The problem is I am getting the exception:问题是我遇到了异常:
org.hibernate.MappingException: Association references unmapped class: info.domain.User
at org.hibernate.cfg.HbmBinder.bindCollectionSecondPass(HbmBinder.java:2380)
at org.hibernate.cfg.HbmBinder.bindListSecondPass(HbmBinder.java:2231)
at org.hibernate.cfg.HbmBinder$ListSecondPass.secondPass(HbmBinder.java:2729)

at org.hibernate.cfg.Configuration.generateSchemaUpdateScript(Configuration.java:936)
at org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:140)
The mapping of the list is creating the problem.列表的映射正在产生问题。 What I am doing wrong?
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.这两个配置位于不同的文件中,如果这两个配置在同一个 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, ie @Entity in this case since you are not using xml configuration.请添加 class 级别注释以将 class 注册为 Spring bean,即 @Entity 在这种情况下,因为您没有使用 Z0F635D0EZ8F328 配置。
