未定義[javax.persistence.EntityManagerFactory]類型的限定bean

Question

嘗試獲取Spring Data REST和Spring Data Neo4j的工作方式。

這裏是源：https://github.com/tony-landis/spring-data-neo4j-rest

運行在碼頭，開始了正常，但在任何請求，這是日誌：

Answer 1

嗯，這是一個老問題，但我有同樣的錯誤，所以我添加一個答案。

發生此錯誤是因爲Spring Data Neo4j沒有提供OpenEntityManagerInViewFilter的實現。此過濾器僅與Spring Data JPA相關。

解決方案是從 「的src /主/ web應用/ WEB-INF/web.xml文件」 刪除這些行：

<filter> 
    <filter-name>OpenEntityManagerInViewFilter</filter-name> 
    <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class> 
</filter> 
<filter-mapping> 
    <filter-name>OpenEntityManagerInViewFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
</filter-mapping>
