<strong>Warning:</strong> this class represents null in two incompatible ways: the standard Javanullreference, and the sentinel valueJSONObject#NULL. In particular, callingput(name, null)removes the named entry from the object butput(name, JSONObject.NULL)stores an entry whose value isJSONObject...
1. JSON转为Java对象---readValue(了解,用得不多) 使用步骤 1). 导入jackson的相关jar包 2). 创建Jackson核心对象 ObjectMapper 3). 调用ObjectMapper的相关方法进行转换 readValue(json字符串数据,Class)(class为转成的对象的类型,如person.class) 2
