还是Java Struts2.3 乱码问题。

无论啥语言都会遇到乱码问题，这里，大体给个乱码的解决方案，就是“一致性原则”。

1.页面方面

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

如果用到了js，等等传参数。可能会有浏览器差异，所以，通常用encodeURIComponent(name)进行编码

2.控制器，业务逻辑方面

 HttpServletRequest re = ServletActionContext.getRequest();	

re.setCharacterEncoding("UTF-8");

struts方面

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
    <constant name="struts.custom.i18n.resources" value="GlobalMessage" />
	<constant name="struts.locale" value="zh_CN" />
	<constant name="struts.i18n.encoding" value="UTF-8"/>
	<constant name="struts.devMode" value="true" />

3.数据库方面

conn = DriverManager.getConnection(ReadConfig.getReadconfig().getJdbcInfo().getUrl()+ReadConfig.getReadconfig().getJdbcInfo().getAp_005()+"?useUnicode=true&characterEncoding=UTF-8",
					ReadConfig.getReadconfig().getJdbcInfo().getUserName(),ReadConfig.getReadconfig().getJdbcInfo().getUserPass());

ps.executeQuery("set names utf8");

4.服务器方面，tomcat

 

    <Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443"  URIEncoding="UTF-8" />

实在不行，就加filter或者

keyword = new String(quer.getBytes("ISO-8859-1"),"UTF-8");
