How to stop executing commands that take too long

[BadKid90s]

try {
         sshClient = new SSHClient();
         sshClient.addHostKeyVerifier(new PromiscuousVerifier());
         sshClient.connect(host, port); // 连接到远程主机
         sshClient.authPassword(username, password); // 使用密码进行身份验证
         sshClient.setTimeout(timeout);
         sshClient.setConnectTimeout(timeout);
     } catch (IOException e) {
         throw new RuntimeException(e);
     }

 try {

            Session.Command cmd = session.exec(cmdStr);

            // 获取标准输出
            String output = IOUtils.readFully(cmd.getInputStream()).toString();
            log.debug("execute command output: {}", output);

            // 获取错误输出
            String errorOutput = IOUtils.readFully(cmd.getErrorStream()).toString();
            if (errorOutput != null && !errorOutput.isEmpty()) {
                log.debug("execute command error output: {}", output);
                throw new CommandExecuteException(errorOutput);
            }

            cmd.join(this.timeout, TimeUnit.SECONDS);

            session.close();
            return output;

        } catch (IOException e) {
            throw new CommandExecuteException(e.getMessage());
        }

How to stop executing commands that take too long？？？

 sshClient.setTimeout(timeout);   
 sshClient.setConnectTimeout(timeout);    
 cmd.join(this.timeout, TimeUnit.SECONDS);  

None of them have taken effect
