對(duì)List和map等結(jié)構(gòu)的常用轉(zhuǎn)換操作基本上可以滿足我們處理的絕大多數(shù)需求,但有時(shí)項(xiàng)目中對(duì)json有特殊的格式規(guī)定.比如下面的json串解析:
[{"tableName":"students","tableData":[{"id":1,"name":"李坤","birthDay":"Jun 22, 2012 9:54:49 PM"},{"id":2,"name":"曹貴生","birthDay":"Jun 22, 2012 9:54:49 PM"},{"id":3,"name":"柳波","birthDay":"Jun 22, 2012 9:54:49 PM"}]},{"tableName":"teachers","tableData":[{"id":1,"name":"米老師","title":"教授"},{"id":2,"name":"丁老師","title":"講師"}]}]
分析之后我們發(fā)現(xiàn)普通的方式都不好處理上面的json串.請(qǐng)看本文是如何處理的吧:
