Answer 1

不知道你的规则是什么，如果只是GET的话可以用Filter。如果是post的话会有问题。Filter
package test;import java.io.IOException;
import java.util.Enumeration;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;/**
 *
 * @author oushuuryuu
 */
public class TestRedirectFilter implements Filter {    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        redirect((HttpServletRequest)request, (HttpServletResponse)response);
    }    @Override
    public void destroy() {
    }    private void redirect(HttpServletRequest request, HttpServletResponse response) {
        String uri = request.getRequestURI();        String newURL = uri.replaceAll(".do", ".html");        Enumeration<String> paramNms = request.getParameterNames();
        while (paramNms.hasMoreElements()) {
            String paramName = paramNms.nextElement();
            newURL = newURL.concat("_").concat(paramName).concat(request.getParameter(paramName));
        }
        try {
            response.sendRedirect(newURL);
        } catch (IOException ex) {
            Logger.getLogger(TestRedirectFilter.class.getName()).log(Level.SEVERE, null, ex);
        }
        
    }}
web.xml    <filter>
        <filter-name>RedirectFilter</filter-name>
        <filter-class>test.TestRedirectFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>RedirectFilter</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>

Answer 2

查询下 urlrewrite 方面资料 里面有提到 urlrewrite.jar   把它添加到项目中  然后再WEB-INF下配置下 urlrewrite重写规则 之后就可以访问了  

Answer 3

类似
<urlrewrite>
    <rule>
        <from>XXXX.html_XX([0-9]+)</from>
        <to type="redirect">/XXXX.do\?XX=$1</to>
    </rule>
</urlrewrite>
