The problem is I am getting the exception:
问题是我收到了异常：
org.hibernate.MappingException: Association references unmapped class: info.domain.User
at org.hibernate.cfg.HbmBinder.bindCollectionSecondPass(HbmBinder.java:2380)

at org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:140)
The mapping of the list is creating the problem. What I am doing wrong?
列表的映射正在产生问题。我做错了什么？
Edit:
编辑：
This two configuration resides in different file, if these two are placed in same xml then the problem is not occurring.
这两个配置驻留在不同的文件中，如果将这两个配置放在同一个 xml 中，则不会出现问题。

please add a reference to the mapping file (which maps info.domain.User) into hibernate.cfg.xml.
请将映射文件（映射info.domain.User）的引用添加到 hibernate.cfg.xml 中。

Please add class level annotations to register the class as a Spring bean, i.e @Entity in this case since you are not using xml configuration.
请添加类级别注释以将该类注册为 Spring bean，即在本例中为 @Entity，因为您没有使用 xml 配置。
