Hibernate连接SqlServer时的小问题

在使用Hibernate连接SqlServer时，会出现如下错误：

org.hibernate.cfg.JDBCBinderException: Duplicate class name 'CheckConstraints' generated for 'org.hibernate.mapping.Table

(test.sys.check_constraints)'. Same name where generated for 'org.hibernate.mapping.Table(test.sys.check_constraints)'
Duplicate

class name 'CheckConstraints' generated for 'org.hibernate.mapping.Table(test.sys.check_constraints)'. Same name where generated

for 'org.hibernate.mapping.Table(test.sys.check_constraints)'
  <No message>

 

这是因为在数据库中有其它的系统表参与了逆向生成，出现的错误。解决方法：配置逆向文件hibernate.reveng.xml，设定只有需要的表才参与逆向生成。

生成的文件内容：
