我正在尝试在我的grails项目中使用spring-data-neo4j，但有很多版本存在冲突。
我正在使用以下依赖
编译org.springframework.data:spring-data-neo4j-rest:3.1.2.RELEASE
然后，如果我运行我的neo4j服务器2.1.2然后它给我错误
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'neo4jMappingContext' defined in class org.springframework.data.neo4j.config.Neo4jConfiguration: Invocation of init method failed; nested exception is java.lang.NullPointerException
... 4 more
Caused by: java.lang.NullPointerException

如果我运行1.8.3 neo4j服务器，那么它似乎连接到服务器但又出现错误
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'typeRepresentationStrategyFactory' defined in class org.springframework.data.neo4j.config.Neo4jConfiguration: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.data.neo4j.support.typerepresentation.TypeRepresentationStrategyFactory org.springframework.data.neo4j.config.Neo4jConfiguration.typeRepresentationStrategyFactory() throws java.lang.Exception] threw exception; nested exception is org.neo4j.rest.graphdb.RestResultException: expected START or CREATE
"MATCH (ref:ReferenceNode {name:{name}}) RETURN ref"

请让我知道我错过了什么，或者有人可以告诉我应该使用的确切版本。

我正在使用grails开发并使用在localhost：7474上运行的neo4j 2.1.2版本，我正在使用休息服务进行数据库连接
所以对于neo4j 2.1.2我得到了以下异常。
