I'm making a REST API and I would like to add at the class generation the Jackson annotation to ignore null fields, so I would like to add this annotation onfly for certain classes, not for the hole project.
I know that this could be acomplished by adding in application.properties the following line :
spring.jackson.default-property-inclusion=non_null
But this is for entire project.
I see that there are some ".mustache" files
- api.mustache
- apiController.mustache
I supose that I have to add some code in one of this one, or should I insert some code in application.yml ?
I'm also using Spring Boot with Swagger-codgen.
Thank you in advance and have a nice day!
Ok, after few hours of research I found that because I'm using Swagger-codegen I have to search in https://github.com/swagger-api/swagger-codegen for all answers regarding Swagger-Codegen. Here are all the templates and I found that I need to add to my project the following two files
The path where you can find the above files is
swagger-codegen/modules/swagger-codegen/src/main/resources/JavaSpring/
More than that, those files are simple templates to generate your Pojo classes, so you need to add the @JsonInclude(JsonInclude.Include.NON_NULL)
annotation in the pojo.mustache file, above the line with public class {{classname}} {{#parent}}extends {{{parent}}}{{/parent}}...
in order to be inserted when you generate pojo classes.
And done, build your project again! :)
