带密码

1.新建测试java文件neo4jJdbc.java:

[plain] view plain copy

print?

1. package n1;  
2. import java.sql.Connection;  
3. import java.sql.DriverManager;  
4. import java.sql.ResultSet;  
5. import java.sql.SQLException;  
6. import java.sql.Statement;  
7.   
8. import org.neo4j.jdbc.Driver;  
9. //Class.forName(“org.neo4j.jdbc.Driver”);  
10.   
11. //Connect  
12.   
13. public class neo4jJdbc {  
14.   
15.     public static void main(String[] args) throws SQLException {  
16.         // TODO Auto-generated method stub  
17.         Connection con = DriverManager.getConnection(“jdbc:neo4j://localhost:7474/”,”usrname”,”password”);  
18.   
19.         //Querying  
20.         try(Statement stmt = con.createStatement())  
21.         {  
22.          ResultSet rs = stmt.executeQuery(“MATCH (n) RETURN n”);  
23.          while(rs.next())  
24.          {  
25.              System.out.println(rs.getString(“n”));  
26.          }  
27.         }  
28.     }  
29.   
30. }  

package n1;import java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.SQLException;import java.sql.Statement;import org.neo4j.jdbc.Driver;//Class.forName("org.neo4j.jdbc.Driver");//Connectpublic class neo4jJdbc {    public static void main(String[] args) throws SQLException {        // TODO Auto-generated method stub        Connection con = DriverManager.getConnection("jdbc:neo4j://localhost:7474/","usrname","password");        //Querying        try(Statement stmt = con.createStatement())        {         ResultSet rs = stmt.executeQuery("MATCH (n) RETURN n");         while(rs.next())         {             System.out.println(rs.getString("n"));         }        }    }}

需要修改为你的ip和用户名以及密码

2.导入包：

Neo4j-2.0.1-SNAPSHOT Version：http://dist.neo4j.org/neo4j-jdbc/neo4j-jdbc-2.0.1-SNAPSHOT-jar-with-dependencies.jar

会报错：

 Embedded Neo4j support not enabled org/neo4j/graphdb/GraphDatabaseService

需要再导入：neo4j 的lib文件夹下的neo4j-kernel-2.3.0-M02.jar

3.往数据库写入文件：

http://localhost:7474/browser/

：play movies 

然后运行

查看的时候可以看到图

4.在java下查看，运行1中的java代码 ，运行结果：

[html] view plain copy
