Spring下配置proxool

发现网上讲hibernate + proxool的比较多。说spring的比较少。而且说得也不是太详细。
在spring下配置proxool 网上搜了一下，感觉有好几种配置,我就说一下我用的这种,配置成功了的这种,3个步骤:

1:在web.xml中配置两个servlet,一个是加载proxool配置文件的，一个是proxool的资源监控程序.

 <servlet>
   <servlet-name>proxoolServletConfigurator</servlet-name>
   <servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>
   <init-param>
    <param-name>xmlFile</param-name>
    <param-value>WEB-INF/classes/proxool-conf.xml</param-value>
   </init-param>
   <load-on-startup>1</load-on-startup>
  </servlet>
 <servlet>
   <servlet-name>AdminP</servlet-name>
   <servlet-class>org.logicalcobwebs.proxool.admin.servlet.AdminServlet</servlet-class>
  </servlet>
  <servlet-mapping>
   <servlet-name>AdminP</servlet-name>
   <url-pattern>/AdminP</url-pattern>
  </servlet-mapping>

<servlet>
  <servlet-name>proxoolServletConfigurator</servlet-name>
  <servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>
  <init-param>
   <param-name>xmlFile</param-name>
   <param-value>WEB-INF/classes/proxool-conf.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
 </servlet>
<servlet>
  <servlet-name>AdminP</servlet-name>
  <servlet-class>org.logicalcobwebs.proxool.admin.servlet.AdminServlet</servlet-class>
 </servlet>
 <servlet-mapping>
  <servlet-name>AdminP</servlet-name>
  <url-pattern>/AdminP</url-pattern>
 </servlet-mapping>

2:由于proxool只能管理它自己建立的连接,需要创建一个配置文件proxool-conf.xml,内容如下:

 <?xml version="1.0" encoding="utf-8"?>
<!-- the proxool configuration can be embedded within your own application's.
 Anything outside the "proxool" tag is ignored. -->
 <something-else-entirely>
 <proxool>
 <alias>spring_pro_pool</alias>
 <!--proxool只能管理由自己产生的连接-->
 <driver-url>jdbc:oracle:thin:@192.168.0.186:1521:ora90</driver-url>
 <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
 <driver-properties>
 <property name="user" value="admin"/>
 <property name="password" value="admin"/>
 </driver-properties>
 <!-- proxool自动侦察各个连接状态的时间间隔(毫秒),侦察到空闲的连接就马上回收,超时的销毁-->
 <house-keeping-sleep-time>90000</house-keeping-sleep-time>
 <!-- 指因未有空闲连接可以分配而在队列中等候的最大请求数,超过这个请求数的用户连接就不会被接受-->
 <maximum-new-connections>20</maximum-new-connections>
 <!-- 最少保持的空闲连接数-->
 <prototype-count>3</prototype-count>
 <!-- 允许最大连接数,超过了这个连接，再有请求时，就排在队列中等候，最大的等待请求数由maximum-new-connections决定-->
 <maximum-connection-count>10</maximum-connection-count>
 <!-- 最小连接数-->
 <minimum-connection-count>3</minimum-connection-count>
 <house-keeping-test-sql>select CURRENT_DATE from dual</house-keeping-test-sql>
 </proxool>
 </something-else-entirely>

<?xml version="1.0" encoding="utf-8"?> 
<!-- the proxool configuration can be embedded within your own application's. 
Anything outside the "proxool" tag is ignored. --> 
<something-else-entirely> 
<proxool> 
<alias>spring_pro_pool</alias> 
<!--proxool只能管理由自己产生的连接--> 
<driver-url>jdbc:oracle:thin:@192.168.0.186:1521:ora90</driver-url> 
<driver-class>oracle.jdbc.driver.OracleDriver</driver-class> 
<driver-properties> 
<property name="user" value="admin"/> 
<property name="password" value="admin"/> 
</driver-properties> 
<!-- proxool自动侦察各个连接状态的时间间隔(毫秒),侦察到空闲的连接就马上回收,超时的销毁--> 
<house-keeping-sleep-time>90000</house-keeping-sleep-time> 
<!-- 指因未有空闲连接可以分配而在队列中等候的最大请求数,超过这个请求数的用户连接就不会被接受--> 
<maximum-new-connections>20</maximum-new-connections> 
<!-- 最少保持的空闲连接数--> 
<prototype-count>3</prototype-count> 
<!-- 允许最大连接数,超过了这个连接，再有请求时，就排在队列中等候，最大的等待请求数由maximum-new-connections决定--> 
<maximum-connection-count>10</maximum-connection-count> 
<!-- 最小连接数--> 
<minimum-connection-count>3</minimum-connection-count> 
<house-keeping-test-sql>select CURRENT_DATE from dual</house-keeping-test-sql>
</proxool> 
</something-else-entirely>

3:最后一步,需要在spring的applicationContext.xml中引用刚才创建的配置文件,在其dataSource的地方加入:

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" destroy-method="close" singleton="true">
   <property name="driverClassName">
             <value>org.logicalcobwebs.proxool.ProxoolDriver</value>
         </property>
         <property name="url">
             <value>proxool.spring_pro_pool</value>
         </property>
  </bean>

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" destroy-method="close" singleton="true">
  <property name="driverClassName">
            <value>org.logicalcobwebs.proxool.ProxoolDriver</value>
        </property>
        <property name="url">
            <value>proxool.spring_pro_pool</value>
        </property>
 </bean>

在创建sessionFactory时只需要在hibernateProperties中加入下面三个属性配置就行了。

<property name="hibernateProperties">
    <props>
     <prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>
     <prop key="hibernate.cglib.use_reflection_optimizer">true</prop>
     <prop key="hibernate.show_sql">false</prop>
    </props>
   </property>

<property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>
    <prop key="hibernate.cglib.use_reflection_optimizer">true</prop>
    <prop key="hibernate.show_sql">false</prop>
   </props>
  </property>

倒此已经配置完了，需要注意的几个地方就是proxool在web.xml中的加载顺序必须在spring之前.两个配置文件中的alias必须一直,否则就出错了
