启动tomcat时,报错:Attempt to register duplicate pool called "eSale"
Hibernate配置连接池proxool出错：
启动tomcat时,报错：Attempt to register duplicate pool called "eSale"
错误原因：重复注册连接池：eSale（连接池别名）
如果在hibernate.cfg.xml已经配置proxool，如下：

<property name="hibernate.proxool.pool_alias">eSale</property><property name="hibernate.proxool.xml">  proxool.xml</property><property name="hibernate.connection.provider_class">  org.hibernate.connection.ProxoolConnectionProvider</property><property name="dialect">  org.hibernate.dialect.SQLServerDialect</property><property name = "hibernate.proxool.existing_pool">  false</property>//这里为false，则在web.xml里面不用配置如下内容,反之可以//------------------------------------------------<servlet><servlet-name>ServletConfigurator</servlet-name><servlet-class>  org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class><init-param>  <param-name>xmlFile</param-name>  <param-value>WEB-INF/classes/proxool.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet>//--------------------------------------------------
