Example value for some methods is not presented properly in 2.4.0

[avicentic]

Describe the bug

• In version 2.4.0 on some POST methods Example value is not presented as a structured json file with initial values. In version 2.3.0 everything works well.

To Reproduce
Steps to reproduce the behavior:

• Spring-boot version 3.2.3
• springdoc-openapi version 2.4.0
• Unfortunately, I cannot reproduce issue in a small demo project. It appears in production project that I cannot share.

More details

• Function in Rest controller is:
  @PostMapping(value = "/authenticate") public ResponseEntity<AuthenticateResponse> authenticate(HttpServletRequest request, @RequestBody AuthenticateRequest authenticateRequest) { AuthenticateResponse authenticateResponse = authService.authenticate(authenticateRequest, httpRequestUtil.getClientIP(request)); return new ResponseEntity<>(authenticateResponse, HttpStatus.OK); }
• AuthenticateRequest object is:
  @Getter @Setter @NoArgsConstructor @AllArgsConstructor @Builder public class AuthenticateRequest { private String ou; private String username; private String password; private TokenGrantType grantType; private String refreshToken; }
  On swagger page schema for request body is presented properly:
  
  but example value is dummy "string":
  

With springdoc-openapi version 2.3.0 example value is presented as a valid json object:

Surprisingly, I have same issue with all rest methods within one controller file. Methods from another controller files has valid examples for request body's.

Just noticed the same bug, all POSTs are affected. PUT, PATCH and GET are fine.

I noticed this issue as well.

Additional info:

• Service with many controllers/endpoints cannot show POST request body schema
• Service with few controllers is able to show schemas.

The api-docs JSON is semantically the same.

Not sure if this is related to #2538. I cannot override library version as said.

@stalinone,

Try using The latest SNAPSHOT where the swagger-ui has been upgraded.

@bnasslahsen I could confirm that bug is fixed in snapshot version.
