java - Spring Neo4J REST 错误 - nodeStateTransmitter

Question

我一直在尝试运行这个简单的示例(使用 java 1.7)https://github.com/spring-guides/gs-accessing-neo4j-data-rest/tree/master/complete

尝试通过 Application 类中的 main 方法启动应用程序时，我不断收到以下错误。

我将整个日志上传到此要点:http://bit.ly/1hU7Vpu

这是错误的摘要。

Answer 1

我认为您遇到了 Spring 版本冲突。请参阅错误日志中的以下行:

exception is java.lang.NoSuchMethodError: org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration.setBeanFactory(Lorg/springframework/beans/factory/BeanFactory;)V)

您应该能够通过删除以下行来防止此错误(您可能根本不需要它):

@Import(RepositoryRestMvcConfiguration.class)

你能显示mvn dependency:tree的输出吗？您的类路径上可能有重复的 Spring 库。

编辑:

看来是 SDN 的快照版本导致了该问题。使用

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-neo4j</artifactId>
    <version>3.0.1.RELEASE</version>
</dependency>

而不是

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-neo4j</artifactId>
    <version>3.1.0.BUILD-SNAPSHOT</version>
</dependency>

您可能发现了一个错误!
