使用persistence.xml连接到在Docker容器中运行的MongoDB

标签： mongodb hibernate docker jboss wildfly

我在Docker容器中的JBoss WildFly 16.0.0.Final上部署并运行了Java EE 11应用程序。

  

容器ID图像命令
  创建的状态端口
  名称867d2b0c179b gostophandle：latest“ / opt / jboss / wildfly /…”   4秒前上3秒0.0.0.0:32826->8080/tcp

我有一个也在Docker容器中运行的MongoDB实例。

  

容器ID图像命令
  创建的状态端口名称   1c064a161638 mongo“ docker-entrypoint.s…” 2   分钟前上2分钟27017 / tcp goStopHandle

这是我的“ persistence.xml”，用于连接到MongoDB的“ localhost”实例：

<persistence-unit name="goStopHandleMongoDBPersistenceUnit" transaction-type="JTA">

        <provider>org.hibernate.ogm.jpa.HibernateOgmPersistence</provider>

        <properties>

            <!-- <property name="jboss.as.jpa.providerModule" value="org.hibernate:5.2"/> -->
            <property name="jboss.as.jpa.providerModule" value="org.hibernate:5.3"/>

            <!-- <property name="wildfly.jpa.hibernate.search.module" value="org.hibernate.search.orm:5.8"/> -->
            <property name="wildfly.jpa.hibernate.search.module" value="org.hibernate.search.orm:5.10"/>

            <!-- <property name="hibernate.transaction.jta.platform" value="JBossTS"/> -->
            <!-- <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.JBossAS"/> -->
            <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform"/>
            <property name="hibernate.ogm.datastore.provider" value="org.hibernate.ogm.datastore.mongodb.impl.MongoDBDatastoreProvider"/>
            <property name="hibernate.ogm.datastore.grid_dialect" value="org.hibernate.ogm.datastore.mongodb.MongoDBDialect"/>
            <property name="hibernate.ogm.datastore.database" value="goStopHandleDB"/>
            <property name="hibernate.ogm.datastore.host" value="127.0.0.1:27017"/>
        </properties>
    </persistence-unit>

我已经跑了：

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' aea9f245ff90

并获得MongoDB容器的IP地址：

172.17.0.2

我将persistence.xml更改为使用：

<property name="hibernate.ogm.datastore.host" value="172.17.0.2:27017"/>

启动WildFly容器时，我得到：

关于如何配置“ persistence.xml”的任何建议？

2 个答案:

答案 0 :(得分：1)

类似于我尝试使用Robo 3T连接到MongoDB容器时遇到的问题。

需要公开端口：

docker run --name my-mongo -p 27017:27017 -d mongo

现在，Robo 3T和我的EAR都连接到MongoDB数据库。

答案 1 :(得分：0)

Hibernate OGM生成的MongoClient可能有问题。 解决此问题的一种方法是，确保用于客户端的配置正确无误，也许通过创建客户端并检查其连接是否正确的测试即可。 比使用OGM中的属性应用相同的配置。您可以使用前缀hibernate.ogm.mongodb.driver.*为驱动程序设置属性。有关OGM中所有可用属性的列表，我将带您进入文档：https://docs.jboss.org/hibernate/stable/ogm/reference/en-US/html_single/#_configuring_mongodb

您还可以扩展类MongoDBDatastoreProvider并覆盖方法：

  protected MongoClient createMongoClient(MongoDBConfiguration config) { ... }

然后将新类传递给属性hibernate.ogm.datastore.provider。
