如何设置处理程序以将具有多种命名 styles 的 JSON 字段绑定到 POJO

Question

I'm using Springboot 2.5.1, Jackson 2.13.1

Input JSON looks like:

{
  "hello_word": "you are welcome",
  "my-name": "Meow",
  "Age": 11
}

Java POJO:

@Data
class A {

  private String helloWorld;

  private String myName;

  private Integer age;
}

Expected binding result:

class A {

  private String helloWorld = "you are welcome";

  private String myName = "Meow";

  private Integer age = 11;
}

As you can see, there are 3 naming styles in the JSON. I want to ask is there any way to set a handler or a subclass that can bind values correctly to POJO's fields in this case.

Answer 1

You can use @JsonProperty , for more examples

@Data
class A {

   @JsonProperty("hello_word")
   private String helloWorld;

   @JsonProperty("my-name")
   private String myName;

   @JsonProperty("Age")
   private Integer age;
}
