Model 層級管理

Domain Model 層的意義

一個傳統 Java Spring 的應用程式會分為三層 @Controller @Service @Repository，然後依據組織需求，再往下細分。 比方說 Service 層複雜的話，會增加 Gateway、Facade 層，或是我們組織獨有的 CoreService 層

另一個層級大部份 Java 組織會忽略的是 Domain Model 層，絕大多數 Java 開發者會開個 entity 或 model package，然後 將所有的 Entity 往裡面丟。然而該 Entity 只是一堆欄位和 getter/setter 的堆疊，也就是單純的 Table 的對應物件而已， 不具備任何 business logic
