如何在属性中使用Lombok定义JSON：@JsonPropertyOrder和@JsonIgnore（JAVA）

Question

I'm trying to use lombok with JSON but I have some hiccups

Json is not respecting the order when the name of the variable is different from @JsonProperty.

(it's probably a problem with the getters)

Another point is that I would like to hide the id of the Object1 in the generated json

@Data
@Builder(toBuilder = true)
@AllArgsConstructor(access = AccessLevel.PACKAGE)
@NoArgsConstructor(access = AccessLevel.PACKAGE)
@JsonPropertyOrder({ "id", "objectid", "value" })
public class Object1 {

@JsonIgnore
private Long id;

@JsonProperty("objectid")
private Long subid;

@JsonProperty("value")
private String value;

}

Result:

{
  "id" : 123,  <--- I want to hide
  "value" : "...",
  "objectid" : 123
}

"this is a small and fictional class"

Thanks,

Answer 1

To solve the output order try to use ObjectMapper like this:

ObjectMapper om = new ObjectMapper();
String jsonString = om.writeValueAsString(myObject1);
System.out.println(jsonString);

To hide the id you can use this jackson annotation:

@JsonIgnoreProperties(value = {"id"})

If you still want to be able to set the id using setter add this member to the annotation:

allowSetters = true

Your code works fine... What do you want to get in result?
