1.創建新項目repo-modele

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

分別創建bs-web，bs-service，bs-entity，bs-mapper四個模塊

3.父模塊核心

4.子模塊引入另外一個子模塊中的類

5.在bs-web項目中創建啟動類

@SpringBootApplication @MapperScan(value = "com.itz") public class Application {public static void main(String[] args) {SpringApplication.run(Application.class);} }
