Scala spring-data-neo4j-创建名为';neo4jTemplate&x27;
我试图将neo4j与spring数据和scala一起使用,但我遇到了以下异常:Scala spring-data-neo4j-创建名为';neo4jTemplate&x27;,scala,neo4j,spring-data-neo4j,Scala,Neo4j,Spring Data Neo4j,我试图将neo4j与spring数据和scala一起使用,但我遇到了以下异常: Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'neo4jTemplate': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError:scala.collect
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'neo4jTemplate': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError:scala.collection.JavaConverters$.mapAsScalaMapConverter(Ljava/util/Map;)Lscala/collection/JavaConverters$AsScala;
现在,我不确定如何“注入”JavaConverter
有什么想法吗
更新:
我尝试将导入简单地放在测试类中:
导入scala.collection.JavaConverters_
但不起作用,以下是完整的代码:

更新:
我解决了
问题是scala版本,我使用的是2.10,但它必须是2.9.2scala for neo4j将在下一个里程碑版本中更新为2.10。谢谢!这是个好消息!
