基於前兩篇的實現，這是第三種，這種最不好用，但是也可用。

1.程式碼實現

package neo4j.util;

import org.neo4j.driver.v1.*;

/**
 * description: 通過嵌入式方式獲取Driver
 *
/
public class NeojUtil {
    private volatile static Driver driver = null;


    /**
     * 獲取連線driver
     * @return
     */
    private static Driver getGraphBaseDriver() {
        try
 
 {
            if (driver != null) {

            } else {
                Thread.sleep(300);
                synchronized (NeojUtil.class) {
                    if (driver == null) {//二次檢查
                        driver = GraphDatabase.driver("bolt://localhost:7687",
                                AuthTokens.basic("username"
 
, "password"));
                    }
                }
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return driver;
    }

    public static Transaction getTransaction(){
        Session session = getGraphBaseDriver().session();
        Transaction tx = session.beginTransaction();
        tx.run("statement"
 
);
        return  tx;
    }

}
