我用过的一些web.xml配置

<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>

encodingFilter针对request的内容进行编码

 

<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>flushMode</param-name>
<param-value>AUTO</param-value>
</init-param>
</filter>

待续…..

 

<listener>
<listener-class>com.hello.common.web.EnviromentInitContextListener</listener-class>
</listener>

com.hello.common.web.EnviromentInitContextListener这个listener implements ServletContextListener

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

org.springframework.web.context.ContextLoaderListener也是implements ServletContextListener

可见，装着Listener的都应该是list。
