整合Spring+Struts2+Hibernate

运行报严重:

Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.mchange.v2.c3p0.ComboPooledDataSource]: No default constructor found; nested exception is java.lang.NoClassDefFoundError: com/mchange/v2/ser/Indirector

问题原因：缺省mchange-commons-java-0.2.3.4.jar包

解决办法：导入“mchange-commons-java-0.2.3.4.jar”或复制到lib目录下
