hibernate+proxool的数据库连接池配置方法

阅读更多

下面我介绍一下在使用Hibernate 3.0做数据执久层解决方案时，怎么配置Proxool 0.8.3数据库连接池的方法。  

1、将proxool-0.8.3.jar以及连接数据库用到的jar文件包含在你的项目的classpath或者WEB-INF/lib下面，本例使用的是MS Sqlserver数据库。  

2、在和hibernate.cfg.xml平级的目录新建一个proxoolconf.xml文件，添加以下文件内容：  

     xml 代码

xml version="1.0" encoding="utf-8"?>
<something-else-entirely>
<proxool>
<alias>proxoolPoolalias>

<driver-url>jdbc:microsoft:sqlserver://192.168.0.5:1433;DatabaseName=videopublishdriver-url>
<driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriverdriver-class>
<driver-properties>
<property name="user" value="jdbc_user"/>
<property name="password" value="memory"/>
driver-properties>

<house-keeping-sleep-time>90000house-keeping-sleep-time>

<maximum-new-connections>20maximum-new-connections>

<prototype-count>5prototype-count>

<maximum-connection-count>100maximum-connection-count>

<minimum-connection-count>10minimum-connection-count>
proxool>
something-else-entirely>

3、以上就是proxool所需的配置文件，下面就是hibernate.cfg.xml文件的配置了，也很简单，文件内容如下：  

xml 代码

xml version='1.0' encoding='UTF-8'?>

          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
