目前对遇到jsp中文及其乱码问题做个总结

1 struts2配置 2 数据库 3 页面 4 jdbc连接 5 tomcat
以下解决方法不分顺序,大家按照自己的配置对比.
1 struts2配置
struts2在配置struts.properties文件中加上struts.i18n.encoding=UTF-8 或者在struts.xml里加上<constant name="struts.i18n.encoding" value="UTF-8" /> 有的朋友说加上struts.locale=zh_CN,但是我的struts.locale为en_GB没有问题.
2 数据库
2.1 mysql的表的编码方式,其DDL应该为: ENGINE=InnoDB DEFAULT CHARSET=utf8; 可以使用show create table tbname查看.
2.2 安装mysql数据库时就应该以utf8编码默认安装查看mysql数据库默认编码方式可以在其目录下my.ini文件中找到mysql和mysqld下default-character-set值为utf8或者在mysql数据库命令行下以"\s;"查看.
3 页面
每个页面上加上<%@page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8" %> 这样在jsp页面里,点右键,查看编码方式则为UTF-8.
4 jdbc连接
设置characterencoding为UTF-8 如jdbc.mysql.url=jdbc:mysql://localhost:3306/db?useUnicode=true&amp;characterEncoding=UTF8
5 tomcat
为了保证get/post数据都采用相同的UTF8编码，我们在server.xml中进行了如下设置: <Connector port="8080" protocol="HTTP/1.1"                connectionTimeout="20000"                redirectPort="8443"  URIEncoding="UTF-8" />
其中,当当使用IIS作为webserver转发servlet/jsp请求时IIS是通过AJP协议，把请求转发到Tomcat监听的8009端口,所以需要配置端口8009的URIEncoding为UTF-8.
     msyql数据库安装时候需要默认编码方式或者使用MySQL Server Instance Config Wizard 配置,
在设置Configure the MySQL Server 5.0 server instance那里的时候选择Manual Selected Default Character Set / Collation 为 UTF8 而不是默认的 LATIN1 在MYSQL里查看得 mysql> \s;
