出现该异常的原因是原来的Hibernate的连接池的连接速度以及管理模式都不够好,所以本人换了
第三方的c3p0连接池.之后就出现了这个异常.在网上查了一下
原因
在手工事务模式 (AutoCommit=false) 下,如果使用直接 (SelectMethod=direct) 模式,当您尝试对使用 JDBC 驱动程序的 SQL Server 数据库执行多个语句时,将会出现此问题。直接模式是该驱动程序的默认模式。
回到顶端
解决方案
当您使用手工事务模式时,必须将驱动程序的 SelectMethod 属性设置为 Cursor,或者确保您按照本文“更多信息”一节指定的方式在每个连接上只使用一个活动语句
解决方法:
<property name="connection.username">***</property>
<property name="connection.url">
jdbc:microsoft:sqlserver://192.168.18.254:1433;DatabaseName=comjt;SelectMethod=Cursor
</property>
<property name="dialect">
net.sf.hibernate.dialect.SQLServerDialect
</property>
<property name="myeclipse.connection.profile">t</property>
<property name="connection.password">***</property>
<property name="connection.driver_class">
com.microsoft.jdbc.sqlserver.SQLServerDriver
</property>
<property name="show_sql">true</property>
<property name="connection.useUnicode">true</property>
<property name="connection.characterEncoding">GBK</property>
Can't open connection
附录:
checked在html:radio html:select html:checkbox语法里面是没有的
可以借助js来实现
在</html>后面加
<script>
document.all("xxx")[0].checked=true;
</script>
