Question

当我执行以下命令时：

ObjectMapper mapper = new ObjectMapper( new YAMLFactory() );
try {

  Map matchReport = mapper
      .readValue( new File( "C:\\temp\\test.yaml" ),Map.class );

  mapper.writeValue( System.out, matchReport );
}
catch ( Exception e ) {
  e.printStackTrace();
}
}

对于以下输入：

{
  "$id": "1",
  "$type": "LongoMatch.Core.Store.Project, LongoMatch.Core",
  "ID": "ae8a4461-b385-4b80-9a54-2254147820f8",
  "Periods": [
    {
      "$id": "106",
      "$type": "LongoMatch.Core.Store.Period, LongoMatch.Core",
      "ID": "4e1d0f3f-6dfb-40b0-b7f9-3743c661510d",
      "Name": "1",
      "Nodes": [
        {
          "$id": "107",
          "$type": "LongoMatch.Core.Store.TimeNode, LongoMatch.Core",
          "Name": "1",
          "Start": 0,
          "Stop": 1275931,
          "EventTime": 0,
          "Rate": 1.0
        }
      ],
      "Team": 0
    },
    {
      "$id": "108",
      "$type": "LongoMatch.Core.Store.Period, LongoMatch.Core",
      "ID": "79d8422e-0ff0-44bf-836d-cb2f4d41ea53",
      "Name": "2",
      "Nodes": [
        {
          "$id": "109",
          "$type": "LongoMatch.Core.Store.TimeNode, LongoMatch.Core",
          "Name": "2",
          "Start": 1275931,
          "Stop": 2551862,
          "EventTime": 1275931,
          "Rate": 1.0
        }
      ],
      "Team": 0
    }
  ],
  "Timers": [],
  "Playlists": []
}

我得到以下输出：

$id: "1"
$type: "LongoMatch.Core.Store.Project, LongoMatch.Core"
ID: "ae8a4461-b385-4b80-9a54-2254147820f8"

Timers: []
Playlists: []

是否存在并且可以强制写入[]和{}而不是-的选项？我尝试了CANONICAL_OUTPUT选项。但是随后我得到了[]和{}以及许多其他字符。编码回流后，是否存在和选项可以获得完全相同的结果？

使用Jackson不对称的Yaml编码/解码
