从远程服务器上拷贝文件到本机: SCPClient 使用简单记录

 一、依赖

<dependency>
    <groupId>ch.ethz.ganymed</groupId>
    <artifactId>ganymed-ssh2</artifactId>
    <version>262</version>
</dependency>

 二、逻辑实现

import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.SCPClient;
import ch.ethz.ssh2.SCPInputStream;

import java.io.File;
import java.io.FileOutputStream;

            SCPClient sc = conn.createSCPClient();
            // 获取远程机器上的文件流 (远程文件地址的绝对路径)

        } catch (Exception e) {

        }
    }
}
