我用的是Spring Boot 2.4.4 和spring数据连接到cassandra数据库。在应用程序启动期间，我遇到了一个drivertimeout错误（我正在使用vpn）。
我已经检查了所有类似的堆栈溢出问题，但没有一个适合我。我把同样的问题交叉贴在这里的春晚官方网页上。
我使用了下面的配置属性-

spring.data.cassandra.contact-points=xxxxxx
spring.data.cassandra.username=xxxx
spring.data.cassandra.password=xxxxx
spring.data.cassandra.keyspace-name=xxxx
spring.data.cassandra.port=9042
spring.data.cassandra.schema-action=NONE
spring.data.cassandra.local-datacenter=mydc
spring.data.cassandra.connection.connect-timeout=PT10S
spring.data.cassandra.connection.init-query-timeout=PT20S
spring.data.cassandra.request.timeout=PT10S

我还在application.properties中添加了datastax属性，以检查它们是否可以从那里获取。

datastax-java-driver.basic.request.timeout = 10 seconds
datastax-java-driver.advanced.connection.init-query-timeout = 10 seconds
datastax-java-driver.advanced.control-connection.timeout = 10 seconds

下面是我在帖子中建议的配置-

@EnableCassandraRepositories
public class CassandraConfig {
    @Bean
        DriverConfigLoaderBuilderCustomizer cassandraDriverCustomizer() {
            return (builder) -> builder.withDuration(DefaultDriverOption.CONTROL_CONNECTION_TIMEOUT,
                    Duration.ofSeconds(30));
        }
}

但我还是犯了同样的错误

Caused by: com.datastax.oss.driver.api.core.DriverTimeoutException: query 'SELECT * FROM system_schema.tables' timed out after PT2S

我还尝试了不同的方法，比如创建自定义cqlsessionfactorybean，并以编程方式提供所有datastax属性来覆盖-

@EnableCassandraRepositories
public class CassandraConfig extends AbstractCassandraConfiguration { 

    @Bean(name = "session")
        @Primary
        public CqlSessionFactoryBean cassandraSession() {
            CqlSessionFactoryBean factory = new CqlSessionFactoryBean();
            factory.setUsername(userName);
            factory.setPassword(password);
            factory.setPort(port);
            factory.setKeyspaceName(keyspaceName);
            factory.setContactPoints(contactPoints);
            factory.setLocalDatacenter(dataCenter);
            factory.setSessionBuilderConfigurer(getSessionBuilderConfigurer()); // my session builder configurer 
            return factory;
        }
    // And provided my own SessionBuilder Configurer like below

    protected SessionBuilderConfigurer getSessionBuilderConfigurer() {
        return new SessionBuilderConfigurer() {

            @Override
            public CqlSessionBuilder configure(CqlSessionBuilder cqlSessionBuilder) {
                ProgrammaticDriverConfigLoaderBuilder config = DriverConfigLoader.programmaticBuilder()
                        .withDuration(DefaultDriverOption.CONNECTION_INIT_QUERY_TIMEOUT, Duration.ofSeconds(30))
                        .withBoolean(DefaultDriverOption.RECONNECT_ON_INIT, true)
                        .withDuration(DefaultDriverOption.REQUEST_TIMEOUT, Duration.ofSeconds(30))
                        .withDuration(DefaultDriverOption.CONTROL_CONNECTION_TIMEOUT, Duration.ofSeconds(20));
                return cqlSessionBuilder.withAuthCredentials(userName, password).withConfigLoader(config.build());
            }
        };
      }
}

它不工作同样的错误。此外，我排除了cassandra自动配置类，如这里在stackoverflow上建议的那样
我还尝试自定义自定义会话生成器，如下面所示，看看是否可以工作-

@Bean
public CqlSessionBuilderCustomizer cqlSessionBuilderCustomizer() {
        return cqlSessionBuilder -> cqlSessionBuilder.withAuthCredentials(userName, password)
                .withConfigLoader(DriverConfigLoader.programmaticBuilder()
                        .withDuration(DefaultDriverOption.REQUEST_TIMEOUT, Duration.ofMillis(15000))
                        .withDuration(DefaultDriverOption.CONNECTION_INIT_QUERY_TIMEOUT, Duration.ofSeconds(30))
                        .withBoolean(DefaultDriverOption.RECONNECT_ON_INIT, true)
                        .withDuration(DefaultDriverOption.REQUEST_TIMEOUT, Duration.ofSeconds(30))
                        .withDuration(DefaultDriverOption.CONTROL_CONNECTION_TIMEOUT, Duration.ofSeconds(20)).build());
    }

还是不走运。
不仅如此，我还添加了 application.conf datastax文档建议将该文件放在类路径上，即使该文件正在被解析（在犯了语法错误之后，我知道它正在被读取）。它不起作用。
应用程序.conf-

datastax-java-driver {
 basic.request.timeout = 10 seconds
 advanced.connection.init-query-timeout = 10 seconds
 advanced.control-connection.timeout = 10 seconds
}

我还把我的春晚版本换成了 2.5.0.M3 要查看属性文件，它不起作用。我已将我的项目推送到github帐户。

更新

根据评论，我正在粘贴我的整个堆栈跟踪。而且，这种情况并不是一直发生，有时有效有时无效。我需要覆盖从pt2s到pt10s的超时。

这个 DriverTimeoutException 当驱动程序没有从协调器节点获得回复时引发。它使用基本请求超时默认值2秒：

datastax-java-driver {
  basic.request {
    timeout = 2 seconds

事实上，超时是2秒，这意味着你的覆盖没有得到拿起，但我还没有完全弄清楚为什么。
更重要的是，读或写超时异常是另一种错误，当没有足够的副本响应以满足所需的一致性级别时，就会发生这种异常——在这两种情况下，协调器都会向驱动程序返回异常。
以我的经验，一个 DriverTimeoutException 是由（a）无响应节点和/或（b）协调器过载引起的。
如果应用程序正在运行一个昂贵的查询，这可能是协调器没有及时响应的原因。在这种情况下，覆盖不起作用不是您需要解决的问题，因为用cassandra的术语来说，2秒对于应用程序请求来说是永恒的——您需要确保集群没有过载，这就是您需要解决的问题。干杯！

所以我看到了两种可能性。
这个问题最有趣的部分。。。
…是 SELECT 声明：

SELECT * FROM system_schema.tables

的键空间定义 system_schema 这是：

CREATE KEYSPACE system_schema WITH replication = {'class': 'LocalStrategy'}

这是简单拓扑还是网络拓扑？如果是这样的话，那可能是导致超时的具体原因。
这个 system_schema keyspace是新版本的cassandra（我认为是2.2+）的新功能。有没有可能你用的是旧版本？
基本上，确保 system_schema 设置了相应的默认复制。另外，请确保使用已知可用于您的cassandra版本的spring data cassandra版本。
另外，我建议您在没有spring数据的情况下尝试cassandra。我很好奇，看看这和仅仅使用纯ds java驱动程序有什么区别。
