good one, but how can we access our request body in the rest controller advice. I want some operation on it and merge it in the error response. Thanks :)
Thank You sir for your valuable lectures and guidelines . By following the guidelines I am able to know the spring boot api concepts. Unfortunately, I am facing a problem in database when ever I change any portion in my code the Id of the database value changed by default 50 gave not in sequential like-1,2,3. Even I deleted the id sequence is still same as before. How can I generated the id sequential even the id is deleted. If you know me that will be very efficient for me.

sir, when we created User entity we annotated the fields with @Column(nullable=false)...why is hibernate letting null values be inserted in database...why do we need to validate again the Dto objects?

its happening only with this project in other projects from other videos its not entering null entries

Make Course On Java/Jakarta Enterprise Edition
Please make the frontend with angular.

Please let us know how we fixed this issue
I am using @pattern and have to fetch regex and message from properties file how it can be implemented?
Hey did you create this project can you help me ?
@@kumarisneha9392 ok
Why we didn't create a class for MethodArgumentNotValidException like in the case of ResourceNotFound Exception?
because MethodArgumentNotValidException class is already defined in java. ResourceNotFound class was defined by us it is not built inside java

@paul it got resolved i missed creating method for validation in global exception
@@adityashrivastava1915 it doesnt matter whether you create the exception catching method in global exception handlers or not...Postman should show the generated exception thrown in json format anyways

Question: how to validate if path variable is coming valid or not...I gave @ valid and @notnull infront of @pathvariable but it was not working .
Can u please help
you need to annotate your controller class with @Validated annotation.
@@ghostcoderz I have given @validated still not working...if I give @nullnot then it's still not giving any error if I give path variable values as null ,not sure y
1- add @Validated in controller,
2- add annotation for validation after @pathvariable.
@RestController
@RequestMapping("/api/users")
@Validated
public class UserController {
@Autowired
private UserService userService;
@GetMapping("/{userId}")
public ResponseEntity getUser(@PathVariable @Range(min=1,max=100,message="id must be between 1 to 100") Integer userId)
{
UserDto user=this.userService.getUserById(userId);
return new ResponseEntity(user,HttpStatus.OK);
}
}
//If you enter id 101,you will get ConstraintViolationException
'//add this method in GlobalExceptionHandler for proper handling
@ExceptionHandler(ConstraintViolationException.class)
public ResponseEntity constraintViolation(ConstraintViolationException ex){
return new ResponseEntity(ex.getMessage(),HttpStatus.BAD_REQUEST);
}
@@sunil3382 thanks it's working now
