Servlet—HttpServletRequest与HttpServletResponse对象常用方法

public class ServletTest extends HttpServlet {
       @Override
       protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {     
              //设置响应类型
              response.setContentType("text/html");
              //设置字符编码
              response.setCharacterEncoding("UTF-8");
              //设置响应正文
              response.getWriter().print("3秒后跳转到注册页面");
              //转发和重定向
              request.getRequestDispatcher("http://www.baidu.com").forward(request,response)
              response.sendRedirect("http://www.baidu.com");
              /**
               * forward和redirect的区别
               * forward:是服务器端进行跳转，地址栏不发生变化
               * redirect:是客户端获取地址重新进行访问，地址栏发送变化
               */
       @Override
       public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
              doGet(request, response);
       }
}
