在Java中,可以使用JSch库来连接SFTP服务器。以下是连接SFTP服务器的基本步骤:
1. 导入JSch库
```java
import com.jcraft.jsch.*;
```
2. 创建JSch对象
```java
JSch jsch = new JSch();
```
3. 创建Session对象
```java
String host = "sftp.example.com";
String username = "username";
int port = 22;
Session session = jsch.getSession(username, host, port);
```
4. 设置Session属性
```java
// 设置密码
String password = "password";
session.setPassword(password);
// 设置StrictHostKeyChecking属性为no,跳过公钥的检查
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
// 设置超时时间
session.setTimeout(10000);
```
5. 连接Session
```java
session.connect();
```
6. 创建Channel对象
```java
Channel channel = session.openChannel("sftp");
```
7. 连接Channel
```java
channel.connect();
```
8. 使用Channel进行SFTP操作
```java
ChannelSftp sftpChannel = (ChannelSftp) channel;
// 下载文件
String remoteFilePath = "/remote/file/path";
String localFilePath = "/local/file/path";
sftpChannel.get(remoteFilePath, localFilePath);
// 上传文件
sftpChannel.put(localFilePath, remoteFilePath);
// 列出远程目录下的文件
Vector<ChannelSftp.LsEntry> files = sftpChannel.ls("/remote/directory/path");
for (ChannelSftp.LsEntry file : files) {
System.out.println(file.getFilename());
}
// 删除远程文件
sftpChannel.rm("/remote/file/path");
```
