项目开发环境搭建
1.数据库环境搭建
1.1使用Sqlyog创建一个新的数据库
1.2将所使用到的数据表导入到数据库
1.3数据库表解读

2. maven项目搭建
2.1配置父工程pom.xml文件，导入响应的依赖

2.2配置application.yml
server:
port: 8080
spring:
application:
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
2.3创建启动类，启动项目
package com.jq.rj;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@Slf4j
@SpringBootApplication
public class RJApplication {
public static void main(String[] args) {
SpringApplication.run(RJApplication.class, args);
log.info("项目启动成功");
}
}
2.4导入前端页面
2.4.1页面目录介绍
- 后台页面
- 移动端页面
2.4.2编写配置类，映射静态资源
上述资源是放在 resource目录下的，直接访问不到，需要进行配置类编写进行映射
package com.jq.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;
/**
* 配置类，映射静态资源
*/
@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("开始进行静态资源映射...");
registry.addResourceHandler("/backend/**").addResourceLocations("classpath:/backend/");
registry.addResourceHandler("/front/**").addResourceLocations("classpath:/front/");
}
}
2.4.3 错误
如果加载资源错误，检查一下自己的路径是否正确，application启动类放置的位置是否正确，整个项目的名称是否一致，jdk版本，maven版本
