Apache Camel - JpaConsumer失敗的輪詢端點

我在嘗試輪詢JPA實體Person時收到以下錯誤。代碼中沒有錯誤。所有的東西都編譯成mvn乾淨的安裝，而Person實體確實存在於net.lr.tutorial.karaf.camel.jpa2jms.model包中。我已經安裝了所有我認爲必要的功能，並且我知道它正確連接到數據庫，因爲它正在爲主鍵創建序列數據庫。Apache Camel - JpaConsumer失敗的輪詢端點

任何想法？

您是否重置了'Person'實體的名稱屬性，即'@Entity（name =「Person」）'？ –

是的，我做到了。我的JPA類看起來像 - @Entity（name =「person」） [code] @XmlType @XmlRootElement public class Person {[/ code] –

你可以嘗試以下方法：

取出@Entity註釋如果可能的name屬性。
檢查是否在persistence.xml中添加了正確的Person類。它應該是net.lr.tutorial.karaf.camel.jpa2jms.model.Person而不是jms.model.Person

我希望它有幫助。
