3.2 pen left sco 定義 project localhost pack view
1. 新建maven項目springboot-module
2.把src刪掉，新建module項目
-
springboot-module-api
-
springboot-module-model
-
springboot-module-service
-
springboot-module-util
-
springboot-module-web
3. 添加模塊之間的依賴

4. 模塊依賴關系圖
5. 層說明
springboot-module-api ——業務邏輯接口
springboot-module-model ——實體類
springboot-module-service ——數據訪問層，業務邏輯層的實現
springboot-module-util ——工具模塊
springboot-module-web ——表現層
6. 包名設計
包名推薦以groupId為開頭定義，所有模塊的包名結構統一規範，比如groupId是com.springboot.module,而所有模塊包名都以com.springboot.module開頭，其中web層的WebApplication需要放在com.springboot.module下，不能放在com.springboot.module.web或者com.springboot.module.controller下。推薦使用下面的第一種情況。
6.1. 包名以groupId開頭，註意WebApplication.java的位置，必須放在com.springboot.module包下，不能放在com.springboot.module.controller或者com.springboot.module.web包下
6.2. 包名以groupId開頭，web層WebApplication.java放在了com.springboot.module.web下。
啟動WebApplication.java會報如下錯誤
6.2.1. 解決方法：
1) 第一步：在WebApplication中加入
1 @ComponentScan(basePackages = {"com.springboot.module"})不是@ComponentScan(basePackages = {"com.springboot.module.*"})
1) 第二步，在springboot-module-service模塊中添加ServiceApplication.java類，
6.2.2. 包名不以groupId開頭，其他和第一種情況一樣也是可以的。但最好推薦是以groupId為開頭的
7.只有 web層有application.properties
1 server.port=8086 2 server.servlet-path=/ 3 spring.resources.static-locations=classpath:/static/,classpath:/templates/ 4 spring.mvc.view.suffix=.html 5 6 #配置數據源 7 spring.datasource.driver-class-name=com.mysql.jdbc.Driver 8 spring.datasource.url=jdbc:mysql://localhost:3306/springboot-module 9 spring.datasource.username=root 10 spring.datasource.password=root 11 spring.jpa.hibernate.ddl-auto=update 12 spring.jpa.show-sql=true 13 14 #在控制臺輸出彩色日誌 15 spring.output.ansi.enabled=always
