英文:

Jackson deserializing json choosen fields

问题

以下是您要翻译的内容:

有可能只对选择的字段进行 JSON 反序列化吗?
例如:

{
    "Version": 1,
    "Key": "353301_PC",
    "Type": "PostalCode",
    "Rank": 500,
    "LocalizedName": "Kleosin",
    "EnglishName": "Kleosin",
    "PrimaryPostalCode": "16-001",
    "Region": {
      "ID": "EUR",
      "LocalizedName": "Europe",
      "EnglishName": "Europe"
    }

我只想要 LocalizedName 和 EnglishName。尝试过使用 objectMapper 但是出现了错误。

英文:

there is possibility to deserialize Json only choosen fields?
Eg:

{
    "Version": 1,
    "Key": "353301_PC",
    "Type": "PostalCode",
    "Rank": 500,
    "LocalizedName": "Kleosin",
    "EnglishName": "Kleosin",
    "PrimaryPostalCode": "16-001",
    "Region": {
      "ID": "EUR",
      "LocalizedName": "Europe",
      "EnglishName": "Europe"
    }

And i want only LocalizedName and EnglishName. Tried with objectMapper but getting errors.

在你的数据类中添加 JsonIgnoreProperties 注解:

@JsonIgnoreProperties(ignoreUnknown = true)
public class YourClass {

   private String LocalizedName;

   private String EnglishName;
   
   ...
}
英文:

Add JsonIgnoreProperties annotation to your data class

@JsonIgnoreProperties(ignoreUnknown = true)
public class YourClass {

   private String LocalizedName;

   private String EnglishName;
   
   ...
}

你可以在 Region 类的字段上添加 @JsonIgnore。

英文:

you can add @JsonIgnore to the fields inside the Region class
