@WebServlet(name = "/ServletLife",urlPatterns = "/life",loadOnStartup = 1)
public class ServletLife extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        //原位置
//        PrintWriter writer = resp.getWriter();
        resp.setCharacterEncoding("utf-8");
        resp.setContentType("text/html;charset=utf-8");
        //新位置
        PrintWriter writer = resp.getWriter();
        writer.write("servlet life s宿舍");
        System.out.println("learn servlet life宿舍");
    }
}
