1.设置struts的字符编码，能够在struts.xml中添加下面代码：

<constant name="struts.i18n.encoding" value="GBK" />

### This can be used to set your default locale and encoding scheme
# struts.locale=en_US
struts.i18n.encoding=GBK

2.设置JSP页面字符编码：

<%@ page language="java" contentType="text/html; charset=GBK"
    pageEncoding="GBK"%>

<Connector URIEncoding="GBK" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" />

public static String changeEncoding(String s, String oldEncoding, String newEncoding) {
		String result = null;
		try {
			result = new String(s.getBytes(oldEncoding), newEncoding);
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		}
		return result;
	}
