Question

I am creating an API by using spring boot. In this project, I used spring web, JPA, jstl and MySql as dependencies of the API. In this project, I have created a Controller,

Answer 1

You could customise the JSON representation of the entity in the Controller by using Spring's support for Jackson's JSONView.

https://spring.io/blog/2014/12/02/latest-jackson-integration-improvements-in-spring#json-views

    @JsonView(View.Summary.class)
    @GetMapping("/developers/{id}")
    public ImModel findByName(@PathVariable final int id){
        return TaskRepository.findById(id);
    }

Alternatively, you could handle at the repository level by using Spring Data's projection functionality:

https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#projections

    @GetMapping("/developers/{id}")
    public ImModelSummaryProjection findByName(@PathVariable final int id){
        return TaskRepository.someMethodReturningSummaryProjection(id);
    }
