web.xml配置文件

1、spring配置文件加载

<!-- spring文件加载 --><context-param>   <param-name>contextConfigLocation</param-name>        <param-value>classpath:spring/applicationContext*.xml</param-value> </context-param><listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>

下面这种配置可以参考下，配置多个目录下的配置文件

<context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:spring/*.xml,classpath:org/codehaus/xfire/spring/xfire.xml</param-value></context-param>

2、session过滤器配置

</pre><pre>

 <!-- session过滤器配置 --><filter><filter-name>login</filter-name><filter-class>com.llbt.filter.SessionFilter</filter-class></filter><filter-mapping><filter-name>login</filter-name><url-pattern>*.action</url-pattern></filter-mapping><filter-mapping> <filter-name>login</filter-name> <url-pattern>*.do</url-pattern></filter-mapping><filter-mapping> <filter-name>login</filter-name> <url-pattern>*.jsp</url-pattern></filter-mapping>

3、struts2配置

struts2的配置文件struts.xml默认路径是类路径

类路径:web容器的classes目录下，项目工程的sourceFolder(常见的有src，也可自己创建)

修改默认路径，可参见：

http://blog.163.com/wunan_23/blog/static/1955623202011102105925798/

<!-- struts2配置 -->  <filter>    <filter-name>Struts2</filter-name>    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter>  <filter-mapping>    <filter-name>Struts2</filter-name>    <url-pattern>*.do</url-pattern> </filter-mapping>  <filter-mapping>   <filter-name>Struts2</filter-name>    <url-pattern>*.action</url-pattern>  </filter-mapping>  

4、log4j配置

<!-- log4j生成日志文件路径配置 -->  <context-param><param-name>webAppRootKey</param-name><param-value>project.gold.app</param-value></context-param><context-param><param-name>log4jConfigLocation</param-name><param-value>WEB-INF/classes/log4j.properties</param-value></context-param><listener><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class></listener>

5、session超时配置

 -1 表示永不超时     （单位分）

可参照：http://lhp--2006.iteye.com/blog/1312273

<session-config>     <session-timeout>-1</session-timeout> </session-config>

6、字符集配置

   字符集配置可参见：http://hi.baidu.com/feiyuetengkong/item/c9d8dbdf21a370e2b3f777f2

<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><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>*.do</url-pattern></filter-mapping><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>*.jsp</url-pattern></filter-mapping>

7、servlet配置

servlet的一般配置是

  <servlet>    <servlet-name>ImageServlet</servlet-name>    <servlet-class>com.servlet.ImageServlet</servlet-class>  </servlet>  <servlet-mapping>    <servlet-name>ImageServlet</servlet-name>    <url-pattern>/imageServlet</url-pattern>  </servlet-mapping></span>

若需要配置web容器启动时候就加载执行的servlet，配置如下：

<servlet><servlet-name>serviceFactoryInitServlet</servlet-name><servlet-class>com.llbt.common.servlet.ServiceFactoryInitServlet</servlet-class><load-on-startup>3</load-on-startup></servlet></span>

第一种servlet在被拦截的地址匹配url-pattern时候执行；第二种servlet在web容器启动时候执行。

load-on-startup表示servlet的加载顺序，数值越小，加载优先级越高。

8、springMVC配置

<servlet><servlet-name>springMvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springMVC.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>springMvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping>
