Kafka Streams 忽略 log4j.properties 文件

Question

我正在尝试更改 Kafka Streams 2.7.1 中的日志记录样式，但没有看到任何反应。项目结构：

log4j.properties的内容：

log4j.rootLogger=DEBUG, console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=---------%d{HH:mm:ss,SSS} %-5p %-60c %x - %m%n

在 pom.xml 我添加了下一个部门：

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.5</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-simple</artifactId>
            <version>1.6.4</version>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>2.11.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-api</artifactId>
            <version>2.11.0</version>
        </dependency>

但是应用程序的日志消息与模式不匹配（开头没有破折号）：

654 [kafka-producer-network-thread | streams-wordcount-87c688dc-7ade-4b4b-bd06-1187ffa4755a-StreamThread-1-producer] WARN org.apache.kafka.clients.NetworkClient - [Producer clientId=streams-wordcount-87c688dc-7ade-4b4b-bd06-1187ffa4755a-StreamThread-1-producer] Connection to node -1 (localhost/127.0.0.1:9092) could not be established.

为什么不起作用？

Answer 1

正如@OneCricketeer 在评论中提到的那样——我不得不修复一些依赖项的错误。而且我不得不添加以 slf4j 替换 slf4j-log4j12 才能使用 log4j.property 文件。作为最终解决方案，我在 pom.xml:

中有此依赖项

    <dependencies>
    <dependency>
        <groupId>org.apache.kafka</groupId>
        <artifactId>kafka-streams</artifactId>
        <version>2.7.1</version>
    </dependency>
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.7.25</version>
    </dependency>
</dependencies>
