Springboot+MybatisPlus基础搭建

搭建工具及环境：IDEA+Jdk1.8+maven

结合代码生成器篇使用

https://blog.csdn.net/YangChingyuk/article/details/122486935?spm=1001.2014.3001.5502

创建工程

New Project  
	--> Maven
		--> Create from archetype
			--> maven-archetype-quickstart

ps:如果生成的项目工程没有resources目录

main文件下生成resources目录
	New Directory 
		选择 Mark Directory as --> Sources Root

核心pom依赖

application-dev.yml配置文件,放置resources下

server:
	port: 8080

spring:
	application:
		name: springboot-app
	datasource:
		type: com.zaxxer.hikari.HikariDataSource
		driver-class-name: oracle.jdbc.OracleDriver
		url: jdbc:oracle:thin:@host:port:DBName
		username: xxx
		password: xxx

mybatis-plus:
	mapper-locations: classpath:/mapper/xml/*.xml
	configuration:
		log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
		

mapper.xml 放置resources下！

启动类增加注解

@MapperScan({"com.yck.springboot.mapper"})
@SpringBootApplication(scanBasePackages = "com.yck")
public class SpringbootDemoApplication {

	public static void main(String[] args){
		SpringApplication.run(SpringbootDemoApplication .class, args);
	}
}

配置划分：
application.yml

spring:
	profiles:
		active: dev
