SSH中web.xml文件的配置

Struts:

如果是2.1.3之前的版本，用org.apache.struts2.dispatcher.FilterDispatcher，否则，用org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter。 从Struts2.1.3开始，将废弃ActionContextCleanUp过滤器，而在StrutsPrepareAndExecuteFilter过滤器中包含相应的功能

 1 <!-- Struts2 filter --> 2     <filter> 3         <filter-name>struts2CleanupFilter</filter-name> 4         <filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class> 5     </filter> 6  7     <filter> 8         <filter-name>struts2Filter</filter-name> 9         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>10     </filter>

如果程序报类找不到异常，且后面有 org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter  等信息，可能是你的版本问题.解决方法是确定你的struts版本， 如果是2.1.3之前的版本，用 org.apache.struts2.dispatcher.FilterDispatcher，以后的版本则配置org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

Hibernate：

1 <!-- Hibernate Open Session In View filter -->2     <filter>3         <filter-name>hibernateOpenSessionInViewFilter</filter-name>4         <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>5     </filter>
