spring - 问题将 spring-data-neo4j 独立 spring 项目连接在一起

Question

我正在尝试使用 spring 创建一个沙箱来处理依赖注入(inject)。我的沙箱是几个域类，还有一个 MainClass ，其中有 main(String[] args)里面的方法。

在注释我的 TestClass与 @Component它只包含

@Autowired
private Neo4jTemplate neo4jTemplate;

在里面。

在我的 main方法，我调用 ClassPathXmlApplicationContext在我的 applicationContext.xml文件，它由以下部分组成:

<context:annotation-config/>
<context:spring-configured/>
<context:component-scan base-package="org.neuralsandbox"/>

<neo4j:config storeDirectory="data/sandbox.db"/>

但是我的程序无法在此处执行我声明我的 ClassPathXmlApplicationContext ，通过大量的堆栈跟踪，我将打印第一个和最后一个 throwable。

第一的:

我正在使用 neo4j 1.7 和 spring-data-neo4j 2.0.0.RELEASE，以及 spring 3.1.0.RELEASE。

我没有找到一个很好的理由，使用 spring-data-neo4j 提供的教程，为什么它会抛出这个异常。任何人都可以帮忙吗？

Answer 1

我发现这是我使用的 spring-data-neo4j 和 neo4j 混合的问题。

在 spring-data-neo4j 2.0.1.RELEASE 中，Neo4jConfiguration正在尝试使用 SpringTransactionManager和 UserTransactionImpl接受 AbstractGraphDatabase类，在 neo4j 1.7 SpringTransactionManager不接受它，在 neo4j 1.8.M01 中，UserTransactionImpl不接受。

所以现在的解决方案是使用 neo4j 1.6.2 和 spring-data-neo4j 2.0.1.RELEASE。
