我有一个spring boot应用程序，它可以休息调用neo4j。我正在使用以下maven依赖 -
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-neo4j-rest</artifactId>
<version>3.3.0.RELEASE</version>
</dependency>
<dependency>

</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons</artifactId>
<version>1.10.2.RELEASE</version>
</dependency>
使用Neo4j 2.2.3，Rest App工作正常。在我将Neo4j升级到2.3.3之后，Rest App并未工作。我得到了依赖性问题。 Maven无法下载Neo4j 2.3.3 jar，即使我尝试使用spring-data-neo4j-rest（3.4.4.RELEASE）和spring-data-neo4j（4.0.0.RELEASE）的最新版本的工件。 请告诉我用于Neo4j 2.3.3的spring-data-neo4j-rest和spring-data-neo4j的工件版本。 这是我得到的错误 -
