对web.xml 的几点配置心得。包括mime-mapping

1.指定了自己的javaEncoding
(参考 http://gceclub.sun.com.cn/staticcontent/html/sunone/app7/app7-dg-webapp/ch6/ch6-4.html    
<servlet>
        <servlet-name>jsp</servlet-name>
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
        <init-param>
            <param-name>fork</param-name>
            <param-value>false</param-value>
        </init-param>
                <init-param>
            <param-name>javaEncoding</param-name>
            <param-value>GB18030</param-value>
        </init-param>
        <init-param>
            <param-name>xpoweredBy</param-name>
            <param-value>true</param-value>
        </init-param>
        <load-on-startup>3</load-on-startup>
    </servlet>


2.添加rar,iso等的mime-type映射
避免在浏览器里直接打开。


<mime-mapping>
<extension>mht</extension>
<mime-type>text/x-mht</mime-type>
</mime-mapping>
<mime-mapping>
        <extension>rar</extension>
        <mime-type>application/octet-stream</mime-type>
    </mime-mapping>
    <mime-mapping>
        <extension>iso</extension>
        <mime-type>application/octet-stream</mime-type>
    </mime-mapping>
    <mime-mapping>
        <extension>ape</extension>
        <mime-type>application/octet-stream</mime-type>
    </mime-mapping>
    <mime-mapping>
        <extension>rmvb</extension>
        <mime-type>application/octet-stream</mime-type>
    </mime-mapping>
    <mime-mapping>
        <extension>ico</extension>
        <mime-type>image/x-icon</mime-type>
    </mime-mapping>

   <mime-mapping>
   <extension>doc</extension>  
<mime-type>application/msword</mime-type>  
</mime-mapping>  
<mime-mapping>  
   <extension>xls</extension>  
   <mime-type>application/vnd.ms-excel</mime-type>  
</mime-mapping>  
<mime-mapping>  
   <extension>ppt</extension>  
   <mime-type>application/vnd.ms-powerpoint</mime-type>  
</mime-mapping>


3.对html静态页面设置编码

<!--  修改下面两行以支持静态超文本的自动编码
  -->
 <mime-mapping>
  <extension>htm</extension> 
  <mime-type>text/html;charset=gb2312</mime-type> 
  </mime-mapping>
 <mime-mapping>
  <extension>html</extension> 
  <mime-type>text/html;charset=gb2312</mime-type> 
  </mime-mapping>
  </web-app>
