使用Java读取yaml文件-无法读取列表列表

Question

我正在使用Java读取yaml文件，并且在我的yaml文件中有ArrayList of Arraylists。

但是在读取文件时并没有获取文件的内容。

我得到的结果如下。

Persons 
    [persons=
        [
            [name, phone, address], 
            [name, phone, address], 
            [name, phone, address, favorite],
            [name, phone, address]
        ]
    ]

请找到我的yaml文件

persons:
 - name: Joe
   phone: 111-111-1111
   address: Park Dr, Charlie Hill

 - name: Trish
   phone: 111-111-11111
   address: Small Vine, River Town

 - name: Karthik
   phone: 111-222-2222
   address: Park Avenue
   favorite:
    - game1: Tennis
    - game2: FootBall
 - name: Anushka
   phone: 111-333-4444
   address: London
