我遇到了这个例外：

1266 [main] INFO org.hibernate.tool.hbm2ddl.SchemaExport - Running hbm2ddl schema export
1266 [main] INFO org.hibernate.tool.hbm2ddl.SchemaExport - exporting generated schema to database

请帮我解决这个问题。这是我的配置文件：

 <hibernate-configuration> 
 <session-factory> 
 <property name="hibernate.connection.driver_class">sun.jdbc.odbc.JdbcOdbcDriver</property>
 <property name="hibernate.connection.username"></property>
 <property name="connection.password"></property> 
 <property name="connection.pool_size">1</property>
 <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property> 
 <property name="hibernate.conn.url">jdbc:odbc:demo</property>

Answer 1

检查你的hibernate属性名称。

hibernate.conn.url

应该是：

hibernate.connection.url

你的

connection.passsword

应该是

hibernate.connection.password

其余看起来不错，但重新检查了文档。我看到你有一个空的密码字段和用户名属性。你的odbc连接是否需要名称和密码？

如果您缺少登录凭据等其他信息，修复连接字符串至少会给您一种新的错误。

这些xml配置非常挑剔！
