Question

有人可以回答这个问题。是否可以在嵌入模式下的spring boot应用程序中使用空间存储库？

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

只需添加

即可

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

到您的类路径？

我一直收到错误

引起：java.lang.IllegalArgumentException：没有索引提供者＆＃39; spatial＆＃39;找到。也许预期的提供程序（或其中一个依赖项）不在类路径上，或者无法加载。 at 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）在org.springframework.data.neo4j.support.DelegatingGraphDatabase.createIndex（DelegatingGraphDatabase.java:163）在org.springframework.data.neo4j.support.index.IndexProviderImpl.createIndex（IndexProviderImpl.java:91） at org.springframework.data.neo4j.support.index.IndexProviderImpl.getIndex（IndexProviderImpl.java:68）在org.springframework.data.neo4j.support.index.IndexProviderImpl.getIndex（IndexProviderImpl.java:108）在org.springframework.data.neo4j.support.mapping.EntityIndexCreator $ 2.doWithPersistentProperty（EntityIndexCreator.java:61）在org.springframework.data.neo4j.support.mapping.EntityIndexCreator $ 2.doWithPersistentProperty（EntityIndexCreator.java:57）在org.springframework.data.mapping.model.BasicPersistentEntity.doWithProperties（BasicPersistentEntity.java:294）在org.springframework.data.neo4j.support.mapping.EntityIndexCreator.ensureEntityIndexes（EntityIndexCreator.java:57）在org.springframework.data.neo4j.support.mapping.Neo4jMappingContext.updateStoredEntityType（Neo4jMappingContext.java:78）在org.springframework.data.neo4j.support.mapping.Neo4jMappingContext.addPersistentEntity（Neo4jMappingContext.java:71）在org.springframework.data.neo4j.support.mapping.Neo4jMappingContext.addPersistentEntity（Neo4jMappingContext.java:49）在org.springframework.data.mapping.context.AbstractMappingContext.addPersistentEntity（AbstractMappingContext.java:257）在org.springframework.data.mapping.context.AbstractMappingContext.initialize（AbstractMappingContext.java:373）在org.springframework.data.neo4j.support.mapping.Neo4jMappingContext.initialize（Neo4jMappingContext.java:111）在org.springframework.data.mapping.context.AbstractMappingContext.afterPropertiesSet（AbstractMappingContext.java:363）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods（AbstractAutowireCapableBeanFactory.java:1625）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFactory.java:1562） ... 62更多

当然，你可以有弹簧数据neo4j + spring boot。

你可以找到我在这里写的代码：https://github.com/inserpio/neo4art 以及描述我是如何做到的简短帖子：https://inserpio.wordpress.com/2014/09/21/neo4art-moves-to-cloud-foundry-at-springone-2gx-2014/

希望它可以提供帮助！

干杯，洛伦佐

在maven pom中使用此存储库

            <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>

具有依赖性

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

嵌入式Neo4j中的SpatialRepository
