在hibernate中引入proxool连接池之后，系统运行报错No suitable driver found for proxool；我用的是hibernate的Annotation形式，检查过driverurl没有问题，修改过proxool.xml的编码，不管用，换过mysql的驱动包，不管用
这是我的proxool.xml的配置
Xml代码
<?xml version="1.0" encoding="UTF-8"?>
<!--
the proxool configuration can be embedded within your own application's.
Anything outside the "proxool" tag is ignored.UTF-8
-->
<something-else-entirely>
<proxool>
<alias>DBProxool</alias>
<driver-url>jdbc:mysql://172.16.113.53:3306/hibernate</driver-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<driver-properties>
<property name="user" value="root" />
<property name="password" value="root" />

</proxool>
</something-else-entirely>
这是我的hibernate.cfg.xml配置
Xml代码
<?xml version='1.0' encoding='utf-8'?>

应该是你没有导入mysql的jar包
mysql-connector-java-5.0.4-bin.jar下载地址：
