从java中的URL读取json的最简单方法

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;

public class ReadJsonFromURL {
    public static void main(String[] args) {
        try {
            URL url = new URL("https://example.com/jsonfile.json");
            BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream()));
            StringBuilder jsonContent = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                jsonContent.append(line);
            }
            reader.close();
            
            // 在这里可以对读取到的JSON内容进行处理
            System.out.println(jsonContent.toString());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
