Perhaps you don't have Joda-Time Hibernatein the classpath. It's needed for type="org.joda.time.contrib.hibernate.PersistentDateTime".
也许您的类路径中没有Joda-Time Hibernate。需要它type="org.joda.time.contrib.hibernate.PersistentDateTime"。
UPDATE:
更新：
It appears that Joda-time Hibernate support currently doesn't work with Hibernate 3.6, see PersistentDateTime doesn't work in hibernate 3.6 - ID: 3090209and Recompile Joda-Time Hibernate to make it work with Hibernate 3.6.
看来 Joda-time Hibernate 支持目前不适用于 Hibernate 3.6，请参阅PersistentDateTime 在 hibernate 3.6 中不起作用 - ID：3090209和重新编译 Joda-Time Hibernate 以使其与 Hibernate 3.6 一起工作。
You can use User Type projectinstead (type attribute becomes type="org.jadira.usertype.dateandtime.joda.PersistentDateTime").
您可以改用用户类型项目（类型属性变为type="org.jadira.usertype.dateandtime.joda.PersistentDateTime"）。
