Jsch是一个Java库,用于SSH(Secure Shell)连接,包括SCP(Secure Copy)和SFTP(Secure File Transfer Protocol)。如果你想使用JSch从Java应用程序通过FTP上传文件,可以按照以下步骤操作:
1. **添加依赖**:首先需要在你的项目中引入JSch库。如果你使用Maven,可以在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>com.jcraft</groupId>
<artifactId>jssha</artifactId>
<version>0.18.0</version>
</dependency>
```
2. **初始化会话**:
```java
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
Session session = JSch.getSession("username", "hostname", port);
session.setPassword(password); // 设置用户名、主机名和密码
session.setConfig("StrictHostKeyChecking", "no"); // 可选设置,关闭HostKey检查
session.connect();
```
3. **打开SFTP通道**:
```java
ChannelSftp channel = (ChannelSftp) session.openChannel("sftp");
channel.connect();
```
4. **上传文件**:
```java
File localFile = new File("/path/to/local/file.txt");
String remoteFilePath = "/remote/directory/file.txt";
channel.put(localFile.getAbsolutePath(), remoteFilePath);
```
5. **关闭通道并断开连接**:
```java
channel.disconnect();
session.disconnect();
```
