Hibernate配置文件错误提示,The content of element type "list" must match ,怎么解决呢.The content of element type "list" must match "(meta*,subselect?,cache?,synchronize*,comment?,key,(index|list-index),(element|one-to-many|many-to-many|composite-element|many-to-any),loader?,sql-insert?,sql-update?,sql-delete?,sql-delete-all?,filter*)".配置文件如下,出错在list那一行.
