很奇怪，很多人都说proxool很好，
但是搜索spring中配置proxool作 数据源连接池的资料却几乎找不到详细点的。
因此自己整理如下：
先下载:
http://surfnet.dl.sourceforge.net/sourceforge/proxool/proxool-0.9.0RC2.zip
web.xml
-------------------------
<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/proxool.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet>
<servlet-name>proxooladmin</servlet-name>
<servlet-class>org.logicalcobwebs.proxool.admin.servlet.AdminServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>proxooladmin</servlet-name>
<url-pattern>/proxooladmin</url-pattern>
</servlet-mapping>

proxool.xml
-------------------------
<?xml version="1.0" encoding="UTF-8"?>
<proxool-config>
<proxool>

</driver-properties>
<maximum-connection-count>10</maximum-connection-count>
<house-keeping-test-sql>select 1 from dual</house-keeping-test-sql>
</proxool>
</proxool-config>
spring里：
两种配置：
a: <!-- 与上面的proxool以及web.xml里结合使用-->
<bean id="mainDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>org.logicalcobwebs.proxool.ProxoolDriver</value>
</property>
<property name="url">
<value>proxool.blogdb</value>
</property>
</bean>
b:<!-- 单独的类似dbcp的使用-->
<bean id="mainDataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource" destroy-method="close">
<property name="driver">
<value>oracle.jdbc.driver.OracleDriver</value>
</property>
<property name="driverUrl">
<value>jdbc:oracle:thin:lizongbo/password@127.0.0.1:1521:ORADB</value>
<!--用户名和密码写在一起才调用成功,不然会报 调用无效的参数 错误，下面设置用户名和密码的property好像是无效的，其它数据库也是这样
比如mysql的也要把用户名和密码写在url里：<property name="driverUrl" value="jdbc:mysql://localhost:3306/blogdb?user=lizongbo&password=lizongbo" />
-->
</property>
<property name="user"> <!-- 必须在这里也设置，但是 proxool却不使用它，或许是个bug-->
<value>lizongbo</value>
</property>
<property name="password"> <!-- 必须在这里也设置，但是 proxool却不使用它，或许是个bug-->
<value>lizongbo</value>
</property>
<property name="alias">
<value>lizongbo</value>
</property>
<property name="houseKeepingSleepTime">
<value>90000</value>
</property>
<property name="prototypeCount">
<value>5</value>
</property>
<property name="maximumConnectionCount">
<value>100</value>
</property>
<property name="minimumConnectionCount">
<value>10</value>
</property>
<property name="trace">
<value>true</value>
</property>
<property name="verbose">
<value>true</value>
</property>
</bean>
