Json反序列化Java

Question

我有一个简单的问题，假设我有这个json

{
   "outer-field":{
      "outer-a":"something",
      "outer-b":12345678,
      "inner-field":{
         "inner-a":false,
         "inner-b":0.0,
         "inner-c":29.99
      }
   }
}

以这种方式映射：

public class OuterObject {

    @JsonProperty("outer-a")
    public String outerA;
   
    @JsonProperty("outer-b")
    public Integer outerB;
   
    @JsonProperty("inner-field")
    public InnerObject innerField;

}

public class InnerObject{

    @JsonProperty("inner-a")
    public Boolean innerA;

    @JsonProperty("inner-b")
    public Double innerB;

    @JsonProperty("inner-c")
    public Double innerC;

我想知道是否可以通过使用一些自定义setter/注释或其他东西在内部对象中保存一个外部字段：

public class InnerObject{

    @JsonProperty("inner-a")
    public Boolean innerA;

    @JsonProperty("inner-b")
    public Double innerB;

    @JsonProperty("inner-c")
    public Double innerC;

    //how to map this?
    @JsonProperty("outer-a")
    public String outerA;

PS：由于json的复杂性，使用自定义反序列化是我最后的选择

Answer 1

You could do this 
Deserialization in the context of gson means converting a JSON string to an equivalent Java object.**
And you have to convert 


Gson gson = new GsonBuilder()
      .registerTypeAdapter(LocalDate.class, new LocalDateAdapter())
      .create();
      
YourPojoClassname objectname = gson.fromJson(jsonString, YourPojoClassname.class)

例如

您的pojo类名称并打印您的pojo类。
