如何遍历JSONObject（Java json-simple）

Question

我正在使用json-simple。如果我有一个JSON，如：

[
    {"id":"1","name":"...","description":"...","dtStart":"2012-03-27 03:00:00","dtEnd":"2012-03-28 03:00:00","activities":""},
    {"id":"1","name":"...","description":"...","dtStart":"2012-03-27 03:00:00","dtEnd":"2012-03-28 03:00:00","activities":""},{"id":"1","name":"...","description":"...","dtStart":"2012-03-27 03:00:00","dtEnd":"2012-03-28 03:00:00","activities":""},
    {"id":"1","name":"...","description":"...","dtStart":"2012-03-27 03:00:00","dtEnd":"2012-03-28 03:00:00","activities":""}
]

我如何迭代它？

Answer 1

您展示的示例属于JSONArray，因为它位于[和]之间。 您应该像其他任何java Array一样遍历它。

Answer 2

这将创建一个包含3个地图的列表。

for (Object o : (List)parser.parse(json)){
    Map m = (Map)o;
    //handle map
}
