HI All, We have a problem with UPPERCASE fields, like in this closed issued in Jackson
https://github.com/FasterXML/jackson-databind/issues/1609 But I prefer to know your opinion due to I think that it is really an issue. We have to integrate with an API that its swagger api model has all the fields with UPPERCASE , like the following definition: OutputTO: description: ... type: object properties: *UPPERCASEFIELD*: type: string description: .... example: ... In our case, using openapi generator plugin , the field in the class is created with the following sintax: @JsonProperty("UPPERCASE") private String UPPERCASE; public InputTO UPPERCASE(String UPPERCASE) { this.UPPERCASE = UPPERCASE; return this; } public String getUPPERCASE() { return UPPERCASE; } public void setUPPERCASE(String UPPERCASE) { this.UPPERCASE = UPPERCASE; } The problem appears when is parsed to json due to the field is duplicated: {"uppercase":"upperCase","CAMELCASE":"camelCase","UPPERCASE":"upperCase"} As you can see the field UPPERCASE is duplicated. I know that there are two possible workarounds to solve this kind of stuff: 1) Put the @JsonProperty on getter, but in that case is not possible due to we use openapi generator based on spring cloud, and its template only adds the annotation on field https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator/src/main/resources/JavaSpring/pojo.mustache 2) Reduce the visibility in ObjectMapper, to only explore Fields: ObjectMapper mapper = new ObjectMapper(); mapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY); mapper.setVisibility(PropertyAccessor.GETTER, Visibility.NONE); mapper.setVisibility(PropertyAccessor.SETTER, Visibility.NONE); But we would prefer not to use this workaround. So... Is it possible that in Jackson really exists a bug? I prefer to explore a solution in this forum first. -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
