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>
    <driver-url>jdbc:mysql://192.168.1.12:3306/dbname1</driver-url>

    <minimum-connection-count>2</minimum-connection-count>
    </proxool>
    
 <proxool>
    <alias>db10</alias>
    <driver-url>jdbc:mysql://192.168.1.10:3306/dbname2</driver-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>

    <house-keeping-test-sql>select current_date from dual</house-keeping-test-sql>

    <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">

<!-- Generated by MyEclipse Hibernate Tools.                   -->
<hibernate-configuration>

	<session-factory>
		<property name="dialect">
			org.hibernate.dialect.MySQLDialect
		</property>
		<property name="myeclipse.connection.profile">mysql</property>
		<property name="connection.driver_class">

		<property name="hibernate.proxool.pool_alias">db10</property>
		<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：

	<bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">

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。
