Spring boot 卡桑德拉+；SpringBoot，java.lang.ClassNotFoundException:com.datastax.oss.protocol.internal.SegmentCodec

我正在尝试使用Cassandra DB创建一个Spring应用程序。但是，当我尝试运行应用程序时，出现以下错误

Caused by: java.lang.NoClassDefFoundError: com/datastax/oss/protocol/internal/SegmentCodec

Spring启动版本：2.3.4.0版本

Cassandra（弹簧启动启动器数据Cassandra）版本：3.0.4

application.yml文件：

spring:

pom.xml中存在以下依赖项（driver.version为4.9.0）

com.datastax.oss
java驱动核心
${driver.version}
com.datastax.oss
java驱动程序查询生成器
${driver.version}
com.datastax.oss
java驱动程序映射器运行时
${driver.version}

尝试添加此依赖项以获取最新的本机协议版本：

    <!-- https://mvnrepository.com/artifact/com.datastax.oss/native-protocol -->
    <dependency>
        <groupId>com.datastax.oss</groupId>
        <artifactId>native-protocol</artifactId>
        <version>1.4.11</version>
    </dependency>

com.datastax.oss
本机协议
1.4.11

Spring boot似乎链接到了导致此异常的较旧协议版本。

非常感谢！我有同样的错误

java.lang.NoClassDefFoundError:com/datastax/oss/protocol/internal/SegmentCodec

，这个答案解决了我的问题！谢谢@bswynn。在这件事上坚持了大约一个星期。你的解决方案救了我。
