大家跟著做就可以了，這個代碼還可以在修改讓他傳遞個文件名稱，生成文件，按照傳遞的參數(shù)實現(xiàn)文件名稱，大家自己修改下

toHtml.java(不用修改,直接用)

把jsp輸出的內(nèi)容寫到xxx.htm

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>
使用方法很簡單
mytest.jsp(wwwroot下)
<a
href="web/tohtm?urls=/kszx/kszx.jsp">生成靜態(tài)頁</a>
kszx.jsp為要生成htm的動態(tài)頁
如果不在wwwroot下,在wwwroot/pp下
就要寫成
<a
href="../web/tohtm?urls=/kszx/kszx.jsp">生成靜態(tài)頁</a>
