原因

因為配置了變數沒有建立該類或是沒在該類新增@Component

導致產生錯誤的配置

<!-- 訊息監聽容器  匯入索引庫-->
	<bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
		<property name="connectionFactory" ref="connectionFactory" />
		<property name="destination" ref="queueSolrDeleteDestination" />
		<property name="messageListener" ref="itemDeleteListener" />
	</bean>
 

解決

需要在指定標記itemDeleteListener類新增

@Component
