编写Servlet中的updateOldeerServlet：

package com.test.web;

import com.test.pojo.Older;
import com.test.service.OlderService;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@WebServlet("/updateOlderServlet")
public class updateOlderServlet extends HttpServlet {
    private OlderService service = new OlderService();
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        request.setCharacterEncoding("UTF-8");
        String height=request.getParameter("height");
        String weight=request.getParameter("weight");
        String name = request.getParameter("name");
        //封装对象
        Older older = new Older();
        older.setHeight(Integer.parseInt(height));
        older.setWeight(Integer.parseInt(weight));
        older.setName(name);
        service.update(older);
        request.getRequestDispatcher("/selectAllolder").forward(request,response);

    }

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        this.doGet(request, response);
    }
}
