我正在使用Spring开发RESTful应用程序。我想要处理POST请求体中数据类型错误的情况

@RestControllerAdvice
public class GlobalExceptionHandler {

    @ExceptionHandler(BadRequestException.class)
    public ResponseEntity<String> handleBadRequestException(BadRequestException ex) {
        return ResponseEntity.status(HttpStatus.BAD_REQUEST).body(ex.getMessage());
    }
}

@RestController
public class MyController {

    @PostMapping("/api/data")
    public ResponseEntity<String> processData(@Valid @RequestBody DataRequest request) {
        // 处理请求数据
        // ...
        return ResponseEntity.ok("Data processed successfully");
    }
}

public class DataRequest {
    @NotNull(message = "Field 'name' is required")
    private String name;

    @Min(value = 18, message = "Field 'age' must be at least 18")
    private int age;

    // Getters and setters
}

public class BadRequestException extends RuntimeException {
    public BadRequestException(String message) {
        super(message);
    }
}
