图计算neo4j系列2—— neo4j-java-driver

     这种方式是通过CQL(https://neo4j.com/developer/cypher)的方式进行数据操作。

一. pom配置

<dependency>

            <groupId>org.neo4j.driver</groupId>

            <artifactId>neo4j-java-driver</artifactId>

            <version>4.0.1</version>

</dependency>

参考：https://github.com/neo4j/neo4j-java-driver 或者

<dependency>

	<groupId>org.neo4j.driver</groupId>

	<artifactId>neo4j-java-driver-spring-boot-starter</artifactId>

	<version>4.1-SNAPSHOT</version>

</dependency>

二. 代码开发

import org.neo4j.driver.AuthTokens;

import org.neo4j.driver.Driver;

import org.neo4j.driver.GraphDatabase;

import org.neo4j.driver.Result;

import org.neo4j.driver.Record;

import org.neo4j.driver.Session;



import static org.neo4j.driver.Values.parameters;



public class DriverMain {

    public static void main(String[] args) {

        Driver driver = GraphDatabase.driver(

                "bolt://localhost:7687",

                AuthTokens.basic( "neo4j", "admin" ) );

        Session session = driver.session();



        session.run("CREATE (a:实体 {value: {value}})",

                parameters("value", "王菲"));



        final Result result = session.run("MATCH (a:实体) " +

                "RETURN a.value AS value");

        while ( result.hasNext() )

        {

            Record record = result.next();

            System.out.println( record.get( "value" ).asString()  );

        }

        session.close();

        driver.close();

    }

}
