JSP中Servlet过滤问题
为什么不过滤啊？大侠们帮我看看吧。谢谢！

package encoding;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class encodingFilter implements Filter {
private FilterConfig config;
private String Encoding="iso8859-1";

public void destroy() {
config=null;

}

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

public void init(FilterConfig con) throws ServletException {
this.config=con;
String s=config.getInitParameter("Encoding");
if(s!=null)
{
this.Encoding=s;
System.out.println(Encoding);
}

}

}








XML

<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>encoding.encodingFilter</filter-class>
<init-param>
<param-name>Encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
   





------解决方案--------------------
在request.setCharacterEncoding(Encoding);
的下面加上response.setCharacterEncoding(Encoding);试试看
