Log4j cassandra appender异常

我想使用下面提到的cassandra appender buıam GetInd错误向cassandra db发送日志消息

我已经在docker上创建了独立的cassandra，在localhost 9042上使用demo键空间和logs表

我已经更改了log4j nosql与log4j cassandra的依赖关系，并且我已经为cassandra驱动程序核心添加了排除，用于度量核心下面提到的异常更改

<dependency>
    <groupId>com.datastax.cassandra</groupId>
    <artifactId>cassandra-driver-core</artifactId>
    <exclusions>
        <exclusion>
            <groupId>io.dropwizard.metrics</groupId>

    </exclusions>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-cassandra</artifactId>
</dependency>

我已经添加了指标jmx站点的依赖性指南
但应用程序在生成记录器时再次抛出下面的异常

<dependency>
  <groupId>io.dropwizard.metrics</groupId>
  <artifactId>metrics-jmx</artifactId>
  <version>4.0.5</version>
</dependency>

io.dropwizard.metrics
度量jmx
4.0.5

线程“main”java.lang.NoClassDefFoundError中的异常：com/codahale/metrics/JmxReporter 位于com.datastax.driver.core.Metrics.（Metrics.java:146） 位于com.datastax.driver.core.Cluster$Manager.init（Cluster.java:1501） 位于com.datastax.driver.core.Cluster.init（Cluster.java:208） 位于com.datastax.driver.core.Cluster.connectAsync（Cluster.java:376） 位于com.datastax.driver.core.Cluster.connect（Cluster.java:332） 位于org.apache.logging.log4j.cassandra.CassandraManager.startupInternal（CassandraManager.java:74） 位于org.apache.logging.log4j.core.appender.db.AbstractDatabaseManager.startup（AbstractDatabaseManager.java:222） 位于org.apache.logging.log4j.core.appender.db.AbstractDatabaseAppender.start（AbstractDatabaseAppender.java:172） 位于org.apache.logging.log4j.core.config.AbstractConfiguration.start（AbstractConfiguration.java:266） 位于org.apache.logging.log4j.core.LoggerContext.setConfiguration（LoggerContext.java:548） 位于org.apache.logging.log4j.core.LoggerContext.reconfigure（LoggerContext.java:620） 位于org.apache.logging.log4j.core.LoggerContext.reconfigure（LoggerContext.java:637） 位于org.apache.logging.log4j.core.LoggerContext.start（LoggerContext.java:231） 位于org.apache.logging.log4j.core.async.AsyncLoggerContext.start（AsyncLoggerContext.java:76） 位于org.apache.logging.log4j.core.impl.Log4jContextFactory.getContext（Log4jContextFactory.java:153） 位于org.apache.logging.log4j.core.impl.Log4jContextFactory.getContext（Log4jContextFactory.java:45） 位于org.apache.logging.log4j.LogManager.getContext（LogManager.java:194） 位于org.apache.logging.log4j.LogManager.getLogger（LogManager.java:581） 位于com.example.demo.Application（Application.java:13） 原因：java.lang.ClassNotFoundException:com.codahale.metrics.JmxReporter 位于java.net.URLClassLoader.findClass（URLClassLoader.java:382） 位于java.lang.ClassLoader.loadClass（ClassLoader.java:424） 位于sun.misc.Launcher$AppClassLoader.loadClass（Launcher.java:349） 位于java.lang.ClassLoader.loadClass（ClassLoader.java:357）

谢谢

我可以看到，您在nosql记录器中使用的是log4j 2.8.1，而spring使用的是2.11.2

---

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

您可能有多个版本的log4j2。你能做mvn dependency:tree并显示结果吗？@SimonMartinelliı添加了Log4j2相关分支我将log4j nosql（2.8.1）更改为log4j cassandra（2.11.2）但是，我得到了上面提到的另一个异常。调用this.jmxReporter=jmxReporter.forRegistry（registry）.inDomain（manager.clusterName+“-Metrics”）.build（）时在com.datastax.driver.core.Metrics中引起的问题；如何禁用JMXReporting？com.datastax.driver.core.MetricsOptions>jmxEnabled
