Java 在项目中导入新的与cassandra相关的POM依赖项，导致运行时错误

我得到以下错误：

我已经在我的项目中导入了一个pom依赖项，新的pom依赖项inturn具有一些与cassandra相关的依赖项，如下所示：

<dependency>
            <groupId>com.datastax.cassandra</groupId>
            <artifactId>cassandra-driver-core</artifactId>
            <version>3.0.0</version>
        </dependency>   
        <dependency>
            <groupId>com.datastax.cassandra</groupId>
            <artifactId>cassandra-driver-mapping</artifactId>
            <version>3.0.0</version>
        </dependency>

com.datasax.cassandra
卡桑德拉驱动核心
3.0.0
com.datasax.cassandra
卡桑德拉驱动映射
3.0.0

卡桑德拉项目在独立环境下运行良好。有人能帮我解决这个问题吗？

您的项目正在抱怨

ClassNotFoundException:me.prettyprint.hom.CassandraPersistenceProvider

，它属于Cassandra hector客户

---

我猜您的项目使用的是不再活动的

hector core

。您必须将所有依赖项迁移到datastax的cassandra驱动程序，并删除所有与hector客户端相关的依赖项。检查它

你的卡桑德拉版本是什么？谢谢！在包含依赖项之后，它工作得非常好：）
