package main;
import com.company.mingspider;
import org.dom4j.DocumentException;
import org.dom4j.Node;
import org.dom4j.io.SAXReader;
import org.jsoup.nodes.Document;
import org.jsoup.select.Elements;
import java.io.IOException;
import java.util.List;
public class Main {
    public static void main(String[] args) {
        String ReponseBody=null;
        mingspider mingspider= new mingspider();
        try {
            SAXReader saxReader = new SAXReader();
            Document document;
            ReponseBody =mingspider.getrequestdata("https://gongshang.mingluji.com/beijing/diqu/%E4%B8%9C%E5%9F%8E");
            System.out.println(ReponseBody);
            document = (Document) saxReader.read(ReponseBody);
            Elements list = document.select("/name");
        } catch (IOException e) {
            e.printStackTrace();
        } catch (DocumentException e) {
            e.printStackTrace();
        }
        // write your code here
 }
    public static String getType(Object test) {
        return test.getClass().getName().toString();
    }
}

Document document = saxReader.read(ReponseBody);

这里的ResponseBody 是字符串,为啥报错呢?求教,谢谢
