没改过任何东西,就突然提示连不上数据库了!

提示的是No suitable driver,问题是我的配置文件都没有改过,昨天晚上还是正常运行的...dataSource:
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName">
<value>com.microsoft.sqlserver.jdbc.SQLServerDriver</value>
</property>
<property name="url">
<value>
jdbc:sqlserver://localhost:1433;databaseName=atcs
</value>
</property>
<property name="username">
<value>atcs</value>
</property>
<property name="password">
<value>123456</value>
</property>
</bean>

我的数据库是SQL Server 2005,已经把sqljdbc.jar放到编译路径和CLASSPATH里了...
调了一个下午还是这个问题,谁能帮帮忙啊!!

[wangnewton]

没见过，但确定一定是低级错误。呵呵
检查一下sql server是不是正确运行，或者再检查一下驱动

[Rick_ang]

SQL Server 2005正常运行,驱动我把原来的包删了重新加进行也不行...
而且这个应该跟数据库运行没关吧?他在加载Driver时就不行了....怎么会突然就有问题的呢??

你的databaseName=atcs重新起一个属性项试试：
<property name="url">
<value>
jdbc:sqlserver://localhost:1433
</value>
<property name="databaseName">
<value>atcs</value>
</property>

[dudusun]

我也遇到过这个问题,好好的程序突然就不能连接了,后来自己就又好了.可能是你的机器的问题把.你设了tomcat系统启动吗?重新启动一下看看

[guileen]

楼主我支持你 ----------------- 松自萧萧云自飘 风中独酌亦逍遥 抚却凡愁与尘念 琴韵未解恨已销

[Rick_ang]

顶

[Rick_ang]

在ClASSPATH里面,上面的配置应该也没错,我那天晚上还全部都能跑起来...现在就是不行了...在Eclipse的buildpath里面也把库删掉重加了..不知道还能有什么方法...

[Rick_ang]

你的databaseName=atcs重新起一个属性项试试：
<property name="url">
<value>
jdbc:sqlserver://localhost:1433
</value>
<property name="databaseName">
<value>atcs</value>
</property>

-----------------------
不行,没这个属性,现在是把包重新加了不行,dataSource也检查了好多遍了,这样的问题有可能是什么引起的??

[Rick_ang]

up,还是不行

[royeleo]

RPWT
或许明天就好了（*^_^*）

[火山企鹅]

你的SQL Server2005的JDBC驱动包你放在哪里了？在ClassPath了吗？

[Rick_ang]

解决了,原来就是因为对配置文件进行自动排版了!
