1、Hiebernate配置文件中引用proxool配置文件：

<hibernate-configuration>  
 <session-factory>  
  <property name="proxool.pool_alias">DBPool</property>  
     <property name="proxool.xml">proxool.xml</property>  
     <property name="connection.provider_class">  
         org.hibernate.connection.ProxoolConnectionProvider  
     </property>  
    
  <property name="show_sql">true</property>  
  <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>   
    
 </session-factory>  
</hibernate-configuration>  

　　

2、直接在spring配置文件中配置proxool，无proxool.xml配置文件

<bean id="dataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource" destroy-  
  
method="reset">  
 <property name="driver" value="com.mysql.jdbc.Driver" />  
    <property name="driverUrl" value="jdbc:mysql://localhost/activemq?  
  
user=root&password=root" /><!--必须在这里配置用户名/密码,下面的貌似没用-->  
    <property name="user" value="root" />  
    <property name="password" value="root" />  
    <property name="alias" value="jms1" />  
    <property name="houseKeepingSleepTime" value="90000" />  
    <property name="prototypeCount" value="5" />  
    <property name="maximumConnectionCount" value="100" />  
    <property name="minimumConnectionCount" value="10" />  
</bean>  

　　

3、spring配置文件中直接配置Hibernate，引用proxool配置文件,无需Hibernate.xml

 1 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">  
 2  <property name="hibernateProperties">  
 3   <props>  
 4    <prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>  
 5    <prop key="hibernate.show_sql">true</prop>  
 6    <prop key="hibernate.cglib.use_reflection_optimizer">true</prop>  
 7    <prop   
 8   
 9 key="connection.provider_class">org.hibernate.connection.ProxoolConnectionProvider</prop>  
10    <prop key="hibernate.proxool.xml">proxool.xml</prop>  
11    <prop key="hibernate.proxool.pool_alias">DBPool</prop>  
12       
13   </props>  
14  </property>  
15 .............  
16 </bean>  

 

4、spring配置文件中引用proxool配置文件，spring配置文件中直接配置Hibernate

http://blog.csdn.net/xingfeng0501/article/details/7475050

 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName">
    <value>org.logicalcobwebs.proxool.ProxoolDriver</value>
    </property>
    <property name="url">
    <value>proxool.db</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>   
                <!-- 指定Hibernate的连接方言-->   
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>   
                <!-- 不同数据库连接，启动时选择create,update,create-drop   -->
                <prop key="hibernate.hbm2ddl.auto">update</prop> 
                <prop key="hibernate.show_sql">false</prop> 
     <prop key="connection.useUnicode">true</prop>
     <prop key="connection.characterEncoding">UTF-8</prop>
                
            </props>   
        </property> 
        
       
    </bean>

 

5、结合以上2和3的方式，在spring配置文件中直接配置Hibernate和proxool，无需Hibernate.xml和proxool.xml配置文件。（这种方式纯属以上方式的总结，未实践）

proxool详细配置：https://www.2cto.com/database/201110/109272.html

//获得数据库连接的语句

Connection conn=DriverManager.getConnection("proxool.dbname");
