Eclipse下面的Maven管理的SSH框架整合（Struts,Spring,Hibernate)

搭建的环境：eclispe下面的maven web项目

Struts:    2.5.10

Spring:    4.3.8

Hibernate:   5.1.7 .Final

MySQL:   5.1.30

先来详细的讲解一下SSH框架的整合，在这里是将struts2.0的Action的创建工作由Spring进行统一管理，主要是利用了Spring

控制反转和依赖注入的功能。

而将hibernate.cfg.xml整合Spring的配置文件中。而且利用Spring的面向切向功能对Hibernate事务进行统一管理。给实体类添加注解，表明了与表之间的映射关系，将Hibernate中的SessionFactory配置到了Spring的配置文件下面。就是注入连接池。

最后在这里我讲一下我在这里遇到过的问题以及解决方法吧，在struts2中默认是多实例（Prototype),每个请求都会产生相应的action实例去处理，但是spring整合之后，就由Spring管理bean，默认是单例模式，Action继承actionSupport会检验数据，如果转换出错，会找到你要input视图。没配就出错找不到。但是继续访问该action还是会报错，因为是单例，上次的异常还在，因为没有清除，所以继续出错返回input可以给action加上@Scope（”prototype")singleton单例模式
