3.2.3、编写配置文件

server:
  port: 8080

spring: #spring配置
  application:
    name: reggie_take_out     #项目名称
  datasource:     #数据库连接池
    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   #开启日志
    global-config:
      db-config:    #表全局配置
        id-type: ASSIGN_ID    #所有表id使用ASSIGN_ID生成

3.2.4、启动类编写

package com.xxxit.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");
    }
}

3.2.5、导入前端页面

3.2.6、配置SpringMVC配置类设置静态资源映射

package com.xxxit.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;

@Configuration
@Slf4j
public class WebMvcConfig extends WebMvcConfigurationSupport {

    /**
     *
     * @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/");
    }
}
