小记

<servlet>

    <servlet-name>default</servlet-name>

    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>

    <init-param>

        <param-name>debug</param-name>

        <param-value>0</param-value>

    </init-param>

    <init-param>

        <param-name>listings</param-name>

        <param-value>false</param-value>

    </init-param>

    <init-param> <param-name>fileEncoding</param-name> <param-value>utf-8</param-value> </init-param>

    <load-on-startup>1</load-on-startup>

</servlet>

1. tomcat web.xml 若无此配置 会以操作系统默认编码来读取

2. 不显示友好http错误信息可以调试程序

3. struts1 和 struts2的区别

• struts1 servlet
• struts2 filter
• filter > servlet
