如何从Java发送短信？

import com.qcloud.sms.SmsSingleSender;
import com.qcloud.sms.SmsSingleSenderResult;

public class SendSms {
    public static void main(String[] args) {
        // 应用ID和应用Key
        int appId = 123456789;
        String appKey = "1234567890abcdef1234567890abcdef";

        // 创建SmsSingleSender实例
        SmsSingleSender ssender = new SmsSingleSender(appId, appKey);

        // 设置短信内容和接收手机号码
        String[] phoneNumbers = {"1234567890"};
        String templateId = "1234";
        String[] params = {"123456", "5"};
        String sign = "腾讯云";

        // 发送短信
        try {
            SmsSingleSenderResult result = ssender.send(0, "86", phoneNumbers[0],
                templateId, params, sign);
            System.out.println(result);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
