Cassandra HeartBeat日志

Question

我在春季申请中使用cassandra。每次请求到来或连接空闲时，cassandra都会通过我的应用程序的logback打印心跳DEBUG日志。我想在调试日志中停止这些心跳记录。

2016-11-03 11:37:27,241 DEBUG [cluster1-nio-worker-2] [com.datastax.driver.core.Connection] [line : 1093 ] [] - Connection[/10.41.123.31:9042-2, inFlight=0, closed=false] heartbeat query succeeded

Answer 1

您使用的是什么记录器？

如果您使用的是log4j，则可以像这样配置调试级别：

import org.apache.log4j.PropertyConfigurator;

    private static final org.slf4j.Logger log = LoggerFactory.getLogger(Application.class);

public Application()  {
    final Properties properties = new Properties();
    properties.put("log4j.rootLogger", "INFO, A1");
    PropertyConfigurator.configure(properties);
}

然后不应再打印心跳了。
