编辑：事实证明，我不得不将vm主机中cassandra.yml文件中的rpc_address从localhost更改为vm ip地址，因此暴露给外部连接

只要您的application.yml具有以下属性，您就会添加许多Spring为您处理的样板代码：

spring:
   data:
      cassandra:
         contact-points: 
         keyspace-name: 
         username: 
         password: 
         port:

和依赖项

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-cassandra</artifactId>
</dependency>

Spring将为您配置连接，类似于RDBMS的Spring数据。

然后您可以使用Cassandra存储库查询表：

@Repository
public interface YourRepository extends CassandraRepository<Item> {
    //
}

和实体：

@Table
public class Item {
    @PrimaryKeyColumn(
      name = "id"
      type = PrimaryKeyType.CLUSTERED)
    private UUID id;
    @PrimaryKeyColumn(
      name = "key", type = PrimaryKeyType.PARTITIONED)
    private String key;
    @Column
    private String data; 
    //Getter setters
}

您spring.data.cassandra.port丢失或为空。您可以更改为以下代码，以便如果不存在该代码，则该代码将使用默认代码

@Value("${spring.data.cassandra.port: <cassandra port/9042>}")
private int port;
