Java 在json字段snames上迭代

我必须在json文件的字段上迭代。我正在使用杰克逊图书馆。我的Json文件如下所示：

  {"type":"item","id":"Q1","labels":{"en":{"language":"en","value":"universe"},"fr":{"language":"fr","value":"Univers"},"la":{"language":"la","value":"universum"},"uz":{"language":"uz","value":"Olam"},"ru":{"language":"ru","value":"\u0432\u0441\u0435\u043b\u0435\u043d\u043d\u0430\u044f"},"pl":{"language":"pl","value":"wszech\u015bwiat"},"nb":{"language":"nb","value":"universet"},"eo":{"language":"eo","value":"universo"},"it":{"language":"it","value":"universo"},"es":{"language":"es","value":"universo"},"de":{"language":"de","value":"Universum"},"ca":{"language":"ca","value":"univers"},"en-gb":{"language":"en-gb","value":"universe"},"de-ch":{"language":"de-ch","value":"Universum"}"}]},"claims":{"P1036":[{"mainsnak":{"snaktype":"value","property":"P1036","datavalue":{"value":"113","type":"string"},"datatype":"string"},"

为了做到这一点，我尝试了以下代码：（解析器在“type”标记之后启动）

我得到以下命令：

FieldName is id
FieldName is labels
FieldName is labels
FieldName is en
FieldName is en
FieldName is language
FieldName is language
FieldName is value
FieldName is value

而我试图传达的顺序是：

FieldName is id
FieldName is labels
FieldName is Claims

---

如何执行此操作？

json字符串无效
