If a client sends a request with parameter not matching the endpoints parameter type,there will throw TypeMismatchException .

@RestController
public class DemoController {

    @GetMapping("/test")
    public String demo(Long id) {

        return "success";
    }

clients send requests to the "/test?id=undefined" .

error logs :

org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.lang.Long'; nested exception is java.lang.NumberFormatException: For input string: "undefined"
    at org.springframework.web.method.annotation.AbstractNamedValueMethodArgumentResolver.resolveArgument(AbstractNamedValueMethodArgumentResolver.java:133) ~[spring-web-5.2.8.RELEASE.jar!/:5.2.8.RELEASE]

According to this log, I can't locate which requestMpping is the problem.

what I expecting in logs:

at class DemoController.demo,Failed to convert value of type 'java.lang.String' to required type 'java.lang.Long'; nested exception is java.lang.NumberFormatException: For input string: "undefined"

This is handled in DefaultHandlerExceptionResolver and we don't log exceptions that are handled. Where is the log message logged from? The exception itself provides access to the MethodParameter.
