  1. Servlet 层（控制层 + 权限校验）
    （1）LoginServlet.java（统一登录入口）
    java
    运行
    package com.company.detection.controller;

import com.company.detection.entity.User;
import com.company.detection.service.UserService;
import com.company.detection.service.impl.UserServiceImpl;

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 javax.servlet.http.HttpSession;
import java.io.IOException;

@WebServlet("/login")
public class LoginServlet extends HttpServlet {
private UserService userService = new UserServiceImpl();

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    request.setCharacterEncoding("UTF-8");
    String userId = request.getParameter("userId");
    String userPwd = request.getParameter("userPwd");

    // 登录验证
    User user = userService.login(userId, userPwd);
    if (user == null) {
        request.setAttribute("errorMsg", "账号或密码错误！");
        request.getRequestDispatcher("/login.jsp").forward(request, response);
        return;
    }

    // 存储登录状态，按角色跳转
    HttpSession session = request.getSession();
    session.setAttribute("loginUser", user);
    int category = user.getUserCategory();
    if (category == 0) { // 检测员
        response.sendRedirect(request.getContextPath() + "/inspector/index.jsp");
    } else if (category == 1) { // 项目经理
        response.sendRedirect(request.getContextPath() + "/manager/index.jsp");
