POJO类的JSON字段名称

Question

I have a simple Java class:

class Feed { 
private String fieldOne;
private String fieldTwo;
}

and a JSON connected with this class:

{
  "feed": {
    "field_one": "1.780",
    "field_two": "1.810"
}

but when I send this json to server, all class fields are null. If i change fields name in JSON to fieldOne and fieldTwo it works fine. But is it possible to read this json without doing any changes in fields name in JSON or class?

Answer 1

You should do this :

class Feed { 
@XmlElement(name="field_one")
private String fieldOne;

@XmlElement(name="field_two")
private String fieldTwo;
}
