经过几天的错误，我希望有人能帮助我。我想通过Hibernate（5.1）将cassandra（3.9）连接到Wildfly Swarm（10.1.0）。我按照How to package Hibernate OGM applications for WildFly 10的说明将所有必需的模块添加到项目中。
>>> Project repository on Github <<<
之后，我将所有必需的依赖项添加到pom.xml：
<packaging>war</packaging>
<dependencies>
<!-- Java EE 7 dependency -->
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
<!-- WildFly Swarm Fractions -->
<dependency>
<groupId>org.hibernate.ogm</groupId>
<artifactId>hibernate-ogm-core</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate.ogm</groupId>
<artifactId>hibernate-ogm-cassandra</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-search-orm</artifactId>
</dependency>
</dependencies>
<build>
<finalName>demo</finalName>
<plugins>
<plugin>
<groupId>org.wildfly.swarm</groupId>
<artifactId>wildfly-swarm-plugin</artifactId>
<version>${version.wildfly.swarm}</version>
<executions>
<execution>
<goals>
<goal>package</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
接下来，我添加了jboss-deplyoment-structure.xml：
<jboss-deployment-structure>
<deployment>
<dependencies>
<module name="org.hibernate.ogm" slot="5.1" services="export" />
<module name="org.hibernate.ogm.cassandra" slot="5.1" services="export" />
</dependencies>
</deployment>
最后但并非最不重要的是，我添加了persistence.xml：
<persistence
xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0">
<persistence-unit name="cassandra_fhe_prd_pu" transaction-type="JTA">
<provider>org.hibernate.ogm.jpa.HibernateOgmPersistence</provider>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="jboss.as.jpa.providerModule" value="org.hibernate:5.1"/>
<property name="hibernate.transaction.jta.platform" value="JBossTS" />
<property name="hibernate.ogm.datastore.provider" value="cassandra_experimental"/>
<property name="hibernate.ogm.datastore.hosts" value="localhost"/>
<property name="hibernate.ogm.datastore.database" value="any"/>
</properties>
</persistence-unit>
我读过的每篇文章都告诉我，这就是我所要做的。但是，如果我启动应用程序，则会显示以下消息：
ERROR [org.jboss.as.controller.management-operation] (main) WFLYCTL0013: Operation ("add") failed - address: (("deployment" => "demo.war")) - failure description: {

}

"jboss.driver-demander.java:jboss/datasources/CassandraDS is missing [jboss.jdbc-driver.cassandra]"
]
}
答案 0 :(得分：0)
现在我找到了解决方案。我不知道这是否是最好的方式，但它有效：
首先，我添加了没有swarm jpa的必需分数。之后我删除了cassandra-jdbc-wrapper。现在，hibernate直接创建连接并持久化实体。我唯一想做的就是将实体类添加到持久性xml中。
工作项目被推送到存储库。我会玩群体，希望找到更好的方法。
