要在Java中实现SSH密钥链接,您可以使用JSch库。以下是一个简单的示例代码,它使用JSch连接到远程主机并执行命令:
```java
import com.jcraft.jsch.*;
public class SSHExample {
public static void main(String[] args) {
String user = "your_username";
String host = "your_remote_host";
int port = 22;
String privateKey = "/path/to/your/private_key";
try {
JSch jsch = new JSch();
jsch.addIdentity(privateKey);
Session session = jsch.getSession(user, host, port);
session.setConfig("StrictHostKeyChecking", "no");
session.connect();
Channel channel = session.openChannel("exec");
((ChannelExec) channel).setCommand("ls -l");
channel.setInputStream(null);
((ChannelExec) channel).setErrStream(System.err);
InputStream in = channel.getInputStream();
channel.connect();
byte[] tmp = new byte[1024];
while (true) {
while (in.available() > 0) {
int i = in.read(tmp, 0, 1024);
if (i < 0) break;
System.out.print(new String(tmp, 0, i));
}
if (channel.isClosed()) {
if (in.available() > 0) continue;
System.out.println("exit-status: " + channel.getExitStatus());
break;
}
try {
Thread.sleep(1000);
} catch (Exception ee) {
}
}
channel.disconnect();
session.disconnect();
} catch (JSchException | IOException e) {
e.printStackTrace();
}
}
}
```
在上面的示例代码中,您需要将`your_username`,`your_remote_host`和`/path/to/your/private_key`替换为实际的值。此外,您还可以更改执行的命令,以便执行任何命令。
