Question

尝试使Spring Data REST和Spring Data Neo4j正常工作。

以下是来源：https://github.com/tony-landis/spring-data-neo4j-rest

在Jetty上运行，启动正常但在任何请求时这是日志：

Answer 1

这是一个老问题，但我有同样的错误，所以我添加了答案。

发生此错误是因为Spring Data Neo4j未提供OpenEntityManagerInViewFilter的实现。此过滤器仅与Spring Data JPA相关。

解决方案是从＆＃34; src / main / webapp / WEB-INF / web.xml＆＃34;中删除这些行：

<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>

没有定义类型为[javax.persistence.EntityManagerFactory]的限定bean
