我怎樣才能讓java和neo4j在eclipse中工作

我正在使用mint 17.2並且擁有neo4j 3.06 Comunity Edition，它在localhost：7474上正常運行。我怎樣才能讓java和neo4j在eclipse中工作

我希望在使用Eclipse Mars 2的Java 1.08中進行編程，但是我無法使其工作。

我使用的是Maven項目，並已在我的pom.xml以下

<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">

     <artifactId>neo4j-java-driver</artifactId> 
     <version>1.0.3</version> 
    </dependency> 
    </dependencies> 
</project>

我已經在我的app.java文件下列

package com.geekcap.informit.neo4j_sample_app; 


import org.neo4j.driver.v1.*; 

public class App 
{ 

    public static void main(String[] args) 
    { 
     Driver driver = GraphDatabase.driver("bolt://localhost:7474", AuthTokens.basic("neo4j", "neo4j")); 
     Session session = driver.session(); 

     session.run("CREATE (a:Person {name:'Arthur', title:'King'})"); 

     StatementResult result = 
      session.run("Match (a:Person) WHERE a.name = 'Arthur' RETURN a.name AS name, a.title AS title"); 
     while (result.hasNext()) { 
     Record record = result.next(); 
     System.out.println(record.get("title").asString() + " " + 
      record.get("name").asString()); 
     } 

     session.close(); 
     driver.close(); 
    }

我收到以下錯誤，當我嘗試運行它作爲一個Java應用程序。

7474端口是HTTP端口。由於您使用的是bolt://協議，因此您應該連接到7687端口。或實際刪除端口，因爲它的默認值：

Driver driver = GraphDatabase.driver("bolt://localhost", AuthTokens.basic("neo4j", "neo4j"));

還要確保博爾特協議是對Neo4j的情況下居然主動，由conf/neo4j.conf取消註釋（去掉前面的#）：

dbms.connector.bolt.address=0.0.0.0:7687

，或者至少，以限制到本地連接：

dbms.connector.bolt.address=127.0.0.1:7687

謝謝您的回覆弗蘭克。我嘗試了以上，它仍然無法正常工作。我使用端口7474，因爲我可以通過該端口訪問瀏覽器。 – Laurence

我敢打賭，協議是不活躍的，錯誤消息和堆棧跟蹤略有不同。我已經更新了答案。 –

嘗試從dbms.connector.bolt.address = 0.0.0.0：7687中刪除＃但它仍然失敗，但故障也已更改：無法處理請求：常規SSLEngine問題 – Laurence

SSL錯誤提示，客戶端需要加密的信道，但服務器未加密（因此異常堆棧跟蹤中的明文連接消息）。

回顧過去的Neo4j的手冊，你可能想看看下面的部分，瞭解如何配置客戶端和/或服務器進行任何加密或「純文本」：

您可以禁用SSL（顯然在生產中不推薦使用，但有用的診斷，如果這是你的問題）上的螺栓通道設置在neo4j.conf如下：

dbms.connector.bolt.tls_level=DISABLED

，然後重新啓動Neo4j的實例

感謝您的回覆。我嘗試設置dbms.connector.bolt.tls_level = DISABLED它是可選的，但它仍然失敗，我還試圖把第三個參數放在GraphDatabase.driver中，使它GraphDatabase.driver（「螺栓：//本地主機，AuthTokens.basic（「neo4j」，「neo4j」），Config.build（）。withEncryptionLevel（Config.EncryptionLevel.NONE）.toConfig（））; – Laurence
