瑞吉外卖（1） - Maven项目环境搭建完毕，使用idea上传Gitee正常

Maven项目搭建

新建maven工程

目录与名称

编写启动类

package com.taotao;

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * create by 刘鸿涛
 * 2022/5/25 17:03
 */
@SuppressWarnings({
    
    "all"})
@Slf4j
@SpringBootApplication
public class reggie {
    
    
    public static void main(String[] args) {
    
    
        log.info("项目启动成功");
    }
}

测试通过

导入前端页面

• 直接复制黏贴黑马的资料

backend（后端后台功能页面）

front（前端面板页面）

此时我们虽然已经复制过来了页面，但是启动项目后依然不能正常访问，因为我们没有放在static目录下（静态资源映射）

配置mvc框架的静态资源映射

• 目的就是加载访问前端页面
• 当然你也可以把前端页面放入到static目录下，只是不建议如此而已

新建WebMvcConfig.java

package com.taotao.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;

/**
 * create by 刘鸿涛
 * 2022/5/26 10:17
 */
@SuppressWarnings({
    
    "all"})
//此注解用于记录日志，方便调试
@Slf4j
//Configuration注解说明了这是一个配置类
@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {
    
    
    /**
     * 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/");
    }
}

编写ReggieApplication.java入口

package com.taotao;

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * create by 刘鸿涛
 * 2022/5/25 17:03
 */
@SuppressWarnings({
    
    "all"})
@Slf4j
@SpringBootApplication
public class ReggieApplication {
    
    
    public static void main(String[] args) {
    
    
        SpringApplication.run(ReggieApplication.class,args);
        log.info("项目启动成功");
    }
}

启动测试成功

上传git成功（使用idea上传）
