public class indexdata {

    public indexdata(String password, String id) {
        this.password = password;
        this.id = id;
    }

    public String getId() {

注册：

    <input name="id" type="text" id="id"><br>

    <label for="password">密码：</label>

@WebServlet("/registe")
public class registe extends HttpServlet {
    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String id = request.getParameter("id");
        String password = request.getParameter("password");
        Dao dao = new Dao();
        try {
            if(dao.registe(id,password,"被评估者")){
                response.sendRedirect("operator.jsp");
            }
            else {
                request.getRequestDispatcher("index.jsp").forward(request, response);
            }
        } catch (SQLException | ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}
填写基本信息表：
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;
import java.sql.Date;
import java.sql.SQLException;

@WebServlet("/addplan")
public class addplan extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String number = request.getParameter("number");
        Date date = Date.valueOf(request.getParameter("date"));
        String reason = request.getParameter("reason");
        plandata data=new plandata(number,date,reason);
        Dao dao=new Dao();
        try {
            if(dao.addplan(data)){
                response.sendRedirect("operator.jsp");
            }
        } catch (SQLException | ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}
对于后续对于老年人及其照护者的功能添加查看评估结果，查看评估表A2被评估者的基本信息，填写A3信息提供者及联系人信息表等功能
