How to configure Neo4j embedded to run apoc procedures?

I have setup Neo4j using the latest spring 1.5 release, spring-data-neo4j 4.2, with ogm drivers. The configuration is using embedded driver without URI (so impermanent database store) Here is the spring @Configuration bean content: @Bean public org.neo4j.ogm.config.Configuration neo4jConfiguration() { org.neo4j.ogm.config.Configuration configuration = new org.neo4j.ogm.config.Configuration(); configuration.driverConfiguration().setDriverClassName("org.neo4j.ogm.drivers.embedded.driver.EmbeddedDriver"); // don't set the URI for embedded so we get an impermanent database return configuration; }

带密码的 Neo4j 嵌入式模式(Neo4j Embedded Mode with Password)

问题 您可以在 Java 应用程序中以嵌入模式连接到 Neo4j 以连接到需要用户名和密码的现有运行 Neo4J 服务器吗? 你是怎样做的? 显然没有身份验证它是: graphDb = new GraphDatabaseFactory().newEmbeddedDatabase( DB_PATH ); registerShutdownHook( graphDb ); 回答1 Http 身份验证是 Neo4j 服务器组件的一部分。 您使用的代码片段运行嵌入式数据库实例。 如果 a) 您想要一些代码连接到正在运行的 Neo4j 远程实例,或者 b) 您想要运行自己的嵌入式实例并在其上运行 Web 界面,请澄清您的问题? 在 a) 的情况下,您可以使用事务性 Cypher 端点,使用 Neo4j JDBC 驱动程序或(从 Neo4j 开始)java bolt 驱动程序。 在 b) 的情况下,您需要查看 Neo4j 的源代码以了解org.neo4j.server.Bootstrapper及其派生类正在做什么。 有了这些,您可以在嵌入式实例之上运行您的服务器。

Neo4j Embedded Mode with Password

Can you connect to Neo4j in embedded mode in a Java application to connect to an existing running Neo4J server that requires a username and password? How do you do that? Apparently without authentication it is: graphDb = new GraphDatabaseFactory().newEmbeddedDatabase( DB_PATH ); registerShutdownHook( graphDb );

如何解决 java.lang.NoSuchMethodError: org.neo4j.helpers.collection.Iterables.toList(Ljava/lang/Iterable;)Ljava/util/List?(How can I resolve java.lang.NoSuchMethodError: org.neo4j.helpers.collection.Iterables.toList(Ljava/lang/Iterable;)Ljava/util/List?)

问题 我正在尝试使用 Java 中的嵌入式 neo4j 在 neo4j 中插入节点,但我收到此错误,我使用的是 neo4j 3.1.1 和 netbeans 7 Exception in thread "main" java.lang.NoSuchMethodError: org.neo4j.helpers.collection.Iterables.toList(Ljava/lang/Iterable;)Ljava/util/List; at org.neo4j.graphdb.factory.GraphDatabaseFactory.<init>(GraphDatabaseFactory.java:49) at twitter4j.EmbeddeNeo4j.createDb(EmbeddeNeo4j.java:41) 我不知道变量DB_PATH = "D:\\Neo4j CE 3.1.1\\graph database"是否应该包含变量DB_PATH ? 代码是: void createDb() { clearDb(); // start DB graphDb = new GraphDatabaseFactory().newEmbeddedDatabase(DB_PATH); registerShutdownHook(graphDb); // start Transaction

启用非托管扩展配置后 Neo4J 服务器启动错误(Neo4J server startup error after enabling the unmanaged extension configuration)

问题 我在 Windows OS 10 上使用 Neo4J 社区版 2.3.0。一切正常,直到我将neo4j-server.properties文件中的配置更改为: org.neo4j.server.thirdparty_jaxrs_classes=org.neo4j.examples.server.unmanaged=/examples/unmanaged 服务器启动时的错误是: 启动 Neo4j 失败:org.neo4j.server.web.NeoServletContainer-5b85e832@73766070==org.neo4j.server.web.NeoServletContainer,-1,false 如果我禁用此更改,则服务器启动得很好。 我正在尝试运行 Neo4J 教程中给出的非托管扩展的 HelloWorld 示例,并按照所有说明进行操作。 用于构建 Jar 的 Java 编译器是 1.7,我正在研究 STS 工具。 尽早做出回应会有所帮助。 控制台日志如下 [o.n.s.d.LifecycleManagingDatabase] Successfully started database 2016-01-04 16:49:08.036+0530 INFO [o.n.s.CommunityNeoServer] Starting HTTP on port

Neo4J server startup error after enabling the unmanaged extension configuration

I am using Neo4J community edition 2.3.0 on windows OS 10. Everything works well until I changed the configuration at neo4j-server.properties files as: org.neo4j.server.thirdparty_jaxrs_classes=org.neo4j.examples.server.unmanaged=/examples/unmanaged The error at server startup is: Starting Neo4j failed: org.neo4j.server.web.NeoServletContainer-5b85e832@73766070==org.neo4j.server.web.NeoServletContainer,-1,false If I disable this change then server starts very well. I am trying to run the HelloWorld example for the unmanaged extension as given with the Neo4J tutorial and follow all the
