你hibernate配置文件中是否有 <property name="hibernate.hbm2ddl.auto">update</property> 这个配置 其它几个参数的意思: validate 加载hibernate时，验证创建数据库表结构 create 每次加载hibernate，重新创建数据库表结构 create-drop 加载hibernate时创建，退出是删除表结构 update 加载hibernate自动更新数据库结构 感觉你在启动时，去创建或者更新了数据库中的表而导致启动时间很长。 如果有，把这行配置去掉试试。

只在真的改过表示结构时才启用 hbm2ddl，初始化完成之后以后再启动时关闭hbm2ddl省时间。

为什么我启动tomcat 并没有加载hibernate.cfg.xml

[指尖de柔情]

我的项目也是这个问题，已经解决：<property name="hibernate.hbm2ddl.auto">update</property>
