web.xml
中添加
<servlet>
<servlet-name>tohtm</servlet-name>
<servlet-class>com.jetsum.mystatic.toHtml</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>tohtm</servlet-name>
<url-pattern>/web/tohtm</url-pattern>
</servlet-mapping>
使用方法很简单 mytest.jsp(wwwroot下)
<a href="web/tohtm?urls=/kszx/kszx.jsp">生成静态页</a> kszx.jsp为要生成htm的动态页
如果不在wwwroot下,在wwwroot/pp下
就要写成
<a href="../web/tohtm?urls=/kszx/kszx.jsp">生成静态页</a> |
