我按照以下链接中的说明操作,但是,当我运行程序并转到http://localhost:7474/
时,网络管理员的网页不可用。
How to connect to a locally installed neo4j server using Java
Neo4j Hello World Tutorial and webadmin
Wrapping server bootstrapper is deprecated, what is the alternative?
http://devender.wordpress.com/2011/10/17/neo4j-running-embedded-server-with-webconsole/
use WrappingNeoServerBootstrapper with spring-data-neo4j
我确实设法一个接一个地运行Java程序和neo4j服务器(指向相同的DB_PATH),但我需要的是同时运行程序和Web管理员,以便我可以看到程序在做什么实时。
任何想法我做错了或在2.1.5版本中根本不可能?
我的pom.xml具有以下依赖项:
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j</artifactId>
<version>2.1.5</version>
</dependency>
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<version>2.1.5</version>
</dependency>
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<version>2.1.5</version>
<type>jar</type>
<classifier>static-web</classifier>
</dependency>
Java程序包含:
private GraphDatabaseService graphDb = null;
private WrappingNeoServerBootstrapper server = null;
void start() {
graphDb = new GraphDatabaseFactory()
.newEmbeddedDatabase(DB_PATH);
server = new WrappingNeoServerBootstrapper((GraphDatabaseAPI) graphDb);
server.start();
}
我注意到在我的项目文件夹中创建了一个文件messages.log
。它表示服务器启动时存在NoSuchMethodError
异常。您有任何想法如何解决这个问题吗?

这是我一直在使用的(在2.1.3上,希望在2.1.5上也一样) -
WrappingNeoServerBootstrapper neoServerBootstrapper;
GraphDatabaseService db = new GraphDatabaseFactory().newEmbeddedDatabaseBuilder("/path/to/db").newGraphDatabase();
registerShutdownHook(db);
try {
GraphDatabaseAPI api = (GraphDatabaseAPI) db;
ServerConfigurator config = new ServerConfigurator(api);
config.configuration().addProperty(Configurator.WEBSERVER_ADDRESS_PROPERTY_KEY, "127.0.0.1");
config.configuration().addProperty(Configurator.WEBSERVER_PORT_PROPERTY_KEY, "7575");
neoServerBootstrapper = new WrappingNeoServerBootstrapper(api, config);
neoServerBootstrapper.start();
}
catch(Exception e) {
//log it
}
