这样配置错在哪，该怎么改

Answer 1

<property name="hibernate.connection.url">jdbc:mysql:///mysql</property>

不知道你的数据库是什么，我给你看下我的

Answer 2

参考这个链接
http://hi.baidu.com/wd_tianyi/blog/item/5dc42b1b256981d3ac6e751a.html
<property name="connection.provider_class">
com.liusoft.dlog4j.db.DataSourceConnProvider</property>
<property name="dscp.datasource">org.apache.commons.dbcp.BasicDataSource</property>
<property name="dscp.driverClassName">sun.jdbc.odbc.JdbcOdbcDriver</property>
<property name="dscp.url">jdbc:odbc:dlog4j</property>
<property name="dscp.username">admin</property>
<property name="dscp.password"></property>
<property name="dscp.initialSize">1</property>
<property name="dscp.maxActive">200</property>
<property name="dscp.maxWait">2000</property>
<property name="dscp.defaultAutoCommit">false</property>
<property name="dscp.defaultReadOnly">false</property>
<property name="dscp.removeAbandoned">true</property>
<property name="dscp.removeAbandonedTimeout">120</property>
<!--
<property name="dscp.defaultTransactionIsolation">1</property>
-->
<property name="dscp.poolPreparedStatements">true</property>
<property name="dscp.maxOpenPreparedStatements">1000</property>

在上面的配置信息中，connection.provider_class是Hibernate本身用来指定不同ConnectionProvider实现类。接下来我们规定了我们的扩展所使用的配置键值都是以dscp.开头，同时我们使用dscp.datasource来指定具体实现了DataSource接口的类名，例如如果使用DBCP这个连接池，那么这个类名应该是org.apache.commons.dbcp.BasicDataSource。对于其他以dscp.开头的且不是dscp.datasource的配置信息都会直接赋值给DataSource的实现类。例如上面的配置中，driverClassName、url、username、password等配置信息都是BasicDataSource类的属性。

追问

我是想关联俩个映射文件，hfuu/edu/yl/bean/UserInfo.hbm.xml与hfuu/edu/yl/bean/AccountInfo.hbm.xml
