+/**
+ * 这个监听器在web应用启动时检查在web应用根目录下是否有文件名为customMenu.json的文件，
+ * 如果有，则删除原微信公众号的菜单，按文件内容创建新菜单。
+ * customMenu.json文件的内容要符合微信公众平台自定义菜单创建接口标准。
+ * CustomMenuLoadListener需要在web.xml中配置才能生效，配置格式如下：
+ *
+ * com.halo.servlet.listeners.CustomMenuLoadListener
+ *
+ *
+ * 注意：CustomMenuLoadListener的配置需要放在filter和ContextLoaderListener（如果有的话
+ * ）的配置之后，servlet（如果有的话）的配置之前。
+ * 开发者可以在web.xml的context-param节中指定自己的菜单文件名，param-name为customMenuLocation，如下例：
+ *
+ * customMenuLocation
+ * myMenu.json
+ *
+ * 注意：
+ * 1. 菜单文件只能有一个，不要试图添加多个菜单文件名，那样找不到任何菜单文件；
+ * 2. 修改或添加新的菜单文件后，需重启web应用才会生效；
+ * 3. 如果要删除原菜单又不创建新菜单，请在web应用根目录下放置一个名为“deleteMenu.json”的空文件；
+ * 4.
+ * 菜单文件也可以放在web应用根目录下的任意子目录中，在配置文件路径时使用相对于web应用根目录的路径，例如：resources\myMenu.json
