Spring Data Neo4j:使用带有嵌入式的服务器 [英] Spring Data Neo4j: Using the server with an embedded

问题描述

我正在尝试配置我的应用程序上下文，以便能够在我的应用程序中使用带有嵌入式图形的 Neo4j 服务器，但没有取得太大成功.我同时使用 Spring Data(Mongo 和 Neo4j 存储库方法).这是我的应用程序上下文，它没有运行:

I'm trying to configure my application context in order to be able to use the Neo4j server with an embedded graph in my app without much success. I'm using Spring Data at the same time (both Mongo and Neo4j repositories approach). This is my application-context, which isn't running:

<context:component-scan base-package="org.domain.team.project.*"/>

<mongo:repositories base-package="org.domain.team.project.data.repositories.mongodb"/>

    <!-- Neo4j -->
    <!--  <neo4j:config storeDirectory="/data/production/graph.db"/> -->
    <neo4j:repositories base-package="org.domain.team.project.data.repositories.neo4j"/>

    <neo4j:config graphDatabaseService="graphDatabaseService" />
    <bean id="graphDatabaseService" class="org.neo4j.kernel.EmbeddedGraphDatabase"
    destroy-method="shutdown">
        <constructor-arg index="0" value="/data/production/graph.db" />
        <constructor-arg index="1">
            <map><entry key="enable_remote_shell" value="true"/></map>
        </constructor-arg>
    </bean>
    <bean id="serverWrapper" class="org.neo4j.server.WrappingNeoServerBootstrapper" 
        init-method="start" destroy-method="stop">
            <constructor-arg ref="graphDatabaseService"/>
    </bean>

如果我不使用这种方法并简单地指定商店目录(注释行)，则一切正常.我怀疑这是 SDN 和 neo4j-server 问题之间的一个版本.这是我的 POM:

If I don't use this approach and specify simply the store directory (commented line) everything runs fine. I suspect it's a version between SDN and neo4j-server issue. This is my POM:

  <properties>
    <spring.data.mongo.version>1.1.0.RELEASE</spring.data.mongo.version>
    <spring.data.neo4j.version>2.1.0.RELEASE</spring.data.neo4j.version>
  </properties>

  <dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-mongodb</artifactId>
        <version>${spring.data.mongo.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-neo4j</artifactId>
        <version>${spring.data.neo4j.version}</version>
    </dependency>
    <dependency>
        <groupId>org.neo4j.app</groupId>
        <artifactId>neo4j-server</artifactId>
        <version>1.8.2</version>
    </dependency>
    <dependency>
        <groupId>org.neo4j.app</groupId>
        <artifactId>neo4j-server</artifactId>
        <classifier>static-web</classifier>
        <version>1.8.2</version>
    </dependency>
  </dependencies>

它的父级依赖 Spring(core,context,test) 3.2.0 Release.

Its parent has as a dependency Spring(core,context,test) 3.2.0 Release.

显示的具体错误是:

Caused by: java.lang.NoSuchFieldError: query_cache_size

就我而言，作为 默认值应该没问题 是 100.SDN 文档没有提到 太多.有什么建议吗?

which as far as I am concerned, should be no problem as the default value is 100. The SDN doc does not talk too much about it. Any suggestions?

先谢谢大家.

推荐答案

看起来是版本兼容性问题.对我来说，下面的组合工作正常

Looks like version compatibility issue. For me below combination is working fine

spring-data-neo4j : 2.1.0.RC4
spring-data-mongodb : 1.1.0.RELEASE 
neo4j-server : 1.8
static-web : 1.8

此外，我正在使用-

Spring framework version : 3.1.2.RELEASE
Neo4j version : 1.8
mongodb version : 2.2.2
mongo-java-driver : 2.9.1
slf4j : 1.7.2
