Jersey/Jackson @JsonIgnore on setter

Question

i have an class with the following annotations:

class A {
public Map> references;

@JsonProperty
public Map

        

Answer 1

I think there are two key pieces that should enable you to have "read-only collections" as desired. First, in addition to ignoring the setter, ensure that your field is also marked with @JsonIgnore:

class A {

  @JsonIgnore
  public Map> references;

  @JsonProperty
  public Map> getReferences() { ... }

  @JsonIgnore
  public void setReferences(Map>) { ... }

}

Second, in order to prevent the getters from being used as setters, disable the USE_GETTERS_AS_SETTERS feature:

ObjectMapper mapper = new ObjectMapper();
mapper.disable(MapperFeature.USE_GETTERS_AS_SETTERS);
