一、实现Servlet
    基本设置：
    request.setCharacterEncoding("UTF-8");
    response.setCharacterEncoding("UTF-8");
    response.setContentType("text/html");

    获取值：
    String requestURI = request.getRequestURI();
    String method = request.getMethod();
    String param = request.getParameter("param");

    输出：
    PrintWriter out = response.getWriter();
    out.println();
    document.lastModified
    location
    out.flush();
    out.close();

二、配置<Servlet>
    <servlet>
      <servlet-name></servlet-name>
      <servlet-class></servlet-class>
      <init-param>
        <param-name></param-name>
        <param-value></param-value>
      </init-param>
      <load-on-startup></load-on-startup>
    </servlet>
    getServletContext().getInitParm(String paramName)

三、配置<Servlet-mapping>
    <servlet-mapping>
      <servlet-name></servlet-name>
      <url-pattern></url-pattern>
    </servlet-mapping>
