cassandra - 运行 Spring boot cassandra 项目时出现异常

Question

我通过为 web、安全、验证和 spring-boot cassandra 选择一些依赖项来下载 spring 初始化程序项目。当我尝试运行 ./gradlew bootrun 时，我在启动过程中遇到以下异常

Answer 1

com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table schema_keyspaces

正在使用的 Cassandra Java 驱动程序 Spring Data 是 2.1.9

您使用的 Cassandra 版本可能是 3.x .自 3.x 所有元数据已移至键空间 系统架构

您的问题的解决方案是:

将您的版本降级到 Cassandra 2.2.x 或 2.1.x

等待 Spring Data Cassandra 将驱动版本升级到
3.0.0

如果您不想等待，请使用 Achilles 5.2.0这是一个对象
支持 Cassandra 的映射器 3.x .注意:我是 的创建者阿喀琉斯

如果您不想等待，请使用 driver-mapper模块
附带 Cassandra Java 驱动程序
