试图让 Spring Data REST 和 Spring Data Neo4j 工作。

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

在 Jetty 上运行，启动正常，但在任何请求下，这是日志：

好吧，这是一个老问题，但我遇到了同样的错误，所以我添加了一个答案。

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

解决方案是从“src/main/webapp/WEB-INF/web.xml”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>
