我正在尝试设置一个简单的hibernate + maven项目。我按照Java presistence with hibernate第2章中提到的步骤进行操作（只有差异是我使用而不是Ant）。但是，在尝试使用maven hibernate 3 plugin生成架构时，似乎无法创建所需的表。

答案 0 :(得分：2)
我认为DDL创建的问题在于它无法找到hibernate配置文件。尝试删除pom文件中路径上的前导斜杠。所以该行应如下所示：
<configurationfile>src/main/resources/hibernate.cfg.xml</configurationfile>
要自动创建数据库，请将以下属性添加到hiberante.cfg.xml
<property name="hibernate.hbm2ddl.auto">create</property>
