spring-data-neo4j

问题 I just learnt that when I create a relationship between 2 nodes in neo4j, both of them are locked (http://docs.neo4j.org/chunked/stable/transactions-locking.html). However, in our project, we have elements that we can instanciate and we finnaly have two nodes in the graph linked by a "INSTANCE_OF" relationship. For exemple if I instanciate element B, I have a new element B1. They are stored in the graph like B<-INSTANCE_OF-B1. My problem is that many users can instanciate element B on same

问题 Getting following error while running maven test on project. I am building a test application using Spring Data Neo4j. java.lang.IllegalStateException: Failed to load ApplicationContext at org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:157) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:109) at org.springframework.test.context.support

问题 I'm currently evaluating OGM / Spring Data Neo4j for a use case and came upon the following problem: When executing a custom Cypher query either via Spring Data @Query annotation or directly via the Neo4j Session , the result contains only the nodes directly queried for and not the related nodes (relationships are null in the resulting node objects). I.e. the depth for these queries seems to be 0 and not 1, as I would have expected from the docs. How can I execute a custom Cypher query via

问题 In my Neo4j database I have a following entities: @NodeEntity public class Product { private final static String CONTAINS = "CONTAINS"; private final static String DEFINED_BY = "DEFINED_BY"; private final static String VOTED_FOR = "VOTED_FOR"; private final static String PARENT = "PARENT"; private final static String CREATED_BY = "CREATED_BY"; @GraphId private Long id; @RelatedTo(type = PARENT, direction = Direction.INCOMING) private Product parent; @RelatedTo(type = CONTAINS, direction =

问题 Today I tried Spring Data Neo4j, I finally got it working somehow ... I'm using: Spring 4.0.2 Spring Data Neo4j 3.0.0 QueryDSL 3.3.1 Neo4j 2.0.1 Here's my config: @Configuration @EnableNeo4jRepositories(includeFilters=@Filter(value=GraphRepository.class, type=FilterType.ASSIGNABLE_TYPE)) public class Neo4jConfig extends Neo4jConfiguration { public Neo4jConfig() { setBasePackage("my.base.package"); } @Bean public GraphDatabaseService graphDatabaseService() { return new GraphDatabaseFactory()

问题 I have made a simple Repository containing all the persons in my system, everything seems to work fine. I can add, remove and even retrieve single persons based on a given key and value but for some reason i can't retrieve all persons stored in the Repository directly. I tried do it by using the findAll() method, which should return an iterable. I then try to iterate with the iterable and store each person in an arraylist which i want the function to return. public List<Person> getAllPersons(

问题 I'm trying to make neo4j-spatial version 0.14-neo4j-2.2.0, works with spring-data-neo4j-rest version 3.3.0.RELEASE with neo4j CE 2.2.1 in server mode. It looks like they are not compatible. Trying to create new instance of class EditableLayer throws NoSuchMethod exception. For instance: EditableLayer layer = (EditableLayer) spatialDb.getOrCreateLayer( "layer",SimplePointEncoder.class, EditableLayerImpl.class); I get the exception: SEVERE: Servlet.service() for servlet [com.stampy.foundation

问题 I try to write a webapp using Spring Data Neo4j.

问题 I'm trying to move away from manually-managed transactions to annotation based transactions in my Neo4j application. I've prepared annotation-based Spring configuration file: @Configuration @EnableNeo4jRepositories("xxx.yyy.neo4jplanetspersistence.repositories") @ComponentScan(basePackages = "xxx.yyy") @EnableTransactionManagement public class SpringDataConfiguration extends Neo4jConfiguration implements TransactionManagementConfigurer{ public SpringDataConfiguration() { super();
