Question

我在使用hibernate 5时遇到了来自数据库的逆向工程问题。我能够生成hibernate.reveng.xml文件，但是当我使用Hibernate代码生成配置运行时，它会给出如下所述的错误。

我尝试过添加“hibernate”。我的xml文件，但同样的事情，我可以生成hibernate.reveng.xml但不能运行Hibernate代码生成配置。

这是我的xml文件：

<hibernate-configuration>
 <session-factory>
  <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
  <property name="connection.password">Password123!</property>
  <property name="connection.url">jdbc:sqlserver://localhost:1433;databaseName=TestDB</property>
  <property name="connection.username">sa</property>
  <property name="dialect">org.hibernate.dialect.SQLServer2012Dialect</property>
 </session-factory>
</hibernate-configuration>

这是我面临的错误。

Answer 1

试试这个。

将<property name="dialect">org.hibernate.dialect.SQLServer2012Dialect</property>更改为<property name="hibernate.dialect">org.hibernate.dialect.SQLServer2012Dialect</property>

Answer 2

我最终删除了整个配置文件并重做所有步骤，根据我发布的内容对我的pojo进行逆向工程，现在正在运行。但我不明白为什么。

无法逆向工程以在eclipse中使用hibernate生成pojo
