Spring Neo4J REST error语言 - nodeStateTransmitter

Question

我一直在尝试让这个简单的例子运行(java 1.7) https://github.com/spring-guides/gs-accessing-neo4j-data-rest/tree/master/complete

当尝试通过application类中的main方法启动应用程序时，我一直得到以下错误:

我把整个日志上传到这个要点:http://bit.ly/1hU7Vpu

下面是错误总结。

WARN 6470 --- [           main] o.s.boot.SpringApplication               : Error handling failed (Error creating bean with name 'org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration': Initialization of bean failed; nested exception is java.lang.NoSuchMethodError: org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration.setBeanFactory(Lorg/springframework/beans/factory/BeanFactory;)V)

Answer 1

我认为您看到的是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(无论如何您可能不需要它)来防止此错误:

@Import(RepositoryRestMvcConfiguration.class)

可以显示mvn dependency:tree的输出吗?在你的类路径中可能有重复的Spring库。

编辑:

似乎是SDN的快照发布导致了这个问题。使用

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

不是

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

你可能发现了一个bug!
