 一、linux环境neo4j部署

默认账号密码：neo4j/neo4j

#解压缩

tar -zxvf neo4j-community-3.5.31-unix.tar.gz
#修改配置文件
vim ./conf/neo4j.conf
# 允许远程访问
dbms.connectors.default_listen_address=0.0.0.0
# 开启bolt服务，默认端口7687
dbms.connector.bolt.listen_address=:7687
# 开启http服务，默认端口7474
dbms.connector.http.listen_address=:7474
# 开启https服务，默认端口7473
dbms.connector.https.listen_address=:7473

cd neo4j-community-3.5.25/bin

#前台启动命令：
./neo4j console

#后台启动命令
./neo4j start
#状态
./neo4j status
#停止
./neo4j stop
#重启
./neo4j restart

#http访问
http://yourip:7474

#重置密码
connect:bolt://yourip:7687/

password:*

二、 java api操作neo4j

1.引入驱动包

<dependency>
            <groupId>org.neo4j.driver</groupId>
            <artifactId>neo4j-java-driver</artifactId>
            <version>4.2.0</version>
        </dependency>

2.java api

public class Neo4jDemo {
    public static void main(String[] args) {
        {
            Driver driver = GraphDatabase.driver("bolt://hw-node4:7687", AuthTokens.basic("neo4j", "****"));
            Session session = driver.session();
            session.run("CREATE (a:Person {name: {name}, title: {title}})",
                    parameters("name", "Dog", "title", "King"));

            Result result = session.run("MATCH (a:Person) WHERE a.name = {name} " +
                            "RETURN a.name AS name, a.title AS title",
                    parameters("name", "Dog"));
            while (result.hasNext()) {
                Record record = result.next();
                System.out.println(record.get("title").asString() + " " + record.get("name").asString());
            }
            session.close();
            driver.close();
        }
    }
}
