嵌入式SpatialRepository在Neo4j中的应用

Question

有人能回答这个问题吗。是否有可能在嵌入式模式下在spring引导应用程序中拥有空间存储库？

  @Bean
       public GraphDatabaseService graphDatabaseService() {
          return new GraphDatabaseFactory().newEmbeddedDatabase("neo4j.db");
   }

只需添加

<dependency>
  <groupId>org.neo4j</groupId>
  <artifactId>neo4j-spatial</artifactId>
  <version>0.9</version>
</dependency>

到你的类路径上？

我一直在犯错误

原因: java.lang.IllegalArgumentException:没有找到索引提供程序“空间”。可能预期的提供程序(或者它的另一个依赖项)不在类路径上，或者它无法加载。在org.neo4j.kernel.impl.coreapi.IndexManagerImpl.getIndexProvider(IndexManagerImpl.java:91) at org.neo4j.kernel.impl.coreapi.IndexManagerImpl.findIndexConfig(IndexManagerImpl.java:142) at org.neo4j.kernel.impl.coreapi.IndexManagerImpl.getOrCreateIndexConfig(IndexManagerImpl.java:209) at org.neo4j.kernel.impl.coreapi.IndexManagerImpl.getOrCreateNodeIndex(IndexManagerImpl.java:314) at org.neo4j.kernel.impl.coreapi.IndexManagerImpl.forNodes(IndexManagerImpl.java:302) at org.springframework。data.neo4j.support.DelegatingGraphDatabase.createIndex(DelegatingGraphDatabase.java:163) at org.springframework.data.neo4j.support.index.IndexProviderImpl.createIndex(IndexProviderImpl.java:91) at org.springframework.data.neo4j.support.index.IndexProviderImpl.getIndex(IndexProviderImpl.java:68) at org.springframework.data.neo4j.support.index.IndexProviderImpl.getIndex(IndexProviderImpl.java:108) at org.springframework.data.neo4j.support.mapping.EntityIndexCreator$2.doWithPersistentProperty(EntityIndexCreator.java:61) at org.springframework.data.neo4j.support.mapping.EntityIndexCreator$2.doWithPersistentProperty(EntityIndexCreator.java:57) at org.springframework.data.mapping.model.BasicPersistentEntity.doWithProperties(BasicPersistentEntity.java:294) at org.springframework.data.neo4j.support.mapping.EntityIndexCreator.ensureEntityIndexes(EntityIndexCreator.java:57) at org.springframework.data.neo4j.support.mapping.Neo4jMappingContext.updateStoredEntityType(Neo4jMappingContext.java:78) at org.springframework.data.neo4j.support.mapping.Neo4jMappingContext.addPersistentEntity(Neo4jMappingContext.java:71)在org.springframework.data.neo4j.support.mapping.Neo4jMappingContext.addPersistentEntity(Neo4jMappingContext.java:49) at org.springframework.data.mapping.context.AbstractMappingContext.addPersistentEntity(AbstractMappingContext.java:257) at org.springframework.data.mapping.context.AbstractMappingContext.initialize(AbstractMappingContext.java:373) at org.springframework.data.neo4j.support.mapping.Neo4jMappingContext.initialize(Neo4jMappingContext.java:111) at org.springframework.data.mapping.context.AbstractMappingContext.afterPropertiesSet(AbstractMappingContext.java:363)在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1625) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1562) . 62

在maven pom中使用这个存储库

            <repository>
                        <id>neo4j-contrib-releases</id>
                        <url>https://raw.github.com/neo4j-contrib/m2/master/releases</url>
                        <releases>
                            <enabled>true</enabled>
                        </releases>
                        <snapshots>
                            <enabled>false</enabled>
                        </snapshots>
                    </repository>
                    <repository>
                        <id>neo4j-contrib-snapshots</id>
                        <url>https://raw.github.com/neo4j-contrib/m2/master/snapshots</url>
                        <releases>
                            <enabled>false</enabled>
                        </releases>
                        <snapshots>
                            <enabled>true</enabled>
                        </snapshots>
                    </repository>

带着依赖性

                <dependency>
                    <groupId>org.neo4j</groupId>
                    <artifactId>neo4j-spatial</artifactId>
                    <version>0.13-neo4j-2.1.2</version>
                </dependency>

当然，您可以使用spring数据neo4j + spring引导。

您可以找到我在这里编写的代码：https://github.com/inserpio/neo4art和一篇简短的文章，描述了我是如何做到的：https://inserpio.wordpress.com/2014/09/21/neo4art-moves-to-cloud-foundry-at-springone-2gx-2014/

希望能帮上忙！
