主要有两个注解

@RestControllerAdvice 或者 @ControllerAdvice

@ExceptionHandler(RuntimeException.class)

/**
     * 全局异常处理器
     *
     */
    @RestControllerAdvice
    public class GlobalExceptionHandler
    {
        private static final Logger log = LoggerFactory.getLogger(GlobalExceptionHandler.class);
    
        /**
         * 运行异常
         */
        @ExceptionHandler(RuntimeException.class)
        public AjaxResult runtimeException(RuntimeException e)
        {
            return AjaxResult.error(e.getMessage());
        }
    
        /**
         * 基础异常
         */
        @ExceptionHandler(BaseException.class)
        public AjaxResult baseException(BaseException e)
        {
            return AjaxResult.error(e.getMessage());
        }
    
        /**
         * 业务异常
         */
        @ExceptionHandler(CustomException.class)
        public AjaxResult businessException(CustomException e)
        {
            if (StringUtils.isNull(e.getCode()))
            {
                return AjaxResult.error(e.getMessage());
            }
            return AjaxResult.error(e.getCode(), e.getMessage());
        }
    
        @ExceptionHandler(NoHandlerFoundException.class)
        public AjaxResult handlerNoFoundException(Exception e)
        {
            log.error(e.getMessage(), e);
            return AjaxResult.error(HttpStatus.NOT_FOUND, "路径不存在，请检查路径是否正确");
        }
    
        @ExceptionHandler(AccessDeniedException.class)
        public AjaxResult handleAuthorizationException(AccessDeniedException e)
        {
            log.error(e.getMessage());
            return AjaxResult.error(HttpStatus.FORBIDDEN, "没有权限，请联系管理员授权");
        }
    }
