Question

您好我正在尝试使用简单的refular classm读取java中的url然后我得到一个字符串。我将该字符串存储在2个不同的变量中并打印该变量。当我打印该变量时，我在控制台上获得了一些印地语字体和英语。

当我尝试在我的jsp页面上使用相同的URL时，我只得到垃圾字符。我没有得到印地文字体。但是我想要在控制台上获得相同的输出。

这是我的

CommoditywiseGetUrl.java

public class CommoditywiseGetUrl {

    public static void main(String args[]) {
        URL url;
        try {
            // get URL content

            String a = "http://122.160.81.37:8080/mandic/commoditywise?c=paddy";
            url = new URL(a);
            URLConnection conn = url.openConnection();

            // open the stream and put it into BufferedReader
            BufferedReader br = new BufferedReader(
                    new InputStreamReader(conn.getInputStream()));

            StringBuffer sb = new StringBuffer();
            String inputLine;
            ArrayList<String> list1 = new ArrayList<String>();
            ArrayList<String> list2 = new ArrayList<String>();

            while ((inputLine = br.readLine()) != null) {

                String s = inputLine.replace("|", "\n");

                s = s.replace("~", " ");
                //System.out.println(s);
                StringTokenizer str = new StringTokenizer(s);
                while (str.hasMoreTokens()) {
                    String mandi = str.nextElement().toString();

                    String price = str.nextElement().toString();

                    //  System.out.println("Mandi:--->"+mandi);
                    //System.out.println("Price:--->"+price);
                    list1.add(mandi);
                    list2.add(price);
                }
            }
            String item1 = null;
            int i = 0;
            int j = 0;
            for (i = 0; i < list1.size() - 195; i++) {
                System.out.println(list1.get(i));

            }
            for (j = 0; j < list2.size() - 195; j++) {


                System.out.println(list2.get(j));

            }
            br.close();

            //System.out.println(sb);
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

它看起来像是一个字符编码问题。

您可以按照JSP中的规定将字符编码为UTF-8，如下所示

Charset.forName("UTF-8").encode(myString)
