问题描述
kafka在运行时会不断输出debug级别的日志：
环境
kafka-streams:2.5.1
kafka-clients:2.5.1
<dependency><groupId>org.apache.kafka</groupId><artifactId>kafka-streams</artifactId><version>2.5.1</version><exclusions><exclusion><artifactId>connect-json</artifactId><groupId>org.apache.kafka</groupId></exclusion><exclusion><groupId>org.apache.kafka</groupId><artifactId>kafka-clients</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.apache.kafka</groupId><artifactId>kafka-clients</artifactId><version>2.5.1</version></dependency>
解决方法
在resources的目录下创建logback.xml文件，添加以下代码：
<configuration><appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"><encoder><pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern></encoder></appender><logger name="org.apache.kafka.clients" level="WARN" /><root level="ERROR"><appender-ref ref="STDOUT" /></root>
</configuration>
