試した結果
scanBasePackages ={"com.login.controller"}だけだと正常に動作する
scanBasePackages ={"com.login.controller","com.home.controller"}←これだとエラーになる
scanBasePackages ={"com.home.controller"}←これだとエラーになる
interfaceに@serivceをつけてみる×
以上、よろしくお願いします

HomeInterfaceの実装クラスがBean定義されていないのではないでしょうか？
@Autowiredでインジェクトする場合は、少なくとも1つの実装クラスが必要です。
