原因
<bean class="org.springframework.batch.core.configuration.support.JobRegistryBeanPostProcessor" p:jobRegistry-ref="jobRegistry"/>
の競合が発生していた。
具体的には別々のxmlにある同じ設定を一緒に読み込んでしまったことで、設定が競合しエラーが発生した。
解決策
xmlの競合している設定の削除
今回だと
<bean class="org.springframework.batch.core.configuration.support.JobRegistryBeanPostProcessor" p:jobRegistry-ref="jobRegistry"/>
タグを片方のxmlで削除。またはxmlの読み込みをやめる。
