class Apple{

@JsonProperty("colour")
public String colour;

@JsonProperty("dummy_params")
public DummyParams dummyParams;

}

public abstract class AppleMixin{

    @JsonIgnore
    @JsonProperty("dummy_params")
    public DummyParams dummyParams;

}

我试图在使用objectmapper时忽略dummyparams字段

class Tester{
  public static void main(){
  Apple app = new Apple();
  app.setColor("red");
  app.setDummyParams(new DummyParams("1","2"));

  ObjectMapper objecMapper = new ObjectMapper();
  objecMapper.addMixIn(Apple.class, AppleMixin.class);
  String result = objecMapper.writeValueAsString(exec);
  }
}

我正在使用com.fasterxml.jackson.databind.objectmapper
预期结果：{“colour”：“red”}
实际结果：{“colour”：“red”，“dummyparams”：{“dummyone”：1，“dummytwo”：2}}
混音器坏了。我做错了吗？
