# 概述 #

通过对三张表的CRUD，将相应的操作结果渲染到页面上。  
如果想查看SSM架构的同等规模的项目，可参考此篇博客[SSM项目实例——简易版图书管理系统][SSM]  
为了更好地讲解整个项目，与上篇博客不同的是，我将代码的实现部分分为**后台部分**和**前台部分**，作为一个更好的区分。  
在讲解中，若在标题中标示出“**扩展**”，即该部分是项目的拓展部分，如果想要运行整个项目也可以不进行添加，这里根据需求使用即可。  
末尾的后记部分有源码地址，读者可参考。

# 实现 #

## 后台部分 ##

### 1.搭建数据库 ###

1.  创建一个存放数据的数据库（smms），并在该数据库中建立三张表：user（用户）、orders（订单）、goods（商品），并且添加一些数据，其中需要特别说明的是，orders表中的`order_userid`作为user表中`user_id`的外键字段，goods表中的`goods_id`作为orders表中的`order_id`的外键字段，代码如下：

-- MySQL dump 10.13 Distrib 5.7.19, for Win64 (x86_64)
    --
    -- Host: 127.0.0.1 Database: smms

    INSERT INTO `orders` VALUES (14,'莫息涛','2020-03-02',11);
    /*!40000 ALTER TABLE `orders` ENABLE KEYS */;
    UNLOCK TABLES;
    
    --

1.  保证IDEA中可以连接到MySql，并且在Database预览卡中能够查看其中的数据，如图所示：  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxMTUxNjU5_size_16_color_FFFFFF_t_70 1]

### 2.依赖管理 ###

通过IDEA新建一个Spring Boot项目，然后再pom.xml文件中导入相应的依赖，代码如下：

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

                </plugin>
            </plugins>
        </build>
    
    </project>

### 3.配置文件 ###

修改resouces目录下的application.properties/application.yaml，这里选用yaml格式的配置文件，首先配置数据源，然后禁用thymeleaf模板引擎中的缓存，最后再配置mybatis的实体类映射路径以及mapper的存放路径，其中所有的路径可以根据实际的项目需要来进行修改，代码如下：

spring:
      datasource:
        username: root
        password: 123456
        url: jdbc:mysql://localhost:3306/smms?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
        driver-class-name: com.mysql.cj.jdbc.Driver
      thymeleaf:
        cache: false
    mybatis:
      mapper-locations: classpath:mappers/*.xml
      type-aliases-package: com.project.smms.pojo

### 4.实现pojo层 ###

1.  在项目的包下新建一个pojo包，用于存放实体类，并在其中新增User类，对应数据库中的user表，代码如下：

package com.project.smms.pojo;
    
    /** * @author 莫息涛 * @Description: 用户的实体类 * @date 2020/3/5 16:09 */
    public class User { 
    
        /** * 用户id */
        private int user_id;
    
        /** * 用户名 */
        private String user_name;
    
        /** * 用户密码 */
        private String user_passwd;
    
        /** * 用户是否是管理员，1代表是，0代表否 */
        private int user_ismanager;
    
        public User() { 
        }
    
        public User(int user_id, String user_name, String user_passwd, int user_ismanager) { 
            this.user_id = user_id;
            this.user_name = user_name;
            this.user_passwd = user_passwd;
            this.user_ismanager = user_ismanager;
        }
    
        public int getUser_id() { 
            return user_id;
        }
    
        public void setUser_id(int user_id) { 
            this.user_id = user_id;
        }
    
        public String getUser_name() { 
            return user_name;
        }
    
        public void setUser_name(String user_name) { 
            this.user_name = user_name;
        }
    
        public String getUser_passwd() { 
            return user_passwd;
        }
    
        public void setUser_passwd(String user_passwd) { 
            this.user_passwd = user_passwd;
        }
    
        public int getUser_ismanager() { 
            return user_ismanager;
        }
    
        public void setUser_ismanager(int user_ismanager) { 
            this.user_ismanager = user_ismanager;
        }
    
        @Override
        public String toString() { 
            return "User{" +
                    "user_id=" + user_id +
                    ", user_name='" + user_name + '\'' +
                    ", user_passwd='" + user_passwd + '\'' +
                    ", user_ismanager=" + user_ismanager +
                    '}';
        }
    }

1.  在pojo包中新增Order类，对应数据库中的orders表，代码如下：

package com.project.smms.pojo;
    
    import org.springframework.format.annotation.DateTimeFormat;
    
    import java.util.Date;
    
    /** * @author 莫息涛 * @Description: 订单的实体类 * @date 2020/3/5 16:08 */
    public class Order { 
    
        /** * 订单id */
        private int order_id;
    
        /** * 订单名称 */
        private String order_name;
    
        /** * 订单日期 */
        @DateTimeFormat(pattern="yyyy-MM-dd")
        private Date order_date;
    
        /** * 订单的用户id */
        private int order_userid;
    
        public Order() { 
        }
    
        public Order(int order_id, String order_name, Date order_date, int order_userid) { 
            this.order_id = order_id;
            this.order_name = order_name;
            this.order_date = order_date;
            this.order_userid = order_userid;
        }
    
        public int getOrder_id() { 
            return order_id;
        }
    
        public void setOrder_id(int order_id) { 
            this.order_id = order_id;
        }
    
        public String getOrder_name() { 
            return order_name;
        }
    
        public void setOrder_name(String order_name) { 
            this.order_name = order_name;
        }
    
        public Date getOrder_date() { 
            return order_date;
        }
    
        public void setOrder_date(Date order_date) { 
            this.order_date = order_date;
        }
    
        public int getOrder_userid() { 
            return order_userid;
        }
    
        public void setOrder_userid(int order_userid) { 
            this.order_userid = order_userid;
        }
    
        @Override
        public String toString() { 
            return "Order{" +
                    "order_id=" + order_id +
                    ", order_name='" + order_name + '\'' +
                    ", order_date=" + order_date +
                    ", order_userid=" + order_userid +
                    '}';
        }
    }

1.  在pojo包中新增Goods类，对应数据库中的goods表，代码如下：

package com.project.smms.pojo;
    
    import org.springframework.stereotype.Component;
    
    /** * @author 莫息涛 * @Description: 商品的实体类 * @date 2020/3/5 15:55 */
    @Component
    public class Goods { 
    
        /** * 商品id */
        private int goods_id;
    
        /** * 商品名 */
        private String goods_name;
    
        /** * 商品描述 */
        private String goods_description;
    
        /** * 商品数量 */
        private int goods_count;
    
        /** * 商品的订单id */
        private int goods_orderid;
    
        public Goods() { 
        }
    
        public Goods(int goods_id, String goods_name, String goods_description, int goods_count, int goods_orderid) { 
            this.goods_id = goods_id;
            this.goods_name = goods_name;
            this.goods_description = goods_description;
            this.goods_count = goods_count;
            this.goods_orderid = goods_orderid;
        }
    
        public int getGoods_id() { 
            return goods_id;
        }
    
        public void setGoods_id(int goods_id) { 
            this.goods_id = goods_id;

    import com.project.smms.pojo.User;
    
    import java.util.List;
    
    /** * @author 莫息涛 * @Description: 用户的服务层接口 * @date 2020/3/5 16:30 */
    public interface UserService { 
    
        /** * 查询所有用户 * @return */
        List<User> selectUser();
    
        /** * 根据id查询用户 * @param user_id * @return */
        User selectUserById(int user_id);
    
        /** * 添加一个用户 * @param user * @return */

            return userMapper.updateUser(user);
        }
    
        @Override
        public int deleteUser(int user_id) { 
            return userMapper.deleteUser(user_id);
        }
    }

        }
    
        @Override
        public Order selectOrderById(int order_id) { 
            return orderMapper.selectOrderById(order_id);
        }
    
        @Override
        public int addOrder(Order order) { 
            return orderMapper.addOrder(order);

            }catch (Exception e){ 
                return "errordata";
            }finally { 
                Collection<Order> orders = orderService.selectOrder();
                model.addAttribute("orders",orders);
            }
            return "order";
        }
    
        @RequestMapping("/toAddOrderPage")
        public String toAddPage(Model model){ 
            List<User> users = userService.selectUser();
            model.addAttribute("ordersuser",users);
            return "addorder";
        }
    
        @RequestMapping("/addOrder")
        public String addOrder(Order order, Model model){ 
            try { 
                orderService.addOrder(order);
            }catch (Exception e){ 
                return "errordata";
            }finally { 
                Collection<Order> orders = orderService.selectOrder();
                model.addAttribute("orders",orders);
            }
            return "order";
        }
    
        @RequestMapping("/toUpdateOrderPage/{order_id}")
        public String toUpdatePage(@PathVariable("order_id") Integer id,Model model){ 
            Order order = orderService.selectOrderById(id);
            List<User> users = userService.selectUser();
            model.addAttribute("ordersuser",users);
            model.addAttribute("updateorder",order);
            return "updateorder";
        }
    
        @RequestMapping("/updateOrder")
        public String updateOrder(Order order, Model model){ 
            try { 
                orderService.updateOrder(order);
            }catch (Exception e){ 
                return "errordata";
            }finally { 
                Collection<Order> orders = orderService.selectOrder();
                model.addAttribute("orders",orders);
            }
            return "order";
        }
    }

1.  在controller下新增GoodsController，代码如下：

package com.project.smms.controller;
    
    import com.project.smms.pojo.Goods;
    import com.project.smms.pojo.Order;
    import com.project.smms.service.GoodsService;
    import com.project.smms.service.OrderService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import java.util.Collection;
    import java.util.List;
    
    /** * @author 莫息涛 * @Description: 商品的控制层 * @date 2020/3/7 15:11 */
    @Controller
    public class GoodsController { 
    
        @Autowired
        private OrderService orderService;
    
        @Autowired
        private GoodsService goodsService;
    
        @RequestMapping("/selectGoods")
        public String selectGoods(Model model){ 
            Collection<Goods> goods = goodsService.selectGoods();
            model.addAttribute("goods",goods);
            return "goods";
        }
    
        @RequestMapping("/deleteGoods/{goods_id}")
        public String deleteGoods(@PathVariable("goods_id") Integer id, Model model){ 
            try { 
                goodsService.deleteGoods(id);
            }catch (Exception e){ 
                return "errordata";
            }finally { 
                Collection<Goods> goods = goodsService.selectGoods();
                model.addAttribute("goods",goods);
            }
            return "goods";
        }
    
        @RequestMapping("/toAddGoodsPage")
        public String toAddPage(Model model){ 
            List<Order> order = orderService.selectOrder();
            model.addAttribute("ordergoods",order);
            return "addgoods";
        }
    
        @RequestMapping("/addGoods")
        public String addGoods(Goods goods, Model model){ 
            try { 
                goodsService.addGoods(goods);
            }catch (Exception e){ 
                return "errordata";
            }finally { 
                Collection<Goods> goods1 = goodsService.selectGoods();
                model.addAttribute("goods",goods1);
            }
            return "goods";
        }
    
        @RequestMapping("/toUpdateGoodsPage/{goods_id}")
        public String toUpdatePage(@PathVariable("goods_id") Integer id,Model model){ 
            List<Order> order = orderService.selectOrder();
            Goods goods = goodsService.selectGoodsById(id);
            model.addAttribute("ordergoods",order);
            model.addAttribute("updategoods",goods);
            return "updategoods";
        }
    
        @RequestMapping("/updateGoods")
        public String updateGoods(Goods goods, Model model){ 
            try { 
                goodsService.updateGoods(goods);
            }catch (Exception e){ 
                return "errordata";
            }finally { 
                Collection<Goods> goods1 = goodsService.selectGoods();
                model.addAttribute("goods",goods1);
            }
            return "goods";
        }
    }

### 8.实现component层（拓展） ###

在项目的包下新建一个component包，用于存放项目中用到的各种组件，并在其中新增LoginInterceptor，用于作为一个验证登录的拦截器，代码如下：

package com.project.smms.component;
    
    import com.project.smms.pojo.User;
    import org.springframework.stereotype.Component;
    import org.springframework.web.servlet.HandlerInterceptor;
    import org.springframework.web.servlet.ModelAndView;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import javax.servlet.http.HttpSession;
    
    /** * @author 莫息涛 * @Description: 登录相关的拦截器 * @date 2020/3/11 16:35 */
    @Component
        public class LoginInterceptor implements HandlerInterceptor { 
        @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { 
            HttpSession session = request.getSession();
            User user = (User) session.getAttribute("user");
            if (user == null){ 
                return false;
            }else { 
                return true;
            }
        }
    
        @Override
        public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { 
    
        }
    
        @Override
        public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception { 
    
        }
    }

### 9.实现config层（拓展） ###

在项目的包下新建一个config包，用于存放项目中用到的一些配置文件，并在其中新增InterceptorConfig，用于作为一个拦截器的配置文件，代码如下：

package com.project.smms.config;
    
    import com.project.smms.component.LoginInterceptor;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
    
    /** * @author 莫息涛 * @Description: 登录相关的拦截器的配置类 * @date 2020/3/11 16:35 */
    @Configuration
    public class InterceptorConfig implements WebMvcConfigurer { 
    
        @Override
        public void addInterceptors(InterceptorRegistry registry) { 
            registry.addInterceptor(new LoginInterceptor())
            .excludePathPatterns("/toLogin","/checkUser","/toLogin/","/checkUser/","/**/*.css","/**/*.js");
        }
    }

### 10.实现utils层（拓展） ###

1.  在项目的包下新建一个utils包，用于存放项目中用到的一些工具类，并在其中新增LogLevel，用于作为日志工具类的日志等级控制，代码如下：

package com.project.smms.utils.log;
    
    /** * <pre> * 日志级别 * ALL("全部", 0) * INFO("信息", 1) * WARN("警告", 2) * ERROR("错误", 3) * </pre> * * @since 2018年4月9日 9:31:46 * @author ygr */
    public enum LogLevel { 
        ALL("[]", 0), INFO("[INFO]", 1), WARN("[WARN]", 2), ERROR("[ERROR]", 3);
    
        private String name;
        private int level;
    
        LogLevel(String name, int level) { 
            this.name = name;
            this.level = level;
        }
    
        public String getName() { 
            return name;
        }
    
        public int getLevel() { 
            return level;
        }
        /** * <pre> * 判断是否允许打印 * </pre> * @author ygr * @date 2018年4月9日 上午9:36:47 * @param minLevel 最低日志级别 * @return */
        public boolean isAllow(LogLevel minLevel){ 
            if(level >= minLevel.getLevel()){ 
                return true;
            }
    
            return false;
        }
    }

1.  在utils下新增LogUtils，作为日志输出的工具类，代码如下：

package com.project.smms.utils.log;
    
    import java.text.SimpleDateFormat;
    import java.util.Date;
    
    /** * <pre> * 简单的日志工具类 * </pre> * * @since 2018年4月9日 上午9:30:12 * @author ygr */
    public class LogUtils { 
        /** 默认可以打印 */
        private static boolean enable = true;
        /** 默认打印所有级别日志 */
        private static LogLevel minLevel = LogLevel.ALL;
        /** 日期显示格式 */
        private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-mm-dd HH:mm:ss");
    
        /** * <pre> * 设置是否开启打印 * </pre> * * @author ygr * @date 2018年4月9日 上午9:54:46 * @param enable */
        public static void setEnable(boolean enable) { 
            LogUtils.enable = enable;
        }
        /** * <pre> * 设置日志打印级别 * </pre> * * @author ygr * @date 2018年4月9日 上午9:42:09 * @param level */
        public static void setLogLevel(LogLevel level) { 
            LogUtils.minLevel = level;
        }
    
        /** * <pre> * 打印消息级别日志 * </pre> * * @author ygr * @date 2018年4月9日 上午9:42:59 * @param msg * 待打印消息 */
        public static void info(String msg) { 
            finalPrint(LogLevel.INFO, msg);
        }
    
        /** * <pre> * 打印警告级别日志 * </pre> * * @author ygr * @date 2018年4月9日 上午9:42:59 * @param msg * 待打印消息 */
        public static void warn(String msg) { 
            finalPrint(LogLevel.WARN, msg);
        }
    
        /** * <pre> * 打印错误级别日志 * </pre> * * @author ygr * @date 2018年4月9日 上午9:42:59 * @param msg * 待打印消息 */
        public static void error(String msg) { 
            finalPrint(LogLevel.ERROR, msg);
        }
    
        /** * <pre> * 最终打印日志 * </pre> * * @author ygr * @date 2018年4月9日 上午9:50:21 * @param logLevel * 日志级别 * @param msg * 待打印消息 */
        private static void finalPrint(LogLevel logLevel, String msg) { 
            if (!enable) { 
                return;
            }
            if (logLevel.isAllow(minLevel)) { 
                System.out.printf("%s %s %s\n", formatCurrentTime(), logLevel.getName(), msg);
            }
        }
    
        /** * <pre> * 获取当前时间 * </pre> * * @author ygr * @date 2018年4月9日 上午9:49:00 * @return */
        private static String formatCurrentTime() { 
            return sdf.format(new Date());
        }
    }

## 前台部分 ##

### 1.引入BootStrap和JQuery ###

由于在项目里用到了BootStrap和JQuery，这里需要将它们引入到项目中，Spring Boot使用resources/static目录来存放静态文件，我们将这两个框架导到这里，如图所示：  
![在这里插入图片描述][20200325161550393.png]

### 2.实现View层 ###

由于View层页面较多，这里进行一个细致的划分，以此来更好地陈列这些页面

#### 1.登录页面 login.html ####

# 运行 #

配置好Tomcat运行环境后，运行启动类，即可开始运行，结果图如下：

1.  调用/toLogin请求，访问登录页面，如图所示：

# 后记 #

耽搁了一个月才开始更新博客，属实是最近有些懒惰了，实在抱歉。近期也在准备春招的事情，待我整理完后，将会把春招的面经更新到博客上。  
相比于SSM，Spring Boot的明显优点在于配置文件的简化，以及可以使用独特的Thymeleaf模板引擎来支持使用html代码，通过restful调用，就可以快速而高效地搭建出一个Web项目。当然，编程的思想才应该是我们注重的关键，有了编程的思想，无论使用什么框架都能够很快地了解其思想，并且进行正确地调用。  
如果读者在浏览该博客时遇到什么问题，可以及时联系我，或者在留言区留下问题，我在看到后会第一时间回复，感谢您的浏览！
