Spring GlobalExceptionHandler : java.lang.IllegalStateException: Could not resolve parameter [0] ... No suitable resolver

Question

I had the following error when trying to setup a global exception handler to respond with a generic error response:

@RestControllerAdvice
class GlobalExceptionHandler {

    @ExceptionHandler(HttpClientErrorException::class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    fun handleClientException(exception: HttpClientErrorException): ErrorDto {
        // do something with client errors, like logging
        return ErrorDto(errorMessage)
    }

    @ExceptionHandler(Exception::class)
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    fun handleServerException(exception: HttpClientErrorException): ErrorDto {
        // do some other thing with server errors, like alerts
        return ErrorDto(errorMessage)
    }

}

data class ErrorDto(val message: String)

@RestController
class DemoController {
    @GetMapping("/error")
    @ResponseBody
    fun error(): ErrorDto {
        throw RuntimeException("test")
    }
}

and the error:

ExceptionHandlerExceptionResolver : Failure in @ExceptionHandler
public ErrorDto
GlobalExceptionHandler.handleServerException(org.springframework.web.client.HttpClientErrorException)

java.lang.IllegalStateException: Could not resolve parameter [0] in
public ErrorDto
GlobalExceptionHandler.handleServerException(org.springframework.web.client.HttpClientErrorException):

This is not a duplicate of spring mvc controller error java.lang.IllegalStateException: No suitable resolver for argument [0] which was an Hibernate issue. I am not using Hibernate here.

Answer 1

In my case, this was a copy-paste error.

I was throwing a RuntimeException but I configured the exception handler to support HttpClientErrorException :

fun handleServerException(exception: HttpClientErrorException)

In this case, the fix is to use the same Exception class in the @ExceptionHandler annotation as in the method parameter:

@ExceptionHandler(Exception::class) // <-- must match method parameter
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
fun handleServerException(exception: Exception): ErrorDto { // <-- fix here
    // do some other thing with server errors, like alerts
    return ErrorDto(errorMessage)
}
