jsp+html的编码问题：
<%@ page language="java" contentType="text/html; charset=utf-8" %>
<%@ page language="java" pageEncoding="utf-8" %>
jsp要使用UTF-8编码，html要使用UTF-8编码，在eclipse可用右键文件——>format修改
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
action中文编码：
因为jsp文件用的是utf-8编码，所以服务器要一致
server.xml
<Connector URIEncoding="UTF-8" port="8080" protocol="HTTP/1.1"
connectionTimeout="20000" redirectPort="8443" />
struts.xml:
<constant name="struts.i18n.encoding" value="UTF-8"></constant>
