使用 neo4j 2 有效设置 spring-data-neo4f答案

【问题标题】：Valid setup of spring-data-neo4f with neo4j 2使用 neo4j 2 有效设置 spring-data-neo4f
【发布时间】：2014-02-08 14:10:29
【问题描述】：

我很难使用 spring-data-neo4j 和新的 neo4j 2.0 版设置我的项目（因为我想在 neo4j 中使用新的标签）

经过一番挖掘，我在 maven 存储库中找到了 spring-data-neo4j 3.0.0.RC1。另外，我想使用neo4j-spatial。相关maven依赖定义如下：

        <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>4.0.0.RELEASE</version>
        <exclusions>
            <exclusion>
                <groupId>commons-logging</groupId>
                <artifactId>commons-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>

    </dependency>

    <dependency>

        <artifactId>spring-context</artifactId>

    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-tx</artifactId>

    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.0.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-neo4j</artifactId>
        <version>3.0.0.RC1</version>
        <exclusions>
            <exclusion>
                <groupId>org.hibernate.javax.persistence</groupId>
                <artifactId>hibernate-jpa-2.0-api</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.neo4j</groupId>
        <artifactId>neo4j-spatial</artifactId>
        <version>0.12-neo4j-2.0.0-M06</version>
    </dependency>

应用程序上下文遵循项目网站上的示例：

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

<neo4j:config storeDirectory="target/my.db"/>
<neo4j:repositories base-package="org.some.packages.repository"/>


<tx:annotation-driven mode="proxy"/>

我不使用 AspectJ。

当我启动项目时，我得到以下异常：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'someRepository': Invocation of init method failed; nested exception is org.neo4j.graphdb.TransactionFailureException: Unable to commit transaction

失败的 ´´´someRepository´´´ bean 是一个扩展 GraphRepository 的简单接口。

如果 spring-data-neo4j（在后台使用 neo4j 1.9），则该设置适用于最新的稳定版本

有什么想法吗？

编辑： 我的@NodeEntity 之一具有以下索引定义的属性：

    @Indexed(indexType = IndexType.POINT, indexName = "someIndexName", unique = false)

如果我删除这个索引，应用程序上下文就可以启动了。

我可以通过在我的 pom.xml 文件中添加一些其他依赖项来解决这个问题：

特别是请查看“Neo4j Geo-Spatial”部分：添加这两个地理工具依赖项后，我终于能够解决您的相同问题。

我正在使用 SDN 3.0.1 和 neo4j 2.0.1

希望会有所帮助。

干杯，

感谢您的回答。我现在没有太多时间处理这个项目，但是快速包含您建议的编辑看起来不错。只是我现在得到一个“未知的持久实体”异常。我将不得不检查这里发生了什么变化，然后再回复你的答案。
终于有时间研究一下。让它与你提到的版本一起工作。我不需要所有依赖项，但这可能取决于实际使用情况。我需要的是更多配置（从版本 3 开始，您需要定义基本包 ..）
