本文介绍如何在web.xml中配置字符编码过滤器，确保网页显示正确无乱码。

import java.io.*;
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 SetCharacterEncodingFilter implements Filter {
	protected String encoding = null;
	public void destroy() {
		this.encoding = null;
	}
	public void init(FilterConfig filterConfig) throws ServletException
	{
		this.encoding = filterConfig.getInitParameter("encoding");
	}
	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain chain) throws IOException, ServletException
	{
		request.setCharacterEncoding(encoding);
		response.setContentType("text/html;charset=" + encoding);
		chain.doFilter(request, response);
	}
}

web.xml配置如下:

	<filter>
		<filter-name>SetCharacterEncodingFilter</filter-name>
		<filter-class>
			com.smzbtv.filter.SetCharacterEncodingFilter
		</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>SetCharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

注意: 以上web.xml里对转码的配置必须放在Struts2配置前面
