mysql-java解析 新浪微博Json数据,获取uid和text
mysql数据挖掘javajson
json格式如下:
{"reposts_count": 0, "mlevel": 0, "user_id": 1620302927, "retweeted_status": {"reposts_count": 1, "user_id": 2209251457, "text": "\u4e24\u6735\u5c0f\u83ca\u82b1\u554a,\u5f00\u5728\u82b1\u4e1b\u4e2d\u554a"}
数量有很多,是以txt文本存在D盘,现在的流程是这样:读取文本->解析Json,获得uid和text(将utf-8编码改为中文)->存入MySql数据库的retweetedWeibo表里,只有2个字段(uid,text)。
已经在网上找过很多java 解析json的代码,但有错,而且很乱,有的用的jar包,有的又不写清楚,搞的我要抓狂了简直。 要是大神们解决了我的问题,再加C币!
为什么大家都只看到了解析json,其他的呢?上面还写了其他的要求啊?而且,你们的解析Json代码我在网上都有看到过,有的还试过了。我其实想要的是完整版的代码。辛苦大家了。
