带有SpringRestGraphDatabase的Neo4j - 找不到类的异常

我使用Spring数据图为Neo4J构建了一个新项目。我正在使用Maven。

嵌入式数据库的一切正常,但是当我尝试使用REST在远程服务器上设置数据库时,我得到了:


    java.lang.ClassNotFoundException: org.springframework.data.neo4j.rest.SpringRestGraphDatabase

我在大约一年前看过一个post,但没有解决方案 - 至少没有一个对我有用......在这篇文章中他们提到了我确实使用的aspectJ。

有人熟悉这个吗?有没有人有一个工作配置示例?

我真的尝试了不同配置的L-O-T,基于不同论坛和指南中的不同帖子。这是我的最后一个 - 我只是指定我还有其他POM,所有这些POM都由父POM分组(这是一个错误项目)。

这是bean的定义:

                               

        <!-- Neo4j configuration (creates Neo4jTemplate) -->
        <datagraph:config graphDatabaseService="neo4JRestGraphDatabase" />

           <!-- With this uncommented - it works great -->
        <!--datagraph:config storeDirectory="data/graph.db" /-->

这是该项目的POM:

3 个答案:

答案 0 :(得分:4)

如果您使用Spring Data,我认为您不想使用“org.neo4j”依赖项。我不是专家,但我目前的项目仅适用于:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-neo4j</artifactId>
    <version>${org.springframework.data-version}</version>
</dependency>
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-neo4j-rest</artifactId>
    <version>${org.springframework.data-version}</version>
</dependency>

答案 1 :(得分:1)

我认为您需要包含org.springframework.data.spring-data-neo4j-rest工件,而不仅仅是org.neo4j.neo4j-rest-graph-db

此外,你正在非常自由地混合版本

  • spring-data-neo4j 3.0快照
  • neo4j-rest-graphdb 2.0里程碑
  • neo4j 1.8里程碑(你确定你不是故意在这里使用2.0 M6吗?)
  • 一长串排除
  • 对spring-security-web 3.1.4和spring-orm的明确依赖

我不知道SDN 3的相关依赖性和兼容性,并且将它混合起来并不一定有任何问题,但如果你用pom得到ClassNotFoundExceptionNoClassDefFoundError像这样,您可能希望查看您的依赖关系树,例如在项目根目录中运行mvn dependency:tree -Dverbose,以查看是否存在冲突版本导致某些依赖项被静默排除。

答案 2 :(得分:0)

最后,问题是我的neo4JRestGraphDatabase的定义(遗憾的是我还没有粘贴在这里......)。

是:

<bean id="graphDatabaseService" class="org.springframework.data.neo4j.rest.RestGraphDatabase">
        <constructor-arg value="http://localhost:7474/db/data/" />
    </bean>

而不是:

<bean id="graphDatabaseService" class="org.springframework.data.neo4j.rest.SpringRestGraphDatabase">
        <constructor-arg value="http://localhost:7474/db/data/" />
    </bean>

现在我有'拒绝连接'问题,但这是another issue

关于依赖关系,上面提到的依赖关系确实足够了。

感谢任何想要帮助的人!
