S2SH框架整合教学教材

1、Good is good, but better carries it.精益求精，善益求善。S2SH框架整合建立一个Web工程添加Hibernate支持org.hibernate.dialect.Oracle9Dialectjdbc:oracle:thin:7:1521:orclscotttigeroracle.jdbc.driver.OracleDriverOrcl添加Spring框架的支持添加Struts2框架的支持添加struts.xml和web.Xml配置Struts2的容器对象是Spring配置Spring容器，是其在Web容器启动是实例化ApplicationContextStru
