一、spring 处理请求字符编码

<filter>  
        <filter-name>characterEncodingFilter</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>characterEncodingFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>

二、配置监听器ContextLoaderListener

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

三、配置applicationContext的xml文件

<context-param>  
         <param-name>contextConfigLocation</param-name>  
         <param-value>classpath:spring/applicationContext.xml</param-value>  
     </context-param>

四、配置静态资源的访问

<servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.css</url-pattern>  
    </servlet-mapping>  
    <servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.swf</url-pattern>  
    </servlet-mapping>  
    <servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.gif</url-pattern>  
    </servlet-mapping>  
    <servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.jpg</url-pattern>  
    </servlet-mapping>  
    <servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.png</url-pattern>  
    </servlet-mapping>  
    <servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.js</url-pattern>  
    </servlet-mapping>  
    <servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.html</url-pattern>  
    </servlet-mapping>  
    <servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.xml</url-pattern>  
    </servlet-mapping>  
    <servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.json</url-pattern>  
    </servlet-mapping>  
    <servlet-mapping>  
        <servlet-name>default</servlet-name>  
        <url-pattern>*.map</url-pattern>  
    </servlet-mapping>

五、配置spring MVC 的DispatcherServlet

<servlet>  
       <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <init-param>  
            <param-name>contextConfigLocation</param-name>  
              
              
              
              
              
            <param-value>classpath:spring/dispatcher-servlet.xml</param-value>  
        </init-param>  
        <load-on-startup>1</load-on-startup>
    </servlet>  
    <servlet-mapping>  
        <servlet-name>DispatcherServlet</servlet-name>  
          
          
          
        <url-pattern>/</url-pattern>   
    </servlet-mapping>

六、指定特殊页面

<welcome-file-list>  
       <welcome-file>login.html</welcome-file>  
    </welcome-file-list>  
    <error-page>   
        <error-code>404</error-code>  
        <location>/nopage.html</location>  
    </error-page>  
    <error-page>   
        <exception-type>java.lang.NullPointerException</exception-type>  
        <location>/error.html</location>  
    </error-page>

七、指定会话超时

<session-config>  
        <session-timeout>360</session-timeout>  
    </session-config>
