Question

我有一个控制台模块/应用程序（不是webapp），我想使用spring-data-neo4j构建的服务模块/应用程序。

控制台应用---＆gt;使用Spring Data Neo4j模块

我使用我认为是从Neo4jConfiguration继承配置会话，会话工厂和服务器（下面粘贴的代码）的标准方法。

当控制台应用程序尝试在spring-data-neo4j服务模块中使用ogm会话时，收到错误消息：

我的配置如下：

@Configuration
@ComponentScan("nz.co.*****")
@EnableTransactionManagement
@EnableNeo4jRepositories(basePackages = "nz.co.*****")
@EnableConfigurationProperties(Neo4jProperties.class)
public class Neo4jConfig extends Neo4jConfiguration {

    private static final Logger log = LoggerFactory.getLogger(Neo4jConfig.class);

    @Inject
    private Neo4jProperties properties;

    @PostConstruct
    public void init() {
        log.debug("Initializing Neo4jConfig...");
    }

    @Bean
    @Override
    public Neo4jServer neo4jServer() {
        log.info("Initialising server connection");
        return new RemoteServer(properties.getUrl(), properties.getUsername(), properties.getPassword());
        //return new InProcessServer();
    }

    @Bean
    @Override
    public SessionFactory getSessionFactory() {
        log.info("Initialising Session Factory");
        return new SessionFactory("nz.co.*****");
    }

    @Bean
    @Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
    @Override
    public Session getSession() throws Exception {
        log.info("Initialising session-scoped Session Bean");
        return super.getSession();
    }

}

我需要做些什么才能让它发挥作用？

由于控制台应用程序中没有会话bean的概念，因此删除

来自@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)的

getSession()应该这样做。那么你甚至不需要覆盖getSession()。

如何使用Spring Data Neo4j 4创建控制台应用程序？
