ProxoolConf.xml配置如下

 <something-else-entirely>
  <proxool>
    <alias>mysqlProxool</alias>

</something-else-entirely>hibernate.cfg.xml配置如下
<!-- 配置连接池 proxool--> 

<property name="proxool.pool_alias">mysqlProxool</property> 
<property name="proxool.xml">/WEB-INF/ProxoolConf.xml</property> 
<property name="connection.provider_class">org.Hibernate.connection.ProxoolConnectionProvider</property> 
<property name="hibernate.proxool.existing_pool">true</property>  同时把hibernate.cfg.xml放在了web-inf下
ProxoolConf放在了src下
求解决。
