import java.io.IOException;

public class RedirectServlet extends HttpServlet {


    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          response.sendRedirect("a.jsp");
    }
}

3.配置web.xml文件

    <servlet-class>RedirectServlet</servlet-class>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>RedirectServlet</servlet-name>
    <url-pattern>/redirect</url-pattern>
  </servlet-mapping>
