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");
    }
}
