我有一个复杂的JSON写在一个字符串。我知道java和一点mysql。我需要从json中创建一个数据库。如何解析json到数据库?
我正在使用一些Twitter数据,因此推文包含推文推文的用户的描述,并且在推特被转推的情况下,它包含推介此用户之前用户的描述。
我的目标是创建一个用户表(或数组或任何其他数据结构),其中包含此用户发送的所有推文以及所有推文转发的推文。
tweet对象包含大约50-80个对象,所以在这里给出一个例子将使这篇文章真的很长。

给出至少一个提取物! – fge 2011-12-18 11:25:22
这实际上是2个问题之一 - 如何解析JSON以及如何在数据库中保存数据。哪一部分很难? – extraneon 2011-12-18 11:35:36
增加了一个例子。 – R1234 2011-12-18 11:38:34
