    一、SpringBoot项目简介

    1、技术点介绍

    2、数据表介绍

    二、构建SpringBoot项目

    1.创建SpringBoot项目并配置POM

    2.配置application.yml

    3.启动类配置

    4.首页访问 ,导入前端页面及页面对应的js/css/images文件

    三、实现首页功能

    0）导入帮助类

    config：

    exception:

    Generator：

    Utils：

    在generater类运行自动生成代码：

    1）创建公共跳转控制器PageController

    2）使用Mybatis-plus反向生成代码(Goods商品信息)

    3）创建IndexController并定义商品查询请求处理方法

    四、用户明文登录

    创建UserController类实现用户登录

            1.1）构建UserDto，定义mobile和password属性

            1.2）创建UserController类

            1.3）定义userLogin(UserDto userDto,HttpServletRequest req,HttpServletResponse resp)

            1.4）定义响应封装类JsonResponseBody和JsonResponseStatus

            1.5）在IUserService中定义userLogin(UserVo userVo)，并返回JsonResponseBody

            1.6）全局异常处理

            1.7）自定义注解参数校验（JSR303）

    login.js:

    测试多种情况: 

    五、前端及数据库密码加密

    UserServiceImpl.java变更如下

    login.js变更如下:

    六、服务端客户端登录密码管理

    UserServiceImpl.java变更如下

    一、SpringBoot项目简介

    1、技术点介绍

    前端：Freemarker、jQuery
    后端：SpringBoot、MyBatisPlus、Lombok
    中间件：Redis

    2、数据表介绍

    用户表：t_user

    商品表：t_goods

    订单表：t_order

    订单项表：t_order_item

    数据源表：t_dict_type

    数据项表：t_dict_data

    后续微服务秒杀项目所用：
    秒杀商品表：t_seckill_goods
    秒杀订单表：t_seckill_order

    二、构建SpringBoot项目

    起初搭建时，可以不勾选任何组件

    1.创建SpringBoot项目并配置POM

     在generater类运行自动生成代码：

    在控制台输入表名：

    生成成功：

    1）创建公共跳转控制器PageController

    1. package com.ycx.spbootpro.controller;
    2.  
    3. import org.springframework.stereotype.Controller;
    4. import org.springframework.web.bind.annotation.PathVariable;
    5. import org.springframework.web.bind.annotation.RequestMapping;
    6.  
    7. /**

    24.     }
    25.  
    26.     /**

    33.                       @PathVariable(value = "page") String page) {
    34.         return dir + "/" + page;

    3）创建IndexController并定义商品查询请求处理方法

    1. package com.ycx.spbootpro.controller;
    2.  
    3. import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
    4. import com.ycx.spbootpro.model.Goods;
    5. import com.ycx.spbootpro.service.IGoodsService;
    6. import com.ycx.spbootpro.utils.DataUtils;
    7. import org.springframework.beans.factory.annotation.Autowired;
    8. import org.springframework.stereotype.Controller;
    9. import org.springframework.ui.Model;
    10. import org.springframework.web.bind.annotation.RequestMapping;
    11.  
    12. import java.util.List;
    13. import java.util.Map;
    14.  
    15. /**
    16.  * @author 杨总
    17.  * @create 2022-11-04 21:02
    18.  */
    19. @Controller
    20. public class IndexController {
    21.     @Autowired
    22.     private IGoodsService goodsService;
    23.  
    24.  
    25.     @RequestMapping("/")
    26.     public String index(Model model){
    27.         //  摆件花艺
    28.         List<Goods> goods01 = goodsService.list(new QueryWrapper<Goods>()
    29.                 .eq("goods_type", "01")
    30.                 .last("limit 6"));
    31.  
    32.         //  壁挂北欧
    33.         List<Goods> goods07 = goodsService.list(new QueryWrapper<Goods>()
    34.                 .eq("goods_type", "07")
    35.                 .last("limit 12"));
    36.  
    37. //        为了方便首页数据显示，方便摆放
    38.         DataUtils<Goods> dataUtils = new DataUtils<>();
    39.         Map<String, List<Goods>> gt01 = dataUtils.transfor(3, goods01);
    40.         Map<String, List<Goods>> gt07 = dataUtils.transfor(4, goods07);
    41.         model.addAttribute("gt01",gt01);
    42.         model.addAttribute("gt07",gt07);
    43.         return "index.html";
    44.     }
    45.  
    46. }

    首页数据绑定语法:

    1) list集合判空
    <#if goods07?? && goods07?size gt 0>

    2) 遍历map集合，获取所有的keys
    <#list goods07?keys as key>

    3) 根据key获取对应value值goods01[key]
    <#list goods07[key] as g>

    运行： 

     

    四、用户明文登录

    创建UserController类实现用户登录

            1.1）构建UserDto，定义mobile和password属性

            定义UserDto.java接受前台传递的参数：

    1. package com.ycx.spbootpro.model.dto;
    2.  
    3. import com.ycx.spbootpro.validator.IsMobile;
    4. import lombok.Data;
    5.  
    6. import javax.validation.constraints.NotBlank;
    7.  
    8. @Data
    9. public class UserDto {
    10.     @NotBlank(message = "手机号码不能为空！")
    11.     @IsMobile
    12.     private String mobile;
    13.     @NotBlank(message = "密码不能为空！")
    14.     private String password;
    15. }

            


            1.2）创建UserController类

    处理浏览器端的请求 UserController.java

    1. package com.ycx.spbootpro.controller;
    2.  
    3.  
    4. import com.ycx.spbootpro.model.dto.UserDto;
    5. import com.ycx.spbootpro.service.IUserService;
    6. import com.ycx.spbootpro.utils.JsonResponseBody;
    7. import org.springframework.beans.factory.annotation.Autowired;
    8. import org.springframework.web.bind.annotation.RequestMapping;
    9.  
    10. import org.springframework.web.bind.annotation.RestController;
    11.  
    12. import javax.servlet.http.HttpServletRequest;
    13. import javax.servlet.http.HttpServletResponse;
    14. import javax.validation.Valid;
    15.  
    16. /**
    17.  * 
    18.  * 用户信息表 前端控制器
    19.  * 
    20.  *
    21.  * @author yangzong
    22.  * @since 2022-11-05
    23.  */
    24. @RestController
    25. @RequestMapping("/user")
    26. public class UserController {
    27.  
    28.     @Autowired
    29.     private IUserService userService;
    30.  
    31.     @RequestMapping("/toLogin")
    32.     public JsonResponseBody toLogin(@Valid UserDto userDto,
    33.                                     HttpServletRequest req,
    34.                                     HttpServletResponse resp){
    35.  
    36.         return userService.toLogin(userDto,req,resp);
    37.     }
    38. }


            1.3）定义userLogin(UserDto userDto,HttpServletRequest req,HttpServletResponse resp)


            1.4）定义响应封装类JsonResponseBody和JsonResponseStatus

            1.5）在IUserService中定义userLogin(UserVo userVo)，并返回JsonResponseBody

    1.5.1）判断mobile和password是否为空
    1.5.2）判断mobile格式是否正确
    1.5.3）根据用户手机号码查询用户是否存在
    1.5.4）校验账号
    1.5.5）校验密码

    1. package com.ycx.spbootpro.service.impl;
    2.  
    3. import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
    4. import com.ycx.spbootpro.exception.BusinessException;
    5. import com.ycx.spbootpro.model.User;
    6. import com.ycx.spbootpro.mapper.UserMapper;
    7. import com.ycx.spbootpro.model.dto.UserDto;
    8. import com.ycx.spbootpro.service.IUserService;
    9. import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
    10. import com.ycx.spbootpro.utils.JsonResponseBody;
    11. import com.ycx.spbootpro.utils.JsonResponseStatus;
    12. import org.springframework.beans.factory.annotation.Autowired;
    13. import org.springframework.stereotype.Service;
    14.  
    15. import javax.servlet.http.HttpServletRequest;
    16. import javax.servlet.http.HttpServletResponse;
    17. import javax.validation.Valid;
    18.  
    19. /**

    24.  * @author yangzong
    25.  * @since 2022-11-05
    26.  */
    27. @Service
    28. public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements IUserService {
    29.     @Autowired
    30.     private UserMapper userMapper;
    31.  
    32.     @Override
    33.     public JsonResponseBody toLogin(UserDto userDto, HttpServletRequest req, HttpServletResponse resp) {
    34. //        1.5.1）判断mobile和password是否为空(已由JSP303完成）
    35. //        1.5.2）判断mobile格式是否正确（自定义验证注解）
    36. //        1.5.3）根据用户手机号码查询用户是否存在
    37.         User user = userMapper.selectOne(new QueryWrapper<User>()
    38.                 .eq("id", userDto.getMobile()));
    39.  
    40.         //1.5.4）校验账号
    41.         //判断用户对象是否存在
    42.         if(null==user)
    43.             throw new BusinessException(JsonResponseStatus.USER_USERNAME_ERROR);
    44.  
    45.  
    46. //        1.5.5）校验密码
    47.         if(!user.getPassword().equals(userDto.getPassword()))
    48.             throw new BusinessException(JsonResponseStatus.USER_PASSWORD_ERROR);
    49.       
    50.         return new JsonResponseBody<>();
    51.     }
    52.  
    53. }

            1.6）全局异常处理

    1.6.1）创建BusinessException
    1.6.2）创建GlobalExceptionHandler
    1.6.3）修改userLogin中的异常处理方式

            1.7）自定义注解参数校验（JSR303）

    1.7.1）创建自定义注解IsMobile
    1.7.2）创建自定义校验规则类MobileValidator
    1.7.3）在UserVo类的mobile属性中使用IsMobile注解

            自定义JSR303注解，完成服务端登录账号的验证

    查看用户表数据

    login.js:

    1. $(function () {
    2.     alert(2);
    3.  
    4.     //登录向后台发送Ajax请求
    5.    $("#login").click(function () {
    6.        let mobile = $("#mobile").val();
    7.        let password = $("#password").val();
    8.  
    9.  
    10.        $.post("/user/toLogin",{
    11.            mobile:mobile,
    12.            password:password
    13.        },function (res) {
    14.            alert(res.msg)
    15.        },"json");
    16.    })
    17. });

    测试多种情况: 

    1.手机号为空

    2.手机号为非法字符

    3.密码为空

    4.手机号不存在

    5.手机号密码正确

    6.密码错误

    五、前端及数据库密码加密

    前端加密：防止客户端浏览器F12导致密码泄露

    后端加密：防止数据库数据泄露导致密码泄露

    运行：

    把 后端加密随机盐 和 加密密码  复制进表数据：

     

     再次运行，每次运行出来的密码都不一样：

    记得在login.html导入：
