解决办法：更改Hibernate.cfg.xml文件内容<property name="dialect"> org.hibernate.dialect.SQLServerDialect </property>改为<property name="hibernate.dialect">
org.hibernate.dialect.SQLServerDialect </property>
以前用的是eclipse4.0：<property name="dialect"> org.hibernate.dialect.SQLServerDialect </property>
eclipse 5.o应该设置为：<property name="hibernate.dialect"> org.hibernate.dialect.SQLServerDialect </property>
以上结论错误，等我重启后，问题依然存在，以前这个程序用在myeclipse4.0上,
以上测试错误是用在myeclipse5.5上造成的，
所以我还是在myeclipse4.0上运行，问题真正得到解决。
