Java Web开发中的中文乱码问题的处理办法，jsp、javabean、servlet等稍改动后均适用。
-------------------JAVA代码------------------

1. packagetools;
2. 
   
3. importjavax.servlet.http.HttpServlet;
4. importjavax.servlet.Filter;
5. importjavax.servlet.FilterConfig;
6. importjavax.servlet.ServletRequest;
7. importjavax.servlet.ServletResponse;
8. importjavax.servlet.FilterChain;
9. 
   
10. publicclassEncodingFilterextendsHttpServletimplementsFilter
11. {
12. privateFilterConfigconfig=null;
13. privateStringtargetEncoding="GBK";
14. 
    
15. publicvoidinit(FilterConfigfilterConfig)
16. {
17. this.config=filterConfig;
18. this.targetEncoding=config.getInitParameter("encoding");
19. }
20. 
    
21. publicvoiddestroy()
22. {
23. config=null;
24. targetEncoding=null;
25. }
26. 
    
27. publicvoiddoFilter(ServletRequestservletRequest,ServletResponseservletResponse,
28. FilterChainfilterChain)
29. {
30. ServletRequestrequest=(ServletRequest)servletRequest;
31. try
32. {
33. request.setCharacterEncoding(targetEncoding);
34. filterChain.doFilter(servletRequest,servletResponse);
35. }
36. catch(Exceptionex)
37. {
38. ex.printStackTrace();
39. }
40. }
41. 
    
42. }
43. 
    

------------web.xml------------

1. <filter>
2. <filter-name>EncodingFilter</filter-name>
3. <filter-class>db.EncodingFilter</filter-class>
4. <init-param>
5. <param-name>encoding</param-name>
6. <param-value>GBK</param-value>
7. </init-param>
8. </filter>
9. <filter-mapping>
10. <filter-name>EncodingFilter</filter-name>
11. <url-pattern>/*</url-pattern>
12. </filter-mapping>
13. 
    

在sqlserver2000和mysql中试验通过。
