[Fixed] Facing Issue With HttpStatus in spring boot 3

Quick Fix: To resolve the issue in Spring Boot 3, modify the code to return an HttpStatusCode object instead of a numeric status code. For example, replace:

return 204;

with:

return HttpStatusCode.valueOf(HttpStatus.NO_CONTENT.value());

The Problem:

When upgrading a Spring Boot project to use Spring 6.x, a developer encounters an issue with the HttpStatus class. The HttpStatus class is deprecated in Spring 6.x, and the code that previously returned HttpStatus.NO_CONTENT and HttpStatus.INTERNAL_SERVER_ERROR now causes compile-time errors due to incompatible types.

The Solutions:

Solution 1:

Replace the use of HttpStatus with HttpStatusCode. HttpStatus is deprecated in Spring 6.x and has been replaced by HttpStatusCode. To handle the issue of incompatible types, explicitly convert the desired HttpStatus value to HttpStatusCode using the valueOf() method. For instance:

ResponseEntity.ok().status(HttpStatusCode.valueOf(HttpStatus.NO_CONTENT.value()));
