java web自学视频教程第20章基于SSH2的网络商城在eclipse中调试运行时出现错误如下：
Struts Problem Report
Struts has detected an unhandled exception:
Messages:
A ResourcePool could not acquire a resource from its primary factory or source.
Connections could not be acquired from the underlying database!
Could not open connection
File: com/mchange/v2/resourcepool/BasicResourcePool.java
WARNING: com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@bcda51 -- Acquisition Attempt Failed!!! Clearing pending acquires. While trying to acquire a needed new resource, we failed to succeed more than the maximum number of allowed acquisition attempts (30). Last acquisition attempt exception:
java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)
不知道是什么原因？是否跟数据库有关？数据库连接的配置是在哪个地方进行设置，请协助解决谢谢
