Hibernate3+mysql4 中文问题解决方案.

1, mysql安装时设置字符集utf-8（包括数据库字符集，以及表的字符集）, jdbc驱动用最新的
2. hibernate配置文件（hibernate.cfg.xml）中,加上属性
<property name="connection.useUnicode">true</property>
<property name="connection.characterEncoding">UTF-8</property>

3. web.xml设置Filter
=================================================

< filter >
   < filter-name >
   Set Web Application Character Encoding
   </ filter-name >
   < filter-class >com.util. SetEncodeFilter </ filter-class >
   < init-param >
    < param-name > defaultencoding </ param-name >
    < param-value > UTF-8 </ param-value >
   </ init-param >
  </ filter >
  < filter-mapping >
   < filter-name >
   Set Web Application Character Encoding
   </ filter-name >
   < url-pattern > /* </ url-pattern >
  </ filter-mapping >

=============================================

48    protected String selectEncoding(ServletRequest request) { 
49 
50        return this.defaultEncoding;

4.提交表单的jsp页面设置
<%@ page language="java"  contentType="text/html; charset=UTF-8"%>
