spring-data-neo4j-4

问题 I would like to use the new bolt protocol to connect my spring application to neo4j 3.0 database. Is bolt protocol already implemented in spring data? 回答1: Yes, these versions support Bolt: Neo4j OGM 2.0.2, which can be used with SDN 4.1.1.RELEASE (you will need to explicitly include this Neo4j OGM version). Or the current SDN snapshot 4.2.0.BUILD-SNAPSHOT which depends on the latest Neo4j OGM snapshot. The Bolt Driver dependency is also required: <dependency> <groupId>org.neo4j</groupId>

问题 We've hit an issue when upgrading from spring-boot 1.3.2 to the recently released 1.3.3. Our application has been making use of the following dependencies, each the latest, without issue: <neo4j.version>2.3.2</neo4j.version> <sdn.version>4.0.0.RELEASE</sdn.version> <sdn.rest.version>3.4.0.RELEASE</sdn.rest.version> <neo4j.ogm.version>1.1.5</neo4j.ogm.version> Today I upgraded our spring-boot and Spring Data Neo4j -based application, which starts and works well with spring-boot 1.3.2.RELEASE,

问题 I have some logic which needs direct node access to neo4j but the rest of the app using Spring Data Neo4j (SDN) for simplicity. I thought to use a procedure with @Procedure, but I'm not sure how to use that procedure when using the neo4j embedded driver and SDN4. My configuration is very barebones as below: @Configuration @EnableNeo4jRepositories(basePackages = "recommender.repository") @ComponentScan(basePackages = "recommender") @EnableTransactionManagement public class MyNeo4jConfiguration

问题 I am trying to use Jackson 2.x annotations on a Spring Data Neo4j 4.0.0RC1 entity but am seeing failures in my application context starting. I have two @NodeEntities that implement an interface and I've annotated the interface as such: @JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "type") @JsonSubTypes({ @Type(value = SimpleNode.class, name="simple"), @Type(value = OtherNode.class, name="other") }) public interface Node { } I believe this is correct

问题 I'm using the following java configuration for my Neo4j (using SDN 4.0.0.RELEASE) based application, with unit tests: ... @Bean public Neo4jServer neo4jServer() { return new InProcessServer(); } @Bean public SessionFactory getSessionFactory() { Neo4jRequest<String> neo4jRequest = new DefaultRequest(httpClient); String json = "{" + "\"name\" : \"node_auto_index\", " + "\"config\" : {" + "\"type\" : \"fulltext\", " + "\"provider\" : \"lucene\"" + "}" + "}"; neo4jRequest.execute(neo4jServer()

问题 In my Neo4j/SDN project I have to implement a following task - I have a parent Node(let's say ParentNode ) that must define a set of product characteristics, for example: weight: Double size: Integer license: String active: Boolean Also, new product characteristics( with any new name and type ) can be added during the application runtime. ParentNode can have a set of child nodes(let's say ProductNode ) and each of these nodes can provide an own value for a certain characteristic defined by a

问题 I'm getting the following error with Spring Data Neo4j 4. I think it could be a dependency conflict but I'm not sure what. java.lang.IllegalStateException: Failed to load ApplicationContext at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:124) at org.springframework.test.context.support.DefaultTestContext.getApplicationContext(DefaultTestContext.java:83) at org.springframework.test.context.web

问题 I am running into an issue wherein some of my Neo4J queries like the one below ends up in an OGM AmbiguousBaseClassException while others don't. For example findByTitle for the movie "The Score" throws an exception but "The Matrix" does not. My graph is populated by the Movie Database found at https://neo4j.com/developer/example-data/ I am unable to find an explanation to the above observation and I hope someone can help. curl http://localhost:8080/movies/search/findByTitle?title=The%20Score

问题 I have setup using spring-data-neo4j v 4.2.1, neo4j-ogm v 2.1.2. I need embedded neo4j server with specific configuration for testing. cypher.forbid_shortestpath_common_nodes=false . I tried this without success in spring @Configuration bean: @Bean public org.neo4j.ogm.config.Configuration getConfiguration() { org.neo4j.ogm.config.Configuration config = new org.neo4j.ogm.config.Configuration(); config.driverConfiguration().setDriverClassName("org.neo4j.ogm.drivers.embedded.driver
