Question

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，但没有取得多大成功。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：

<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只指定商店目录（注释行），一切运行正常。我怀疑它是SDN和neo4j-server问题之间的版本。这是我的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>

它的父作为依赖Spring（核心，上下文，测试）3.2.0发布。

显示的具体错误是：

Caused by: java.lang.NoSuchFieldError: query_cache_size

就我而言，应该没有问题，因为default value是100. SDN文档没有谈论它too much。有什么建议吗？

提前谢谢大家。

看起来像版本兼容性问题。对我来说，下面的组合工作正常

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
