解决：com.alibaba.fastjson.JSONException: parse number key errorpos 3, json

在解析JSON的时候，除了

代码:

public static void testMe() {Map map = new HashMap();map.put("1", "2");map.put("weq", "asd");map.put("qw", "");List list = new ArrayList();list.add(map);list.add(map);list.add(null);String str1 = String.valueOf(list);System.out.println(String.valueOf(list));List ss = JSON.parseObject(str1,List.class);}

报错信息：
