これは、Spring MVC プロジェクト (3.2.8 RELEASE) の root-context.xml の一部です。
<context:component-scan base-package="org.owls.test">
そして、以下のような構造が得られました。
--org/owls/test
----dao
----dao.impl
----service
----service.impl
----controller
ソース コードに 2 つの注釈を付けました。1 つは@RepositoryDaoImpl クラスにあり、もう1 つは@Serviceサービス インターフェイスにあります。
これを JUnit(4.7) で実行しました。DAOImpl は期待どおりに機能しますが、サービスは機能しません。@Serviceインターフェイスで使用できることはわかっていましたが、どういうわけかこのケースでは使用できません。

私と比較できるように、コンポーネントスキャンxml設定と@Serviceインターフェースの注釈を使用する良いサンプルはありますか?
助けてくれてありがとう:D
