java连接neo4j

<div id="cnblogs\_post\_body" class="blogpost-body">呼、博客要落灰了 记录一下Java连接neo4j的问题。 首先是neo4j的下载和配置，基本参考https://blog.csdn.net/appleyk/article/details/79091898 1、下载jdk 2、下载neo4j的community版本或者desktop版本下载地址：https://neo4j.com/download-center/ 3、配置环境变量 NEO4J\_HOME=解压地址、path=%NEO4J\_HOME%\\bin; 4、验证是否安装成功:在cmd中运行neo4j.bat console 5、注册neo4j服务：neo4j install-service 6、注册后就可以使用neo4j start 来启动服务。 然后是在eclipse中新建maven项目 1、利用maven导入neo4j和java连接的包neo4j-java-driver <div class="cnblogs\_code"><div class="cnblogs\_code\_toolbar"><a href="javascript:void(0);" onclick="copyCnblogsCode(this)" title="复制代码"><img src="https://my.oschina.net//common.cnblogs.com/images/copycode.gif" alt="复制代码"></a></div> <pre><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.recom</groupId> <artifactId>recommender</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencies>  <dependency> <groupId>org.neo4j.driver</groupId> <artifactId>neo4j-java-driver</artifactId> <version>1.7.2</version> </dependency>
