无法移至Neo4j 2.2.0和Spring Data Neo4j 3.3.0. [英] Can't move to Neo4j 2.2.0 and Spring Data Neo4j 3.3.0.RELEASE

问题描述

我使用Spring 4.1.6.RELEASE和Spring Boot 1.2.3.RELEASE. 现在，我无法顺利地从Neo4j 2.1.7和SDN 3.2.2.RELEASE迁移到Neo4j 2.2.0和SDN 3.3.0.RELEASE

I use Spring 4.1.6.RELEASE and Spring Boot 1.2.3.RELEASE. Right now, I can't smoothly move from Neo4j 2.1.7 and SDN 3.2.2.RELEASE to Neo4j 2.2.0 and SDN 3.3.0.RELEASE

首先，没有Neo4jHelper类...所以应该改用什么?

First of all, Neo4jHelper class is absent... so what should be used instead ?

此外，我的测试因以下异常而崩溃:

Also, my tests crashes with a following exceptions:

org.springframework.dao.InvalidDataAccessApiUsageException: nested exception is org.neo4j.graphdb.NotInTransactionException
    at org.springframework.data.neo4j.support.Neo4jExceptionTranslator.translateExceptionIfPossible(Neo4jExceptionTranslator.java:51)
    at org.springframework.dao.support.ChainedPersistenceExceptionTranslator.translateExceptionIfPossible(ChainedPersistenceExceptionTranslator.java:59)
    at org.springframework.dao.support.DataAccessUtils.translateIfNecessary(DataAccessUtils.java:213)
    at org.springframework.dao.support.PersistenceExceptionTranslationInterceptor.invoke(PersistenceExceptionTranslationInterceptor.java:147)

    at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:207)

，但在以前的版本中，一切正常(我的DAO和服务都用@Transactional注释).

but on the previous versions everything work fine(My DAO and Services are annotated with @Transactional).

如何在我的Spring Boot应用程序中为Neo4j配置适当的TX管理器?

How to configure appropriate TX manager for Neo4j in my Spring Boot application ?

现在使用NullTransactionManager，我认为这是问题的原因:

Right now NullTransactionManager are used and I think this is a reason of the issue:

2015-04-03 11:40:36 [main] INFO  o.s.c.a.AnnotationConfigApplicationContext - Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@12db5286: startup date [Fri Apr 03 11:40:36 EEST 2015]; root of context hierarchy

我做错了什么?

推荐答案

这是正在进行的工作，我在分支中拥有它，但由于Neo4j 2.2更改了许多内部API，所以尚未完成.

This is work in progress, I have it in a branch but it's not done yet as Neo4j 2.2 changed many internal APIs.

下一周左右继续关注.
