给你贴一个吧 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 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 {
        // Conditionally select and set the character encoding to be used
        if (ignore || (request.getCharacterEncoding() == null)) {
            String encoding = selectEncoding(request);            if (encoding != null) {
                request.setCharacterEncoding(encoding);
            }
        }        // Pass control on to the next filter
        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);
    }
}然后再到web.xml里面加入下面的语句
  <filter>
    <filter-name>Set Character Encoding</filter-name>
    <filter-class>包路径.SetCharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>gb2312</param-value>
    </init-param>
    <init-param>
      <param-name>ignore</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  
     <filter-mapping>
    <filter-name>Set Character Encoding</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
