我正在尝试将我们项目的“spring-data-neo4j”依赖项从 2-1-0-M1 版本（使用 neo4j 1.6）升级到 2.2.0.RELEASE（使用 neo4j 1.8.1）版本。但是，当我将 spring-data-neo4j 依赖项的版本更改为 2.1.0.RELEASE 时，在 Tomcat 上启动应用程序时出现以下异常：

[ERROR] [host-startStop-1] [org.springframework.web.context.ContextLoader:307] - Context initialization failed

我还尝试仅“升级”“spring-data-neo4j”库（并在 v1.6 上使用 neo4j）并且也遇到了异常。因此，该异常似乎仅与 spring-data-neo4j 库有关，与 neo4j 本身无关。

以前有没有人见过这种行为，或者有任何线索为什么 Spring-data-neo4j 认为 RuntimeException 应该是 NodeEntity 或 RelationshipEntity？

不幸的是，代码分布在多个项目中，因此很难在此处粘贴导致问题的最低配置。仍在努力。已经通过删除所有注释和内容来“清理”所有 neo4j 实体（和关系）类和 DAO，以确保它与它们中的任何一个都不相关。尽管如此，在启动应用程序时还是会出现异常。

编辑：下面是使用的弹簧配置：

            </bean>
        </property>
    </bean>

</beans>

编辑 21-05：找到原因，在某些应用程序上下文中定义了以下 bean：

<bean id="runtimeException" class="java.lang.Class" factory-method="forName">
    <constructor-arg value="java.lang.RuntimeException"/>
</bean>

删除这个 bean（它是为 spring-batch 的 FaultTolerantStepFactoryBean 的 skippableExceptionClasses 属性定义的）解决了这个问题。不知何故，neo4j 组件扫描发现了这个 bean？
