struts2+spring+hibernate整合步骤

struts2、hibernate、spring所需jar包 
 
struts-core-2.x.x.jar  ----struts核心包 
xwork-core-2.x.x.jar   -----身体ruts在其撒很难过构建 
ognl-2.6.x.jar     ----对象导航语言 
freemarker-2.3.x.jar   ------struts2的ui标签的模板使用 
commons-fileupload-1.2.x.jar    ----文件上传组件 2.1.6版本后需加入此文件 
struts-spring-plugin-2.x.x.jar   ---用于struts2继承spring的插件 
 
hibernate核心安装包下的（下载路径：http://www.hibernate.org/ ，点击Hibernate Core 右边的download） 
hibernate2.jar 
lib\bytecode\hibernate-cglib-repack-2.1_3.jar 
lib\required\*.jar 
hibernate安装包下的（下载路径：http://www.hibernate.org/;点击Hibernate Annotations 右边的下载） 
hibernate-annotations.jar 
lib\ejb3-persistence.jar、hibernate-commons-annotations.jar 
hibernate针对JPA的实现包（下载路径：http://www.hibernate.org/ ，点击Hibernate Entitymanager右边下载）
 hibernate-entitymanager.jar 
lib\test\log4j.jar、  slf4j-log4j12.jar 
 
spring安装包下的 
dist\spring.jar 
lib\c3p0\c3p0-0.9.1.2.jar 
lib\aspecti\aspectjweaver.jar

1.先整合spring和hibernate 
  *将spring和hibernate的jar包放入lib下； 
  *创建spring的beans.xml配置文件
