关于OpenSessionInViewFilter，StrutsPrepareAndExecuteFilter的问题，请教各位！！！

Question

WEB.XML
中如果写成
<filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>
<filter>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <url-pattern>/*</url-pattern>
</filter-mapping>
可以实行懒加载的效果但是我过滤的功能
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter>
<filter-name>BehindFilter</filter-name>
<filter-class>com.bzu.Filter.BehindFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>BehindFilter</filter-name>
<url-pattern>/jsp/behind/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
BehindFilter类就没有办法用了要么去掉OpenSessionInViewFilter，这样过滤类就能其作用了，但是不能实现懒加载了，请问有什么好的方法没有，2个都能用，要怎么修改配置文件，还是新手，希望大家给点意见，多谢了

Answer 1

你的OpenSessionInViewFilter是写在BehindFilter前面还是后面哦，把BehindFilter写在OpenSessionInViewFilter的前面

Answer 2

<filter> 
  <filter-name>OpenSessionInViewFilter</filter-name> 
  <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter                  </filter-class>   <init-param> 
    <param-name>singleSession</param-name> 
    <param-value>true</param-value> 
  </init-param> 
</filter>延迟加载OpenSessionInViewFilter

Answer 3

这个我也有试过，但是写
<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
  </filter>的时候，Eclipse的WEB.XML好像报错，不过我会再试试看的，谢谢你的意见

Answer 4

写在后面的话
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>跟
<filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>有冲突
后面那个<filter-name>struts2</filter-name>前面会报错，出现一个小红叉的

Answer 5

去掉
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>就是先不了拦截功能了

Answer 6

<filter>
<filter-name>BehindFilter</filter-name>
<filter-class>com.bzu.Filter.BehindFilter</filter-class>
</filter>

  
<filter-mapping>
<filter-name>BehindFilter</filter-name>
<url-pattern>/jsp/behind/*</url-pattern>
</filter-mapping>
   <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>
<filter>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>试试看
