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>


=============================================
SetEncodeFilter.java

 1package com.util;
 2
 3import java.io.IOException;
 4
 5import javax.servlet.Filter;
 6import javax.servlet.FilterChain;
 7import javax.servlet.FilterConfig;
 8import javax.servlet.ServletException;
 9import javax.servlet.ServletRequest;
10import javax.servlet.ServletResponse;
11
12public class SetEncodeFilter implements Filter { 
13     
14    protected FilterConfig filterConfig = null; 
15 
16    protected String defaultEncoding = null; 
17 
18    /**//* (non-Javadoc) 
19     * @see javax.servlet.Filter#init(javax.servlet.FilterConfig) 
20     */ 
21    public void init(FilterConfig arg0) throws ServletException { 
22        // TODO Auto-generated method stub 
23        this.filterConfig = arg0; 
24        this.defaultEncoding = filterConfig.getInitParameter("defaultencoding"); 
25    } 
26 
27    /**//* (non-Javadoc) 
28     * @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain) 
29     */ 
30    public void doFilter( 
31        ServletRequest request, 
32        ServletResponse response, 
33        FilterChain chain) 
34        throws IOException, ServletException { 
35        // TODO Auto-generated method stub 
36        request.setCharacterEncoding(selectEncoding(request)); 
37        chain.doFilter(request, response); 
38    } 
39 
40 
41    public void destroy() { 
42         
43        this.defaultEncoding = null; 
44        this.filterConfig = null; 
45    } 
46 
47 
48    protected String selectEncoding(ServletRequest request) { 
49 
50        return this.defaultEncoding; 
51    } 
52 
53} 

 

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