tomcat的jpa（Hibernate）春天

Question

我正在使用JPA（Hibernate）和Spring项目这些天，我配置了spring，jpa并尝试在tomcat7上部署应用程序，因为我知道jpa/hibernate使用实体类创建表第一次加载，但是在应用程序启动时，我看不到数据库和应用程序之间的任何连接，下面您可以看到我的配置，我看到很多关于此问题的问题，我无法找到适当的解决方案。

任何一个可以告诉我是什么问题了这儿过得创建的应用程序，而不在码头服务器的任何问题的某个时候回来， 预先感谢您

Answer 1

我想有一个与您的配置，尝试删除后无问题“默认延迟实例=真” attribu TE

干杯

Answer 2

尝试改变：

<property name="hibernate.hbm2ddl.auto" value="validate"/> 

到：

<property name="hibernate.hbm2ddl.auto" value="update"/> 

或：

<property name="hibernate.hbm2ddl.auto" value="create"/>
