在搭建ssh2的开发环境时，经常会遇到包冲突的问题，原因是struts, hibernate 和spring 引入了各自的开发包，这些开发包有些互相冲突，导致了各个版本的集成，常常不是一番风顺。其中asm 和 cglib 的冲突在使用annotation时经常出现， 我使用的环境是struts2.3.4 + hibernate 4 + spring 3.1, 全部通过Annotation的方式集成，在集成的过程中出现了以下问题。 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 'loginService' defined in file [D:tomcat7apache-tomcat-dev-7.0.29webappswhyonlyWEB-INFclassescomwhyonlypermissionserviceLoginService.class]: Initialization of bean failed;
