下面是全局异常处理程序类

package com.app.exception_handler;

import java.time.LocalDateTime;

import org.springframework.dao.EmptyResultDataAccessException;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.http.converter.HttpMessageNotReadableException;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.context.request.WebRequest;
import org.springframework.web.servlet.mvc.method.annotation.ResponseEntityExceptionHandler;

import com.app.custom_exceptions.UserHandlingException;
import com.app.dto.ErrorResponse;

@ControllerAdvice
public class GlobalExceptionHandler extends ResponseEntityExceptionHandler{
    
    @ExceptionHandler(RuntimeException.class)
    public ResponseEntity<?> handleRuntimeException(RuntimeException e) {
        System.out.println("in handle run time exc " + e);
        ErrorResponse resp = new ErrorResponse(e.getMessage(), LocalDateTime.now());
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(resp);
    }
    
    @ExceptionHandler(EmptyResultDataAccessException.class)
    public ResponseEntity<?> handleEmptyDataExcetpion(EmptyResultDataAccessException e) {
        System.out.println("in handle  exc " + e);
        ErrorResponse resp = new ErrorResponse(e.getMessage(), LocalDateTime.now());
        return ResponseEntity.status(HttpStatus.NOT_FOUND).body(resp);
    }

    @ExceptionHandler(UserHandlingException.class)
    public ResponseEntity<?> handleUserHandlingException(UserHandlingException e) {
        System.out.println("in handle user exc " + e);
        ErrorResponse resp = new ErrorResponse(e.getMessage(), LocalDateTime.now());
        return ResponseEntity.status(HttpStatus.NOT_FOUND).body(resp);
    }
    
    @Override
    protected ResponseEntity<Object> handleMethodArgumentNotValid(MethodArgumentNotValidException ex,
            HttpHeaders headers, HttpStatus status, WebRequest request) {
        System.out.println("in handle invalid meth args ");
        StringBuilder sb = new StringBuilder("Validation Errors : ");
        ex.getBindingResult().getFieldErrors().forEach(e -> sb.append(e.getDefaultMessage()+" "));
        return ResponseEntity.status(HttpStatus.BAD_REQUEST)
                .body(new ErrorResponse(sb.toString(), LocalDateTime.now()));
    }

我已经测试了这个代码片段--应用程序可以正常启动。
IllegalStateException表示在非法或不适当的时间调用了某个方法。换句话说,Java环境或Java应用程序不处于所请求的操作的适当状态。
