问题描述
我正在使用spring-data-cassandra将应用程序从2.X升级到3.X。我正在使用Spring Boot的默认CassandraAutoConfiguration连接到Cassandra。
使用Spring数据Cassandra 2.x，为下面的Cassandra应用程序属性提供值，我可以连接到集群并使用cassandratemplate在dao中执行查询
spring.data.cassandra.contact-points=contactpoint1,contactpoint2,contactpoint3,contactpoint4
spring.data.cassandra.port=9042
spring.data.cassandra.keyspace-name=<keyspace name>
spring.data.cassandra.cluster-name=<cluster name>
spring.data.cassandra.username=<username>
spring.data.cassandra.password=<password>
spring.data.cassandra.consistency-level =一个 spring.data.cassandra.fetch-size = 100
但是对于spring data cassandra 3.x，由于应用程序属性已由于内部将datastax驱动器升级到版本4.X而更改。我在应用程序属性中提供了以下属性。
spring.data.cassandra.contact-points=contactpoint1,contactpoint4
spring.data.cassandra.port=9042
spring.data.cassandra.keyspace-name=<keyspace name>
spring.data.cassandra.session-name=<session name>
spring.data.cassandra.username=<username>
spring.data.cassandra.password=<password>
spring.data.cassandra.request.consistency=local_one
spring.data.cassandra.request.page-size=100
spring.data.cassandra.connection.init-query-timeout=2000ms
因此在按项目运行时，Spring Boot自动配置尝试连接到cassandra时，出现以下错误：-
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.data.cassandra.CassandraDataAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cassandraSession' defined in class path resource [org/springframework/boot/autoconfigure/cassandra/CassandraAutoConfiguration.class]: Bean instantiation via factory method Failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.datastax.oss.driver.api.core.CqlSession]: Factory method 'cassandraSession' threw exception; nested exception is com.datastax.oss.driver.api.core.DriverTimeoutException: query 'SELECT * FROM system.peers' timed out after PT0.5S

有人可以帮我解决这个问题吗？
我正在使用的Spring Boot版本是2.3.3.RELEASE。 Spring数据cassandra和datastax驱动程序版本是此春季启动版本附带的版本。
