瑞吉外卖笔记-基本功能篇

第一章：概述-项目介绍

1. 软件开发整体介绍

2. 瑞吉外卖项目介绍

3. 开发环境搭建

新建好以后，编辑pom文件

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

接着copy好application.yml配置文件

server:
  port: 8080
spring:
  application:
    #应用的名称，可选
    name: reggie_take_out
  datasource:
    druid:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/reggie?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true
      username: root
      password: root
mybatis-plus:
  configuration:
    #在映射实体或者属性时，将数据库中表名和字段名中的下划线去掉，按照驼峰命名法映射
    map-underscore-to-camel-case: true
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
  global-config:
    db-config:
      id-type: ASSIGN_ID

将项目的前端文件copy到resources文件夹下

接着要配置静态资源映射，目的是将浏览器访问到的内容映射到实际目录中的文件
新建文件com.reggie.config.WebMvcConfig

package com.itheima.reggie.config;


import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

@Slf4j
@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {
    
    
    /**
     * 设置静态资源映射
     * 作用：浏览器访问到的内容映射到实际目录中的文件
     * @param registry
     */
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
    
    
        log.info("开始进行静态资源映射...");
        registry.addResourceHandler("/backend/**").addResourceLocations("classpath:/backend/");
        registry.addResourceHandler("/front/**").addResourceLocations("classpath:/front/");
    }
}

4. 后台系统登录功能
