web遇到的乱码解决

经测试没问题

1>程序使用UTF-8
2>编码过虑为UTF-8 //影响post提交
3>server.xml加URIEncoding="UTF-8" //影响get提交
4>jsp页面用<%@ page pageEncoding="UTF-8"%>
5>htm页面用<meta http-equiv="content-type" content="text/html; charset=UTF-8">

注意：get提交不能直接在地址栏输入测试，要在页面里转向.

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 >

// EncodingFilter.java
