2.4.4
和Spring Data Cassandra依赖项连接到Cassandra数据库。在应用程序启动期间,我遇到了DriverTimeout错误(我正在使用VPN)。我已经查看了所有类似的Stack Overflow问题,但没有一个适用于我。我已经在Spring Boot 官方页面上发布了相同的问题。
我使用了以下配置属性 -
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
以下是我在这里建议的配置 -
@EnableCassandraRepositories
public class CassandraConfig {
@Bean
DriverConfigLoaderBuilderCustomizer cassandraDriverCustomizer() {
return (builder) -> builder.withDuration(DefaultDriverOption.CONTROL_CONNECTION_TIMEOUT,
Duration.ofSeconds(30));
}
}
但我仍然收到相同的错误信息
Caused by: com.datastax.oss.driver.api.core.DriverTimeoutException: query 'SELECT * FROM system_schema.tables' timed out after PT2S
我也尝试了不同的方法,比如创建自定义的CqlSessionFactoryBean并以编程方式提供所有DataStax属性来进行覆盖 -
@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());
}
};
}
}
它没有工作,出现了相同的错误。此外,我像这里在StackOverflow上建议的那样,排除了Cassandra自动配置类。
我还尝试自定义会话构建器,如下所示,以查看是否可以工作:
@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());
}
还是没有运气。
不仅如此,我还按照DataStax文档建议的将application.conf
文件添加到类路径中,尽管该文件正在被解析(在犯了语法错误后我知道它正在被读取)。但是它没有起作用。
application.conf-
datastax-java-driver {
basic.request.timeout = 10 seconds
advanced.connection.init-query-timeout = 10 seconds
advanced.control-connection.timeout = 10 seconds
}
我还将Spring Boot版本切换到2.5.0.M3
,以查看属性文件是否起作用。我已将我的项目推送到我的GitHub帐户。
更新
根据评论,我将整个堆栈跟踪粘贴在此处。此外,这并不总是发生,有时它有效,有时它无效。我需要将超时从PT2S覆盖为PT10S或其他值。

spring.data.cassandra.connection.init-query-timeout=PT20S
,但错误消息中提到了PT2S
。这是打字错误吗?你排除了网络问题吗(例如使用nc
或类似工具检查连接性)?在超时发生之前,我建议你在应用程序运行时检查netstat -nt
输出。 - Tasos P.spring.data.cassandra.*
属性都不会产生任何效果。 - Andy Wilkinson
