【问题描述】：

我想使用 Cassandra appender 向 cassandra db 发送日志消息，但我遇到了下面提到的错误，

我在 docker 上使用 demo 键空间和 logs 表在 localhost 9042 上创建了独立的 cassandra

谢谢

【问题讨论】：

您可能有多个版本的 Log4j2。你能做 mvn dependency:tree 并显示结果吗？
@SimonMartinelli ı 已添加 Log4j2 相关分支

标签： cassandra log4j2 appender

【解决方案1】：

我可以看到您使用 log4j 2.8.1 和 nosql 记录器，但 spring 使用的是 2.11.2。

您应该从 spring-boot-starter-log4j2 中排除 log4j2。

【讨论】：

我已经用 log4j-cassandra (2.11.2) 更改了 log4j-nosql (2.8.1) 但我得到了上面提到的另一个例外。
调用 this.jmxReporter = JmxReporter.forRegistry(registry).inDomain(manager.clusterName + "-metrics").build();
如何禁用 JMXReporting？ com.datastax.driver.core.MetricsOptions > jmxEnabled
