将 apache kafka 的 log4j 桥接到 slf4j 之类的

Question

不确定为什么我无法将 log4j 消息从 apache kafka 0.8.1.1 桥接到 akka 应用程序中的 slf4j。

log4j:WARN No appenders could be found for logger (kafka.utils.VerifiableProperties).
log4j:WARN Please initialize the log4j system properly.

sbt 依赖项：

  "com.typesafe.akka" %% "akka-slf4j" % akkaVersion withSources() withJavadoc(),
  "org.apache.kafka" %% "kafka" % "0.8.1.1" exclude("javax.jms", "jms") exclude("com.sun.jdmk", "jmxtools") exclude("com.sun.jmx", "jmxri") withSources() withJavadoc(),
  "org.slf4j" % "log4j-over-slf4j" % "1.7.5",
  "ch.qos.logback" % "logback-classic" % "1.0.13",

我在 logback 中定义了根记录器并且 akka 应用程序记录正常但是我无法通过 apache kafka 的日志？无双重绑定等

我是不是忽略了什么？

感谢

Answer 1

从 kafka 依赖项中排除 log4j 解决了我的类似问题。

libraryDependencies += "org.apache.kafka" % "kafka_2.11" % "0.8.2.0" exclude("log4j", "log4j") exclude("org.slf4j","slf4j-log4j12")

sbt 依赖项

"org.apache.kafka" % "kafka_2.11" % "0.8.2.0" exclude("log4j", "log4j") exclude("org.slf4j","slf4j-log4j12"),
"org.slf4j" % "log4j-over-slf4j" % "1.7.5"
