我正在尝试使用 spring 创建一个沙箱来处理依赖注入。我的沙箱是几个域类,还有一个MainClass
,其中有一个main(String[] args)
方法。
在注释 my TestClass
with 时@Component
,它只包含
@Autowired
private Neo4jTemplate neo4jTemplate;
在里面。
在我的main
方法中,我调用ClassPathXmlApplicationContext
了我的applicationContext.xml
文件,该文件由以下部分组成:
<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 my 的行ClassPathXmlApplicationContext
,并带有大量堆栈跟踪,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?
