使用jboss工具/hibernate配置连接到数据库时发生java错误

Question

我正在尝试使用jboss工具hibernate代码生成为postgresql数据库中的表生成DAO和hibernate映射。我已经设置了hibernate配置，但当我尝试连接时，出现以下错误：

我在第54行查看了StandardBasicTypes，它的内容是public static final BooleanType BOOLEAN = BooleanType.INSTANCE;，我遵循了BooleanType字段。类BooleanType中确实存在的实例

我使用的是hibernate-core-4.1.8。最终的jar，hibernate-spatial-4.0-M1。在我的hibernate配置中，“hibernate版本”是“4.0”

Answer 1

这个问题与我的hibernate配置有关，特别是驱动程序和方言。最初，我

<property name="hibernate.connection.driver_class">org.postgis.DriverWrapper</property>
<property name="hibernate.dialect">org.hibernate.spatial.dialect.postgis.PostgisDialect</property>

我收到了上面问题中的错误堆栈跟踪。我把这些属性改成了

<property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>

并且能够通过hibernate工具连接到数据库。如果有人关心的话，我创建了一个JIRA here来跟踪问题，如果有人希望能够对地理空间对象使用hibernate工具
