com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException：無法識別的字段“ g”

Question

有人可以用下面的java pojo做些什么。 我越來越例外

    {
      "epoch": 1407877412466,
      "ids": {
        "DUMMY1": "abcd",
        "DUMMY2": "pqrs"
      },
      "vf": {
        "ANS1": {
          "g": 0
        },
        "ANS2": {
          "g": 0
        },[...]
      }
    }

例外

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException：無法識別的字段“ g”（com.adtruth.zander.persistence.domain.VfdData類），未標記為可忽略（4個已知屬性：“ query”，“ vf”，“ ids“，” epoch“]）在com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException.from（UnrecognizedPropertyException.java:51）在com.fasterxml.jackson.databind.DeserializationContext.reportUnknownProperty（DeserializationContext.java:731） .fasterxml.jackson.databind.deser.std.StdDeserializer.handleUnknownProperty（StdDeserializer.java:915）位於com.fasterxml.jackson.databind.deser.BeanDeserializerBase.handleUnknownProperty（BeanDeserializerBase.java:1298）

Answer 1

Scores類應該是靜態的（或是頂級類）。
