Hibernate集合映射,hibernate,Hibernate,我对Hibernate集合映射有点迷茫。尝试在Eclipse Hibernate透视图中添加持久性配置会引发以下问题： Invalid ORM mapping file. Error parsing XML (line14 : column 16): The content of element type "list" must match "(meta*,subselect?,cache?,synchronize*,comment?,key,(index|list-index),(elemen

我对Hibernate集合映射有点迷茫。尝试在Eclipse Hibernate透视图中添加持久性配置会引发以下问题：

Invalid ORM mapping file.
Error parsing XML (line14 : column 16): 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*)".
Error parsing XML (line17 : column 15): The content of element type "map" must match "(meta*,subselect?,cache?,synchronize*,comment?,key,(map-key|composite-map-key|map-key-many-to-many|index|composite-index|index-many-to-many|index-many-to-any),(element|one-to-many|many-to-many|composite-element|many-to-any),loader?,sql-insert?,sql-update?,sql-delete?,sql-delete-all?,filter*)".

实际映射配置如下所示：

顺序是特定的（并在错误消息中提供给您）。这不是hibernate，而是XML模式
因此，请正确确定标签的顺序，例如：
需要在
等
编辑：
并不是所有的桌子都错了。第一个没问题。第二个有两个错误，应该是

您的第三个报价是错误的，因为它在class=“core.User”之后缺少一个报价，应该是

感谢您的快速回答。我并不清楚顺序可能很重要，但我会尝试。JB Nizet-不是在第二个区块中。我尝试根据错误描述中的顺序更改顺序，但没有效果。请参阅更新的答案。2和3错误，无法正常工作，2不正常，3错误为你的答案唱一首歌。我会改变配置并报告。
