Struts2 + Spring3 + Hibernate3.6(JPA2) + Proxool9 集成环境搭建

注意事项：

1、不要使用Hibernate自带的cglib-2.2.jar，听网上说会与Spring的冲突，可用cglib-nodep-2.2.jar代替

2、如果使用MSSQL2000数据库，除了它的驱动包外还要下载jtds-1.2.5.jar，因为Hibernate在管理MSSQL2000需要，不然会访问不到数据库

3、Hibernate3会调用slf4j-log4j12-1.6.1.jar中的类，但官网上下的Hibernate3中没有带

4、使用AOP所需要的JAR包aopalliance-1.0.jar，aspectjrt-1.5.3.jar，aspectjweaver-1.5.3.jar，commons-logging-1.1.1.jar
