Question

由于以下原因，我无法配置TypeRepresentationStrategy：

无法将'org.neo4j.kernel.EmbeddedGraphDatabase'类型的值转换为所需类型'org.springframework.data.neo4j.core.GraphDatabase';

我使用Spring-Data-Neo4j 3.1.4和Neo4j 2.1.2。

这是因为我在spring-context配置中定义的graphDatabaseService实例是EmbeddedGraphDatabase的类型，请参阅我的配置：

<util:map id="config">
    <entry key="remote_shell_enabled" value="true"/>
    <entry key="cache-type" value="weak"/>
</util:map>

<bean id="graphDbFactory" class="org.neo4j.graphdb.factory.GraphDatabaseFactory"/>

<bean id="graphDbBuilder" factory-bean="graphDbFactory" factory-method="newEmbeddedDatabaseBuilder">
    <constructor-arg value="target/neo4j-db-plain"/>
</bean>

<bean id="graphDbBuilderFinal" factory-bean="graphDbBuilder" factory-method="setConfig">
    <constructor-arg ref="config"/>
</bean>

<bean id="graphDatabaseService" factory-bean="graphDbBuilderFinal" factory-method="newGraphDatabase"
      destroy-method="shutdown"/>

<bean id="serverWrapper" class="org.neo4j.server.WrappingNeoServerBootstrapper" init-method="start"
      destroy-method="stop">
    <constructor-arg ref="graphDatabaseService"/>
</bean>

<neo4j:config base-package="com.hobbydeed.graph.model" graphDatabaseService="graphDatabaseService" />

<bean id="typeRepresentationStrategyFactory" class="org.springframework.data.neo4j.support.typerepresentation.TypeRepresentationStrategyFactory">
    <constructor-arg index="0" ref="graphDatabaseService"/>
    <constructor-arg type="org.springframework.data.neo4j.support.typerepresentation.TypeRepresentationStrategyFactory.Strategy">
        <value>Indexed</value>
    </constructor-arg>
</bean>

问题是如何在TypeRepresentation org.neo4j.kernel.EmbeddedGraphDatabase implements时将org.neo4j.graphdb.GraphDatabaseService配置为“已建立索引”，但TypeRepresentationFactory想要org.springframework.data.neo4j.core.GraphDatabase？< / p>

Answer 1

您可以使用所选策略覆盖nodeTypeRepresentationStrategy bean。

对于您使用的策略工厂，您只需使用＆＃34; graphDatabase＆＃34; bean参考。

或者您使用DelegatingGraphDatabase(graphDatabaseService)作为graphDatabase的bean，这是默认值。

为EmbeddedGraphDatabase配置TypeRepresentationStrategy
