SomeObj:
type: object
properties:
$_type:
type: string
id:
type: integer
format: int64
name:
type: stringIt generates:
public class SomeObj {
@JsonProperty("$_type")
private String $type;
//...
public SomeObj $type(String $type) {
this.$type = $type;
return this;
}
/**
* Get $type
* @return $type
**/
@javax.annotation.Nullable
@ApiModelProperty(value = "")
public String get$Type() {
return $type;
}
public void set$Type(String $type) {
this.$type = $type;
}
//...
}Because the getter get$Type() looks a little bit different than the $type field annotated with @JsonProperty("$_type"), jackson serializes the object like this:
{ "$_type": "someValue", "$Type": "someValue", "id": 42, "name": "test"}Because all fields are generated with a proper @JsonProperty, discovery of the getters should be disabled when doing the serialization.
This can be configured in the generated JSON class:
|
public JSON() { |
|
mapper = new ObjectMapper(); |
|
mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL); |
|
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false); |
|
mapper.configure(DeserializationFeature.FAIL_ON_INVALID_SUBTYPE, false); |
|
mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS); |
|
mapper.enable(SerializationFeature.WRITE_ENUMS_USING_TO_STRING); |
|
mapper.enable(DeserializationFeature.READ_ENUMS_USING_TO_STRING); |
|
mapper.setDateFormat(new RFC3339DateFormat()); |
|
ThreeTenModule module = new ThreeTenModule(); |
|
module.addDeserializer(Instant.class, CustomInstantDeserializer.INSTANT); |
|
module.addDeserializer(OffsetDateTime.class, CustomInstantDeserializer.OFFSET_DATE_TIME); |
|
module.addDeserializer(ZonedDateTime.class, CustomInstantDeserializer.ZONED_DATE_TIME); |
|
mapper.registerModule(module); |
|
} |
By adding a disable command for:
- MapperFeature.AUTO_DETECT_CREATORS
- MapperFeature.AUTO_DETECT_FIELDS
- MapperFeature.AUTO_DETECT_GETTERS
- MapperFeature.AUTO_DETECT_IS_GETTERS
