經測試沒問題

1>程序使用UTF-8
2>編碼過慮為UTF-8??????//影響post提交
3>server.xml加URIEncoding="UTF-8"?//影響get提交
4>jsp頁面用<%@ page pageEncoding="UTF-8"%>
5>htm頁面用<meta http-equiv="content-type" content="text/html; charset=UTF-8">

注意：get提交不能直接在地址欄輸入測試，要在頁面里轉向.

用到的配置：

?? < filter >

???? < filter-name > encoding </ filter-name >

???? < filter-class > com.util.EncodingFilter </ filter-class >

???? < init-param >

?????? < param-name > encoding </ param-name >

?????? < param-value > UTF-8 </ param-value >

???? </ init-param >

?? </ filter >

?? < filter-mapping >

???? < filter-name > encoding </ filter-name >

???? < url-pattern > /* </ url-pattern >

?? </ filter-mapping >
