我們需要將json資料歸納格式：
1、按照dataType，分類file，mysql。
2、按照pkValue分類。
3、按照eventType型別分類。
先來看第一個要求 ：按照dataType 分類file，mysql。直接getString(“dataType”)完事
再來看第二個要求：需要按照pkValue分類
這裡我使用的是alibaba的很強大的Json解析工具 pom 配置如下
<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.36</version> </dependency>

第三個要求其實和第二個是一樣的，都是通過每個子json串獲取key
如果還有別的需求 比如獲得每個子Json串的裡面的子Json串某個型別，像按照 “sqlType” , “pk” ，"value"等型別進行分類 就只需寫一個雙重迴圈就可以搞定
