需要把

client.connect(linuxIP); 修改为client.connect(linuxIP, new IgnoreHostKeyVerification());

public static String  getLinuxFileName(String linuxIP,String logDirectoryPath, String partFileName){
        String fileName = null;
        SshClient client=new SshClient();
       try{
           client.connect(linuxIP, new IgnoreHostKeyVerification());
           //设置用户名和密码
           PasswordAuthenticationClient pwd = new PasswordAuthenticationClient();
           pwd.setUsername("xxxxxx");
           pwd.setPassword("xxxxx");
           int result=client.authenticate(pwd);
           if(result==AuthenticationProtocolState.COMPLETE){//如果连接完成
             logger.info("登录结果："+result);

           }
       }catch(IOException e){
           e.printStackTrace();
       }
       return fileName;
}
