package com.jeff.demo;import java.io.InputStream;import org.apache.commons.io.IOUtils;import com.alibaba.fastjson.JSONObject;public class FileDemo3 { public static JSONObject fileToJson(String fileName) { JSONObject json = null; try ( InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream(fileName); ) { json = JSONObject.parseObject(IOUtils.toString(is, "utf-8")); } catch (Exception e) { System.out.println(fileName + "文件读取异常" + e); } return json; } public static void main(String[] args) { String fileName = "doc/demo.json"; JSONObject json = FileDemo3.fileToJson(fileName); System.out.println(json); }} |
4、控制台输出结果
