在Java中实现免密连接可以使用公钥认证的方式,下面是一个简单的示例代码:
```java
import com.jcraft.jsch.*;
public class SSHConnection {
private String host;
private int port;
private String username;
private String privateKey;
public SSHConnection(String host, int port, String username, String privateKey) {
this.host = host;
this.port = port;
this.username = username;
this.privateKey = privateKey;
}
public void connect() throws JSchException {
JSch jsch = new JSch();
jsch.addIdentity(privateKey);
Session session = jsch.getSession(username, host, port);
session.setConfig("StrictHostKeyChecking", "no");
session.connect();
Channel channel = session.openChannel("shell");
channel.connect();
}
public static void main(String[] args) throws JSchException {
String host = "your_host";
int port = 22;
String username = "your_username";
String privateKey = "path/to/your/private/key";
SSHConnection connection = new SSHConnection(host, port, username, privateKey);
connection.connect();
}
}
```
在上面的示例中,`connect()`方法使用JSch库创建了一个SSH连接,并添加了私钥进行身份验证,这样就实现了免密连接。您需要将`your_host`、`your_username`和`path/to/your/private/key`替换为实际的主机地址、用户名和私钥路径。需要注意的是,私钥文件必须有正确的权限设置,否则连接可能会失败。
