Spring3, Hibernate3.6与Proxool连接池配置

鉴于Spring3.0不采用Servlet启动，改用listener,并且针对Mysql与DBCP连接池在linux服务器上超时连接的Bug,现简要地做Spring3与Proxool连接池的配置： 

1.Web.xml配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<!--启动连接池-->
<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/proxool.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

<!--启动spring(spring3.1)-->
<context-param>
<param-name>contextConfigLocation</param-name>

<param-value>
WEB-INF/classes/com/dx/bags/config/applicationContext.xml
</param-value>
</context-param>

<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>

</web-app>

proxool.xml<位于WEB-INF目录下，与web.xml同目录>
[b]本文中由于有多数据库连接，于是，做了多个配置。alias分别为db12,db10,db5[/b]

<?xml version="1.0" encoding="UTF-8"?>
<proxool-config>
<proxool>
<alias>db12</alias>

<maximum-connection-count>10</maximum-connection-count>

</proxool>

<maximum-connection-count>10</maximum-connection-count>
<minimum-connection-count>2</minimum-connection-count>
</proxool>

</proxool-config>


Hibernate.cfg.xml配置：
文件位于src目录下。

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<property name="hibernate.proxool.pool_alias">db5</property>
</session-factory>

</hibernate-configuration>


Spring 配置文件中对于datasource和sessionFactory配置片断：

关于proxool配置文件中的各参数就不多做说明了。很简单易懂。连接池所要JAR:proxool-0.9.1.jar，proxool-cglib.jar。
