圖數據庫：neo4j：java測試連接util

簡單util： 

package com.neo4j;

import com.google.gson.Gson;
import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;
import org.neo4j.driver.*;

import java.io.BufferedReader;
import java.io.FileReader;
import java.util.Map;


/**
 * 類描述:  測試Neo4j的JavaAPI<br/>
 */
public class Neo4jTest {

    private static final String uri = "bolt://****/:7687";
//    private static final String uri = "bolt://****/:7687";
    private static final String user = "neo4j";
    private static final String password = "****";

    private static Driver driver;

    @BeforeClass
    public static void setup() {
        driver = GraphDatabase.driver(uri, AuthTokens.basic(user, password));
    }

    @AfterClass
    public static void teardown() {
        driver.close();
    }

    @Test
    public void test1() {
        try (Session session = driver.session()) {
            String query = "match(x:Hr_site{site_code:'10003'}) set x.curr_position='511947'";
            Result result = session.run(query);
            while (result.hasNext()) {
                Record record = result.next();
                Map<String, Object> stringObjectMap = record.asMap();
                Gson gson = new Gson();
                String json = gson.toJson(stringObjectMap);
                System.out.println("recordMap: " + stringObjectMap);
                System.out.println("json: " + json);
            }

        }

    }


    @Test
    public void addNode() {
        try (Session session = driver.session()) {

            String file = "/Users/yangbingyu/Desktop/untitled.sql";

            try{
                BufferedReader br = new BufferedReader(new FileReader(file));//構造一個BufferedReader類來讀取文件
                String s = null;
                while((s = br.readLine())!=null){//使用readLine方法，一次讀一行
                    session.run(s);
                }
                br.close();
            }catch(Exception e){
                e.printStackTrace();
            }

            System.out.println("Over!!!");
        }

    }


}

複雜util，可以批量執行語句
