关于jdbc + mysql utf-8 乱码

1.JDBC URL
   <property name="jdbcUrl">
      <value>jdbc:mysql://localhost:3306/lei?useUnicode=true&amp;characterEncoding=UTF-8</value>
   </property>


2.用MySQL命令查询：show variables like "%char%";显示：
character_set_client     utf8
character_set_connection     utf8
character_set_database     utf8
character_set_filesystem     binary
character_set_results     utf8
character_set_server    utf8
character_set_system    utf8

3.MY.INI
[client]
port=3306

[mysql]

default-character-set=utf-8

[mysqlID]

character-set=utf-8

4.程序本身（在action里面写了防止乱码的代码）
// 获得servletAPI
HttpServletResponse response = ServletActionContext.getResponse();
HttpServletRequest request = ServletActionContext.getRequest();


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