如何通过 hibernate ogm 将 mongodb atlas 连接到 java EE 8 Framework with jpa？

Question

所以我想将一个 mongodb atlas 集群连接到一个 jpa 项目

我可以使用此 repo 连接到 mongodb 本地： https://github.com/i0712326/java-ee-hibernate-mongodb/tree/main/java-ee-09-hibernate-ogm

但是我改变了它的 persistanse.xml 文件多少才能连接到 atlas 但它没有用...... 我几乎使用了此页面中的所有属性： https://github.com/WiPeK/JavaEE-Bank/blob/5446e1c0fc87b7d4ef28e89bd3c5542de62ecaa7/shared/src/main/resources/META-INF/mongo-persistence.xml

我认为问题出在主机属性所以我用这个属性:

  <property name="hibernate.ogm.datastore.host" value="cluster0-shard-00-00.dd0ui.mongodb.net:27017,cluster0-shard-00-01.dd0ui.mongodb.net:27017,cluster0-shard-00-02.dd0ui.mongodb.net:27017 "/>

然后出现这个错误：

           Caused by: org.hibernate.HibernateException: OGM001203: Unable to find or initialize a connection to the MongoDB server
at deployment.java-ee-09-hibernate-ogm.war//org.hibernate.ogm.datastore.mongodb.impl.MongoDBDatastoreProvider.createMongoClient(MongoDBDatastoreProvider.java:133)

我用过这个属性:

       <property name="hibernate.ogm.datastore.host" value="cluster0-shard-00-00.dd0ui.mongodb.net"/>

然后这个错误显示：

            Caused by: org.hibernate.HibernateException: OGM001214: Unable to connect to MongoDB instance cluster0-shard-00-00.dd0ui.mongodb.net:27017

Answer 1

您使用的依赖项很旧。我不确定他们是否支持 MongoDB Atlas，他们不支持在配置属性中设置多个主机。这就是为什么你有 NumberFormatException.

最新的 Hibernate OGM 版本是 5.4。1.Final。除非你对使用的依赖有严格的要求，否则我会尝试使用那个：https://hibernate.org/ogm/releases/5.4/
