Spring batch Eclipse上では動作するがjarからの起動でエラー（UnsatisfiedDependencyException）
Eclipseで実行とかデバッグとかでは正常に動作していたが、maven buildして生成したjarを実行したところ異常終了となった。

原因
すごくしょうもないけどかなり時間がかかってしまった。
結果として、component-scanで読み込んでいたpackageが小文字となっていた。
eclipseでは小文字大文字を判定しない？
原因となったxmlのcomponent-scanタグ
<context:component-scan
base-package="itouoti.batch.Hoge,
itouoti.Hoge,
itouoti.sharedservice,
itouoti.repository.Hoge,
itouoti.repository.sharedRepository,
itouoti.repository.commonDTO" />
「itouoti.sharedService」が正しい
解決策
パッケージの小文字になっているところを大文字にする。
<context:component-scan
base-package="itouoti.batch.Hoge,
itouoti.Hoge,
itouoti.sharedService,
itouoti.repository.Hoge,
itouoti.repository.sharedRepository,
itouoti.repository.commonDTO" />
