springboot+maven实现模块化编程

1.创建新项目repo-modele

2.右键Repo_modele -> New -> Module…->next

分别创建bs-web，bs-service，bs-entity，bs-mapper四个模块

3.父模块核心

            </plugin>

        </plugins>

    </build>

</project>

4.子模块引入另外一个子模块中的类

5.在bs-web项目中创建启动类

@SpringBootApplication

@MapperScan(value = "com.itz")

public class Application {

    public static void main(String[] args) {

        SpringApplication.run(Application.class);

    }

}

6.application.yaml

server:

  port: 8080

spring:

  datasource:

    driver-class-name: com.mysql.cj.jdbc.Driver

    username: root

    password: hao20001010

    url: jdbc:mysql:localhost:3306/crud?serverTimezone=UTC

mybatis:

  mapper-locations: mapper/*.xml

  type-aliases-package: com.itz

  configuration:

    map-underscore-to-camel-case: true

    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
