ERROR: HHH000099: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session): org.hibernate.AssertionFailure: null id in hiberna.Student entry (don't flush the Session after an exception occurs)

右上角的 “hibernate基础jar包” 就是老师从 hibernate-release-4.2.4.Final/lib/required 复制到 hibernate-core 中的所有jar包。不用再找hibernate-release-4.2.4.Final这个文件了，直接导入就行。
