spring 数据 neo4j 嵌入式:连接到 localhost:7474 失败:连接被拒绝

spring data neo4j Embedded : Connect to localhost:7474 failed: Connection refused

具有此配置:

@Configuration
@EnableNeo4jRepositories("com.mydb.repository")
@EnableTransactionManagement
public class Neo4jConfig extends Neo4jConfiguration {
    @Bean
    @Override
    public Neo4jServer neo4jServer() {
        return new RemoteServer( "http://localhost:7474" );
    }       
    @Bean
    public GraphDatabaseService graphDatabaseService() {

        return new GraphDatabaseFactory().newEmbeddedDatabaseBuilder( new File("./mydb.db") )
                .setConfig( ServerSettings.auth_enabled, Boolean.FALSE.toString() )             
                .newGraphDatabase();

    }    
    @Bean
    @Override
    @Scope(proxyMode = ScopedProxyMode.TARGET_CLASS)
    public Session getSession() throws Exception {
        return super.getSession();
    }        
    @Bean
    @Override
    public SessionFactory getSessionFactory() {
        return new SessionFactory("com.mydb.model");
    }    
}

我有 2 个错误:

1_ 我无法将 Session 保持在范围内 "session"

2_ 我有异常:连接到 localhost:7474 失败:连接被拒绝:

服务器是嵌入式的,它应该无需在我的本地计算机上安装任何服务器即可启动?

Spring-boot 1.3.0 (Last) and 
<dependency>
        <groupId>org.neo4j</groupId>
        <artifactId>neo4j</artifactId>
        <version>2.3.1</version>

Spring Data for Neo4j 的 4.0 版不支持 Neo4j 的嵌入式版本。

您需要在本地计算机上安装 Neo4j。

"SDN 4.1 will support embedded version." @Luanne
