页面原型
1. 登录页面展示：项目路径（\resources\backend\page\login\login.html）
员工点击登录按钮进行后管平台的登录操作，登录正确以外方式不可登录。

// 根据用户名查数据库

queryWrapper.eq(Employee::getUsername, employee.getUsername());
Employee emp = employeeService.getOne(queryWrapper);
// 查不到返回登录失败结果
if(emp == null){
return R.error(CommonsConst.LOGIN_FAIL);
}
// 比对密码
if(!emp.getPassword().equals(password)){
return R.error(CommonsConst.LOGIN_FAIL);
}
// 查看员工状态
if(emp.getStatus() == CommonsConst.EMPLOYEE_STATUS_NO){
return R.error(CommonsConst.LOGIN_ACCOUNT_STOP);
}
// 登录成功将员工的ID放入session中
request.getSession().setAttribute("employeeId",emp.getId());
return R.success(emp);
}
}Debug测试时主要测试以下几点：
常量类：
package com.itheima.reggie.common;
/**
* 常量定义
* @author jektong
* @date 2022/4/23
*/
public class CommonsConst {
// 登录失败
public static final String LOGIN_FAIL = "登录失败";
// 账号禁用
public static final String LOGIN_ACCOUNT_STOP = "账号禁止使用";
// 员工账号禁用状态 0：禁用
public static final Integer EMPLOYEE_STATUS_NO = 0;
// 员工账号正常状态 1：正常使用
public static final Integer EMPLOYEE_STATUS_YES = 1;
}
