参考了很多网友的文章和文档.现将Spring+Hibernate+Proxool的配置发表如下:

    proxool.xml

  

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

<something-else-entirely>

  <proxool>

    <alias>DBPool</alias>

    <driver-url>jdbc:mysql://localhost:3306/db</driver-url>

    <driver-class>com.mysql.jdbc.Driver</driver-class>

    <driver-properties>

      <property name="user" value="root"/>

      <property name="password" value="123456"/>

    </driver-properties>

     <maximum-connection-count>50</maximum-connection-count>

      <minimum-connection-count>10</minimum-connection-count>

    <house-keeping-test-sql>select CURRENT_DATE</house-keeping-test-sql>

  </proxool>

</something-else-entirely>

applicationContext.xml

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

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

另外一种配置【很少见】：

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

    <property name="driverClassName">

    <value>org.logicalcobwebs.proxool.ProxoolDriver</value>

    </property>

    </bean>

   <bean id="sessionFactory" lazy-init ="true" 

    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">   

        <!--   依赖注入数据源，注入正是上文定义的dataSource-->   

        <property name="dataSource"><ref local="dataSource"/></property>   

        <property name="lobHandler" ref="lobHandler"/>

        

        <property name="mappingLocations">   

            <list>   

                <!--以下用来列出所有的PO映射文件-->

     <value>classpath:xxx/xxx/xxx/xx/xxx.hbm.xml</value>

            </list>   

        </property>   

        <!--定义Hibernate的SessionFactory的属性 -->   

        <property name="hibernateProperties">   

            <props>

            </props>   

        </property>
