使用 neo4j 2 有效设置弹簧数据-neo4f



我很难使用 spring-data-neo4j 和新的 neo4j 版本 2.0 来设置我的项目（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。相关的 maven 依赖项定义如下：

        <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>
        <artifactId>spring-aop</artifactId>
        <version>4.0.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.0.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-tx</artifactId>
        <version>4.0.0.RELEASE</version>
    </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，我收到以下异常：

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是一个简单的接口，扩展了GraphRepository。

该设置适用于最新的稳定版本，如果 spring-data-neo4j（在引擎盖下使用 neo4j 1.9）

有什么想法吗？

编辑：我的一个@NodeEntity上有一个属性，该属性具有以下索引定义：

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

如果删除此索引，则可以启动应用程序上下文。

我能够通过在我的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 地理空间"部分：我终于能够解决您添加这两个地理工具依赖项的相同问题。

我正在使用 SDN 3.0.1 和 neo4j 2.0.1

希望会有所帮助。

干杯
