Everything is pretty straightforward except for the "product_details" section, which contains a list of several JSON objects with different pieces of data each. Unfortunately, the tools available in Data Factory, like Flatten and Select, only recognize the first object in the "product...

在开发中,经常需要根据条件过滤大批量的JSON类型数据。如果仅需要过滤这一种类型,将JSON转为List后过滤即可;如果相同的条件既想过滤数据库表中的数据、也想过滤内存中JSON数据,甚至想过滤Elasticsearch中的数据,那可使用本博客中的方案,使用标准的SQL语法实现多种数据源中的查询或聚合操作。
QJson is a qt-based library that maps JSON data to QVariant objects. JSON arrays will be mapped to QVariantList instances, while JSON's objects will be mapped to QVariantMap. QJson requires: Qt 4.5 or greater cmake 2.6 or greater 使用过一段时间现实比较复杂,需要符合QVariant中对Meta Obj...
Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of. 1. 官...

Providing this typesafe view dynamically may cause a program fail with a ClassCastException, if there is a value of wrong type in this array. Unfortunately, the exception can occur at any time after this method returns. Parameters: clazz - a JsonValue type Returns: a list view of the ...
