有一个机器人可以从网站上拍摄顶级电影图片并将其发送到聊天室。问题在于它仅在您输入任何消息时才发送它们，并且通过一遍又一遍地发送消息，机器人从头开始相应地开始发送消息。我试图将发送发送到一个单独的线程中，但是没有用（也许我做错了）。总体而言，我需要该机器人每30分钟发送一次阵列中的照片图像。
负责创建图像链接数组的类：
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
public class NewFilms {
private static ArrayList<String> absoluteUrls = new ArrayList<>();
public NewFilms() throws IOException {
createArrayOfImages();
}
private static void createArrayOfImages() throws IOException {
Document document = Jsoup.connect("http://gidonline.in/").get();
List<Element> imageElements = document.select("img[src$=120x170.jpg]");
for (Element element : imageElements) {
absoluteUrls.add(element.absUrl("src"));
}
}
public static ArrayList<String> getAbsoluteUrls() {
return absoluteUrls;
}
}
