jsp页面生成html代码编码实现
具体实现：利用 filter 的过滤功能把 *.jsp 过滤出来，判断是否存在对应的 .html 文件，如果不存在对应的 .html 文件，则将其内容读出写入指定的 .html 文件，再跳转到对应的 .html 即可。如果存在对应的 .html 文件，则直接跳转到对应的 .html 即可。
代码：jspfilter.java

hreq.getrequesturl().lastindexof( "." ));
if (hreq.getrequesturl().indexof( ".jsp" ) != -1 && ( null == hreq.getparameter( "type" ) || hreq.getparameter( "type" ).equals( "" ))) {
hresp.sendredirect(hreq.getcontextpath()+ "/conversion ?name=" +hreq.getrequesturl());
return ;
}
chain.dofilter(request, response);
}
