将 JSON 转换为 YAML.将 JSON 解析为 YAML

2022-01-14 00:00:00 json parsing yaml java

我正在处理配置文件，因此我需要将 JSON 转换为 YAML.例如我有这个 JSON 文件:

I'm working with configuration files so I need to convert JSON to YAML. For example I have this JSON file:

{
  "foo": "bar",
  "baz": [ "qux","quxx"],
  "corge": null,
  "grault": 1,
  "garply": true,
  "waldo": "false",
  "fred": "undefined",
  "emptyArray": [],
  "emptyObject": {},
  "emptyString": ""
}

结果应该是 YAML:

The result should be YAML:

foo: "bar"
baz: 
  - "qux"
  - "quxx"
corge: null
grault: 1
garply: true
waldo: "false"
fred: "undefined"
emptyArray: []
emptyObject: {}
emptyString: ""

你能帮帮我吗?

推荐答案

如果您需要将 JSONobject 转换为 yaml(字符串).你需要.首先获取json字符串，然后map，之后就可以转换成yaml了.代码如下:

If you need convert JSONobject to yaml (string). you need. Firstly get json string, then map, after that you can convert to yaml. Here the code:

  // this is your json object
  JSONObject jsonobject = new JSONObject(map);
  // get json string
  String prettyJSONString = jsonobject.toString(4);
  // mapping
  Map<String,Object> map = (Map<String, Object>) yaml.load(prettyJSONString);
  // convert to yaml string (yaml formatted string)
  String output = yaml.dump(map2);
