用STRUTS+SRPING+HIBERNATE 做一个应用，在数据库操作时候出现以下错误
HTTP Status 500 - --------------------------------------------------------------------------------type Exception reportmessage description The server encountered an internal error () that prevented it from fulfilling this request.exception javax.servlet.ServletException: Hibernate operation: Cannot open connection; uncategorized SQLException for SQL [???]; SQL state [null]; error code [0]; Cannot create PoolableConnectionFactory (Access denied for user 'root'@'localhost' (using password: YES)); nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user 'root'@'localhost' (using password: YES))

</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value>csywy</value>
</property>
</bean>
找了很久也没有找出来原因？
请大家帮忙

Answer 1

Access denied for user 'root'@'localhost' (using password: YES)); root 密码错了！

Answer 2

我也出现相同的问题了
  可是我的配制文件都是对啊 也没有空格
  我配制文件如下：
  
  <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
</property>
<property name="url">
<value>jdbc:microsoft:sqlserver://localhost:1433</value>
</property>
<property name="username">
<value>sa</value>
</property>
<property name="password">
<value>sa</value>
</property>
</bean>
