继承Springboot父类，添加xml依赖

配置yml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

注意：

spring:
  application: 
    name: reggie_take_out

这部分可以省略不写，应用的名称默认项目名称，你也可以更改项目名称。

 map-underscore-to-camel-case: true

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 例如user_name--->userName

编写启动类

package com.jkj.reggie;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@Slf4j
@SpringBootApplication
public class ReggieApplication {
    
    public static void main(String[] args) {
    
        SpringApplication.run(ReggieApplication.class,args);
        log.info("项目启动成功！");
    }
}

导入前端页面

把这两个文件直接粘贴在resource下(后续会把资源放到GitHub中，需要自取)

• backend（后端后台功能页面）
• front（前端面板页面）

配置mvc框架的静态资源映射

前端页面没有放到static目录下，配置mvc框架的静态资源映射就是为了加载访问前端页面。

• 在config包下创建MVC拦截器

package com.jkj.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 * @param registry */
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
    
        log.info("开始静态资源映射......");
        registry.addResourceHandler("/backend/**").addResourceLocations("classpath:/backend/");
        registry.addResourceHandler("/front/**").addResourceLocations("classpath:/front/");

    }
}

启动项目

• 报错可以忽略，因为后端还没做。
