java连接linux

1.在java代码中连接linux服务器

 1.1依赖的添加

<dependency><groupId>commons-net</groupId><artifactId>commons-net</artifactId><version>2.2</version></dependency><dependency><groupId>com.jcraft</groupId><artifactId>jsch</artifactId><version>0.1.54</version></dependency><dependency>  <groupId>ch.ethz.ganymed</groupId>  <artifactId>ganymed-ssh2</artifactId>  <version>build210</version></dependency>

1.2java代码示例
