java - Spring Cassandra 超时查询 'SELECT * FROM system_schema.tables' 在 PT2S 后超时
问题描述
我正在使用 Spring Boot2.4.4和 Spring Data Cassandra 依赖项连接到 Cassandra 数据库。在应用程序启动期间，我收到 DriverTimeout 错误（我正在使用 VPN）。
我已经完成了所有与此类似的 Stack Overflow 问题，但没有一个对我有用。我在这里的 Spring Boot 官方页面上交叉发布了相同的问题。
我在下面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，以检查是否可以从那里获取它们。
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
以下是我在此处的帖子中建议使用的配置-
@EnableCassandraRepositories
public class CassandraConfig {
@Bean
DriverConfigLoaderBuilderCustomizer cassandraDriverCustomizer() {
return (builder) -> builder.withDuration(DefaultDriverOption.CONTROL_CONNECTION_TIMEOUT,
Duration.ofSeconds(30));
}
}
但我仍然得到同样的错误
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，例如创建自定义 CqlSessionFactoryBean 并以编程方式提供所有 DataStax 属性以覆盖 -
@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());
}
};
}
}
它没有工作同样的错误。另外，我排除了StackOverflow 上建议的Cassandra 自动配置类
我还尝试自定义自定义会话构建器，如下所示，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());
}
仍然没有运气。
不仅如此，我还添加了该application.conf文件，因为DataStax 文档建议将其放在类路径中，即使该文件正在被解析（在犯了句法错误之后，我知道它正在被读取）。它没有用。
application.conf-
datastax-java-driver {
basic.request.timeout = 10 seconds
advanced.connection.init-query-timeout = 10 seconds
advanced.control-connection.timeout = 10 seconds
}
我还切换了我的 Spring Boot 版本以2.5.0.M3查看属性文件是否有效。我已将我的项目推送到我的 GitHub 帐户。
更新
根据评论，我正在粘贴我的整个堆栈跟踪。此外，这种情况并非一直发生，有时有效，有时无效。我需要覆盖从 PT2S 到 PT10S 的超时。

解决方案
我在这里回答我自己的问题是为了完成这个问题，并让其他人知道我是如何解决这个特定问题的。
我正在使用 Spring Boot 2.4.5。当我升级到 2.3+ 版本时，我开始面临这个超时问题。
根据我对这个问题的经验，以下是我发现的。
无论您在application.propertiesor application.conf（DataStax 概念）中提供什么超时，它们都会以某种方式被弹簧引导覆盖，或者可能从 DataStax 驱动程序中选择默认值。
甚至在 Spring Boot 官方项目上也创建了一个 issue 来处理这个问题。在这里检查。后来在 2.5.0.M1 版本中得到了修复。
当我将它作为 VM 参数传递时，我的问题得到了解决。
$java -Ddatastax-java-driver.basic.request.timeout="15 seconds" application.jar
我通过了其他参数，就像advanced.control-connection.timeout我被建议在不同的论坛上使用一样，但这对我不起作用。在此处查看参考手册以获取其他配置参数。
我只在本地收到这个错误，所以我在 Eclipse VM 参数中传递了这个错误，然后我再也没有看到那个错误。
此外，如果我将此时间减少到 7-8 秒，有时我会再次看到该错误PT2S。似乎该异常消息在某处被硬编码，而与您传递的超时值无关。（这是我的观察）。
更新：解决方案 2 - 我后来想通了，我看到很多人也回答了
这个问题
DataStax 提供的实际密钥如下所示，这是有效的。
@Bean
public DriverConfigLoaderBuilderCustomizer defaultProfile(){
return builder -> builder.withString(DefaultDriverOption.METADATA_SCHEMA_REQUEST_TIMEOUT, "3 seconds").build();
}
