开始学习JSF的时候有遇上中文问题，看了一些文章后突然想起Struts也有中文问题，当时用Filter解决的，我想应该也一样的，后来在工程里加入后中文问题解决了。多方便啊。

贴出代码

web.xml部分

Set Character Encoding
comm.CN.SetCharacterEncodingFilter

encoding
GBK

Set Character Encoding
/*

javabean部分

package comm.CN;

import java.io.IOException;
import javax.servlet.*;

public class SetCharacterEncodingFilter implements Filter
{

protected String encoding = null;
protected FilterConfig filterConfig = null;
protected boolean ignore = true;

public void destroy() {
this.encoding = null;
this.filterConfig = null;
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
if (ignore || (request.getCharacterEncoding() == null)) {
String encoding = selectEncoding(request);
if (encoding != null)
request.setCharacterEncoding(encoding);
}
chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws ServletException {

this.filterConfig = filterConfig;
this.encoding = filterConfig.getInitParameter("encoding");
String value = filterConfig.getInitParameter("ignore");
if (value == null)
this.ignore = true;
else if (value.equalsIgnoreCase("true"))
this.ignore = true;
else if (value.equalsIgnoreCase("yes"))
this.ignore = true;
else
this.ignore = false;
}
protected String selectEncoding(ServletRequest request) {
return (this.encoding);
}
}
