我在dotspacemacs/user-config()下面增加了下面的配置，但是没有生效。请教下是什么原因？
(defun dotspacemacs/user-config ()
"Configuration for user code:
This function is called at the very end of Spacemacs startup, after layer
configuration.
Put your configuration code here, except for variables that should be set
before packages are loaded."

(define-key pyim-mode-map "." 'pyim-page-next-page)
(define-key pyim-mode-map "," 'pyim-page-previous-page) ;; page 翻页
(setq pyim-page-length 9) ;; page-length 每页显示词条数目
