ControllerAdvice 的异常处理程序在使用 Spring Boot 的 Rest API 获取请求中不起作用。 如何解决？

Question

I have a Rest Controller using Spring Boot

@RestController
@RequestMapping("/api")
public class TeamController {

@RequestMapping(value = "/getmember/{memberId}",method = {RequestMethod.GET})
    public ResponseEntity<TeamMember> findmember(@PathVariable("memberId") int theId){
        
        TeamMember teamMember = teamService.findMember(theId);
        if( null == teamMember) {
            throw new TeamMemberNotFoundException();
        }
        return new ResponseEntity<TeamMember>(teamMember,HttpStatus.OK);
        
    }

My Exception Class

@ResponseStatus(value = HttpStatus.NOT_FOUND, reason = "Member not found")
public class TeamMemberNotFoundException extends RuntimeException {

// constructor

}

My Global Exception Handler annotated using @ControllerAdvice

@ControllerAdvice
public class TeamMemberNotFoundExceptionHandler extends ResponseEntityExceptionHandler {
    
    
    @ExceptionHandler(TeamMemberNotFoundException.class)
    public ResponseEntity<TeamMemberNotFoundErrorResponse> handleException(TeamMemberNotFoundException e) {

        TeamMemberNotFoundErrorResponse t = new TeamMemberNotFoundErrorResponse(HttpStatus.NOT_FOUND.value(),"Dude he doesnt exist wake up",System.currentTimeMillis());
        
        return new ResponseEntity<TeamMemberNotFoundErrorResponse>(t, HttpStatus.NOT_FOUND);

    }
     
    
}

When Im using the Exception Handler code inside the controller directly it seems to work but the Exception Handler when used in the Class annotated with @Controller Advice is not called at all and I get default 500 Internal Server error. I have attached picture of my project directory structure. Im trying hard but unable to resolve this

This may happen because spring uses convention over configuration if you don't specify. One of the packages spring checks is the "exception" package, try putting your ControllerAdvice there. If it doesn't work, try specifying the package of your ControlerAdvice in your Application class.
