org.logicalcobwebs.proxool.ProxoolException: Attempt to register duplicate pool

Question

项目需要:允许在事务提交之后延迟加载显示所需要的对象.
既增加一个OpenSessionInViewFilter来把一个hibernate Session和一次完整的请求过程对应的线程相绑定.
之后在就在web.xml里面加入了如下一段话:
  <filter>
    <filter-name>OpenSessionInViewFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>OpenSessionInViewFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>加入后报错异常:java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?然后搜索资料,说是需要在web.xml里面再加入如下代码:
<context-param> 
<param-name> contextConfigLocation </param-name> 
<param-value> 
/WEB-INF/classes/applicationContext.xml 
</param-value> 
</context-param> 
<servlet> 
<servlet-name> context </servlet-name> 
<servlet-class> 
org.springframework.web.context.ContextLoaderServlet 
</servlet-class> 
<load-on-startup> 1 </load-on-startup> 
</servlet>加入以后报错异常:org.logicalcobwebs.proxool.ProxoolException: Attempt to register duplicate pool called 'mysql'
很多人都说是配置文件路径问题,我想应该不存在吧,在我没有加入上面两段代码的时候配置文件是没有问题的.
hibernate里面已写入以下代码:
<property name="hibernate.proxool.pool_alias">mysql</property>
<property name="hibernate.proxool.xml">proxool.xml</property>
<propertyname="hibernate.connection.provider_class">
          org.hibernate.connection.ProxoolConnectionProvider</property>
proxool.xml写入以下代码:
<driver-properties> 
<property name="user" value="root" /> 
<property name="password" value="root" />
</driver-properties>
<house-keeping-sleep-time>90000</house-keeping-sleep-time>
<maximum-new-connections>20</maximum-new-connections>
<prototype-count>3</prototype-count>
<maximum-connection-count>20</maximum-connection-count>
<minimum-connection-count>3</minimum-connection-count>
<test-before-use>true</test-before-use>
<test-after-use>true</test-after-use>
<house-keeping-test-sql>SELECT CURRENT_USER</house-keeping-test-sql>
</proxool> 
</something-else-entirely>
struts-config.xml写入一下代码:
 <message-resources parameter="com.weiyataike.struts.ApplicationResources" />
    <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
   <set-property property="contextConfigLocation" value="/WEB-INF/classes/applicationContext.xml" />
    </plug-in>
(已经把classpath改为/web-inf/classes)
请问哪位高人知道如何解决这个问题?我找了好多相关的帖子了,都没有给出具体的答案,基本上都是不了了之了.

Answer 1

把你WEB。XML这个文件贴出来看看 估计 你配置 配置文件的时候少了配了 或者忘记配了。
在就是 你防application的路径是不是对的

Answer 3

applicationContext.xml的路径就是:/WEB-INF/classes/applicationContext.xml 
这个不会有问题的.要有问题的话,早就给我报错了.
