==1);StringlocalFilePath="C:\\Temps\\";StringremoteDir="/webapp/tmp";Stringresult=uploadFile(host,port,userName,password,hostKeyVerifierFlag,localFilePath,remoteDir);(result);}}
