​url: /employee/delete 实现了员工的删除功能。接收的参数为：id，类型为整数。如果删除成功，跳转到/employee/list, 如果删除失败，则跳转到/error。通过session变量message传递删除成功与失败的消息。根据上面的详细设计，写出EmployeeDeleteServlet的代码(import代码除外)。这是基于Tomecat和javaweb技术所整合的

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

public class EmployeeDeleteServlet extends HttpServlet {

    private static final long serialVersionUID = 1L;

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

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        int id = Integer.parseInt(request.getParameter("id"));
        boolean success = deleteEmployee(id);
        HttpSession session = request.getSession();
        if (success) {
            session.setAttribute("message", "删除成功");
            response.sendRedirect(request.getContextPath() + "/employee/list");
        } else {
            session.setAttribute("message", "删除失败");
            response.sendRedirect(request.getContextPath() + "/error");
        }
    }

    private boolean deleteEmployee(int id) {
        // 在此处实现删除员工的代码
        return true; // 返回删除成功或删除失败的结果
    }

}
