以下为dic_left.jsp代码片断，是utf-8编码，点击查询，会把limitTest（品名）通过js提交给dic_left.jsp，limitValue接受到值后做处理。问题是：在js里alert出来的中文是好的，但是提交给dic_left.jsp的limitValue打出来的是乱码，用什么方法可以解决，前提是要用utf-8，不能用gbk。
<%@ page contentType= "text/html; charset=utf-8 " %>
<script language= "javascript ">
function query(){
alert(window.document.formX.limitTest.value);
window.location = "dic_left.jsp?limitValue= "+window.document.formX.limitTest.value;
}
</script>
<form name= "formX ">
limitValue = request.getParameter( "limitValue ");
System.out.println( "limitValue "+limitValue);
品名: <input type= "test " name= "limitTest " value= " ">
<input type= "button " value= "查询 " class= "an1 " onClick= "query() ">
</form>
------解决方案--------------------
环境：
WindowsXP中文
Eclipse3.2.1+Myeclipse5.1.0GA
Tomcat5.5
JDK1.5.0
Hibernate3.1
Mysql5.0+ mysql-connector-java-5.0.4-bin.jar
方案：
1.集成开发环境Eclipse中设置文本文件存储编码为UTF-8。
//我想是因为….如果所做工程项目最终要在别的版本操作系统的服务器上跑，这里需要设置（未经证实）
2.数据库mysql，默认编码使用utf8；
并且创建数据库时在语句后面追加DEFAULT CHARSET=utf8;set names utf8;
//如果数据库默认编码是utf8，那这个也不是必需的吧（未经证实）
3.跟数据库连接的URL：Hibernate URL:
jdbc:mysql://127.0.0.1:3306/addressbook?useUnicode=true&characterEncoding=utf8
//如果数据库默认编码是utf8，那这个也不是必需的吧（未经证实）
4.使用过滤器，过滤器文件代码见后面附1。
<filter>
<filter-name> Set Character Encoding </filter-name>
<filter-class> org.biti.filters.SetCharacterEncodingFilter </filter-class>
<init-param>
<param-name> encoding </param-name>
<param-value> UTF-8 </param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name> Set Character Encoding </filter-name>
<url-pattern> /* </url-pattern>
</filter-mapping>
//过滤的是post还是get还没弄明白，据说只过滤器中一个，另一个见5。
5.修改Tomcat配置文件server.xml中Connector部分
<Connector port= "80 "
maxHttpHeaderSize= "8192 "
maxThreads= "150 " minSpareThreads= "25 " maxSpareThreads= "75 "
enableLookups= "false " redirectPort= "8443 " acceptCount= "100 "
connectionTimeout= "20000 " disableUploadTimeout= "true " />
加入URIEncoding= "UTF-8 "一项。
//我现在这个没乱码的就没有设置….
附1：SetCharacterEncodingFilter.java(可在Tomcat示例源码中找到)
