步驟一：編輯Tomcat的配置文件conf/server.xml在用於接受客戶端語法的Connector<connector></connector>標籤中添加URIEncoding="UTF-8"屬性，該屬性用來解決GET中的編碼問題。
xml 代碼
- <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" />
步驟二：在每個需要提交表單參數的JSP/Servlet之前加入下列代碼來設置字符集，用於搞定POST請求：
java 代碼
- request.setCharacterEncoding("UTF-8");
這樣基本就搞定了字符亂碼問題了，實現上述問題的要求是所有的網頁編碼必須是UTF-8編碼既。
在JSP中：
jsp 代碼
- <%@page contentType="text/html" pageEncoding="UTF-8"%>
在Servlet中：
java 代碼
- response.setContentType("text/html;charset=UTF-8");
在所有的網頁中：
html代碼
- <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
以上測試在Tomcat 6.0.14、IE6.0、FireFox2.0.13及Opera9.25中測試通過，開發環境使用netBeans 6.0
附測試代碼：
html代碼
