SSH整合学习笔记之spring与hibernate整合（二）--C3P0
SSH整合学习笔记
现在将之前的spring与hibernate整合修改一下，使用C3P0数据库连接池。基本的配置没有改变，只是增加了一个jdbc.properties文件和修改了applicationContext.xml和hibernate.cfg.xml文件的相关配置。
jdbc.properties
jdbcUrl= jdbc:mysql:///spring2hibernate
driverClass = com.mysql.jdbc.Driver
username = root
password =rootapplicationContext.xml

</hibernate-configuration>只要做了如上所述的修改就完成了使用c3p0数据库连接池的配置。大大的提高的安全性和灵活性。
