要使用ProcessBuilder调用远程Python脚本,你需要将Python脚本上传到远程服务器,并使用SSH协议连接到远程服务器。然后,你可以使用ProcessBuilder来启动SSH客户端并执行远程Python脚本。下面是一个示例代码:
```
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class RemotePythonCaller {
public static void main(String[] args) {
String remoteHost = "your-remote-host";
String remoteUser = "your-remote-user";
String remotePassword = "your-remote-password";
String remoteFilePath = "path-to-your-remote-python-script.py";
String command = String.format("sshpass -p %s ssh %s@%s python %s", remotePassword, remoteUser, remoteHost, remoteFilePath);
try {
ProcessBuilder processBuilder = new ProcessBuilder(command.split(" "));
Process process = processBuilder.start();
BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
int exitCode = process.waitFor();
System.out.println("\nExited with error code : " + exitCode);
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
在这个示例代码中,我们使用了sshpass工具来在Java代码中提供远程服务器的密码。请注意,这种方法并不安全,因为密码可能会被泄露。因此,建议使用SSH密钥身份验证来代替密码身份验证。
