无法使用 sessionFactory 通过 HibernateOGM 连接到 MongoDB

问题描述

我正在开发一个使用 Hibernate OGM 来处理 MongoDB 的应用程序。 sessionFactory 用于连接，配置时遇到错误。日志：

...
2020-12-21 11:09:06 INFO  DatastoreProviderInitiator:51 - OGM000016: Nosql Datastore provider: org.hibernate.ogm.datastore.mongodb.impl.MongoDBDatastoreProvider
2020-12-21 11:09:06 ERROR HibernateDataProvider:108 - org.hibernate.service.spi.ServiceException: OGM000072: Unable to configure datastore provider

类 HibernateUtil 以获取 sessionFactory：

import org.hibernate.cfg.Configuration;
import org.hibernate.SessionFactory;
import org.hibernate.ogm.cfg.OgmConfiguration;

public class HibernateUtil {
    private static SessionFactory sessionFactory;

    public static SessionFactory getSessionFactory() {
        if (sessionFactory == null) {
            Configuration configuration = new OgmConfiguration();
            //assuming the default mongodb settings
            configuration.setProperty("hibernate.ogm.datastore.provider","MONGODB");
            configuration.setProperty("hibernate.ogm.mongodb.host","127.0.0.1");
            configuration.setProperty("hibernate.ogm.mongodb.port","27017");
            configuration.setProperty("hibernate.ogm.mongodb.database","test");
            configuration.setProperty("hibernate.ogm.datastore.create__database","true");
            sessionFactory = configuration.buildSessionFactory();
        }
        return sessionFactory;
    }
}

如何解决这个问题？

解决方法

您缺少hibernate-ogm-mongodb依赖项：https://mvnrepository.com/artifact/org.hibernate.ogm/hibernate-ogm-mongodb
