Spring Boot 2 starter

背景
Spring boot解決すべき問題1、配置自動化2、マイクロサービス
includeモジュール

at configureモジュールは、自動構成コード

を含む.

starterモジュールはaut configurに依存を提供し、関連jarの依存性でもある

.
at configurとstarterのコードは一緒に書くことができます.
名前を付ける
例えば私が作成したいstarterの名前はsmsです.それではatoconfigurとstarterの名前はそれぞれです.

sms-spring-boot-at configre

sms-spring-boot-starter

at configureモジュール
必要なlibrary、propertiesの中のkey(@ConfigrationProptiesによって構成されています)と初期化しなければならないいくつかのコンテナ(例えば、mybatisはdata Sourceを初期化しなければなりません)を含んでいます.
スターターモジュール
は、いくつかの必要な依存を提供するために空のjarです.
