如何移除API JSON响应中的方括号[]？（已解决：该问题此前迭代已修复，系误分配）

Hey folks, let's clear this up right away!

The original task was to adjust an API response that returned JSON in this format:

{"authorities": [{"authority": "Employee"}]}

The goal was to remove the square brackets ([]) from the response, converting the array structure into a single object output.

The related code setup includes:

• A Spring MVC endpoint mapped to /autho that returns a ResponseEntity<GetAuthorityResponse>
• The usr.getAuthorities() method (from Spring Security) returns a Collection<GrantedAuthority>
• GetAuthorityResponse converts that collection to a Collection<CustomAuthority>, where CustomAuthority is an enum annotated with @JsonFormat(shape=JsonFormat.Shape.OBJECT)

• This issue has already been fixed in a previous iteration
• This task was assigned by mistake, no further development or adjustments are needed here.
