沒有定義類型為[javax.persistence.EntityManagerFactory]的合格Bean ：：期望單個匹配的Bean，但找到2

Question

我有2個數據源bean，我正在使用spring boot，spring數據，我已經用@primary批注標記了一個數據源bean，但仍然出現錯誤： No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined:: expected single matching bean but found 2.

以下是我的2個數據庫配置類：

您能幫我嗎，如何避免這個錯誤。

我認為您的“ cacheConfiguration”需要通過注釋（@PersistenceUnit或@PersistenceContext）指定要使用的持久性單元名稱。
