JSON快速取值（JAVA）
因为工作需要，经常要从复杂的json里面取值，每次要做写一堆JSONObject，然后我就写了一个小工具（刚毕业，写的很菜）。
工具代码
用了hutool的格式转换（Convert）、正则工具（ReUtil）和JSON工具
import cn.hutool.core.convert.Convert;import cn.hutool.core.util.ReUtil;import cn.hutool.json.*;import org.junit.Test;import java.util.ArrayDeque;import java.util.Arrays;import java.util.List;import

JSONTokener(jsonStr,JSONConfig.create()); Object json = jsonTokener.nextValue(); //获取头部属性 String poll = queue.poll(); // 判断json类型 if (json instanceof JSONArray) { JSONArray jsonArray = (JSONArray) json; List all = ReUtil.findAll("\[(\d+)\]", poll, 1); if (all.size() > 0) { //如果是数组 String index = all.get(0); // 判断当前队列是否有值 有就递归没有就返回jsonString String str = jsonArray.getStr(Convert.toInt(index)); if (queue.peek() != null) { return getValue(queue, str); } else { return str; } } return null; } else { JSONObject jsonObject = (JSONObject) json; List all = ReUtil.findAll("\[(\d+)\]", poll, 1); if
