java无法链接sql数据库

然后，我关闭了SQL Workbench而不对数据库进行任何更改。 我重新启动Liferay的Tomcat服务器，然后我得到了以下错误：

ERROR [localhost-startStop-1][DialectDetector:124] java.sql.SQLException:

Connections could not be acquired from the underlying database!

这个警告：

WARN [C3P0PooledConnectionPoolManager[identityToken->3c8jofUN]-HelperThread-#4][BasicResourcePool:1851]

com.mchange.v2.resourcepool.BasicResourcePool$ScatteredAcquireT[email protected] --

While trying to acquire a needed new resource, we failed to succeed more than

the maximum number of allowed acquisition attempts (3).

Last acquisition attempt exception:

PS。我使用的是最新版本的HSQL JDBC驱动程序(v.2.3.3)
