在網上有很多這方面文章,依照上面也解決過,但是修改了mysql的配置文件my.ini.感覺在部署時不是很爽.

這里給出另一種解決方法(mysql-4.1.11).低版本的mysql似乎沒出現過中文問題(mysql-4.0.17). :)

1.添加一個過濾器,將字符集編碼設為UTF-8.
修改web.xml:

 <filter>
  <filter-name>SetCharacterEncoding</filter-name>
  <filter-class>hxz.filter.SetEncodingFilter</filter-class>
  <init-param>
   <param-name>encoding</param-name>
   <param-value>UTF-8</param-value>
  </init-param>
 </filter>
 
 <filter-mapping>
  <filter-name>SetCharacterEncoding</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>

新建一個過濾器:
package hxz.filter;

import java.io.IOException;

import javax.servlet.*;

public class SetEncodingFilter implements Filter {
 
 // default character encoding
 String defaultEncoding = "UTF-8"; 
 
 public void init(FilterConfig config) throws ServletException {
  String encoding = config.getInitParameter("encoding");
  if (encoding != null) {
   defaultEncoding = encoding;
  }
 }

 public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
  request.setCharacterEncoding(defaultEncoding);
  chain.doFilter(request, response);
 }

 public void destroy() {
  defaultEncoding = null;
 }

}

2.修改hibernate配置文件:
<property name="url">
  <value>jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=UTF-8</value>
</property>
注意后面的:useUnicode=true&amp;characterEncoding=UTF-8, 在xml中&要改為;amp;

3.在新版本中mysql建表時,你可以選擇一種字符集,將它設為utf-8.
jsp或servlet中把字符集改為UTF-8.
