由于 log4j 无法使用 logback

Question

嗨，我在使用 logback 和 slf4j 时遇到问题，我正在编写简单的应用程序，稍后将其打包在 jar 中，我想使用 logback 添加日志记录

我正在使用：

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.7</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.1.3</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-core</artifactId>
        <version>1.1.3</version>
    </dependency>
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-client</artifactId>
        <version>5.8.0</version>
    </dependency>

    <dependency>
        <groupId>com.mchange</groupId>
        <artifactId>c3p0</artifactId>
        <version>${c3p0.version}</version>
    </dependency>
    <dependency>
        <groupId>commons-pool</groupId>
        <artifactId>commons-pool</artifactId>
        <version>${commons.pool.version}</version>
    </dependency>
    <dependency>
        <groupId>postgresql</groupId>
        <artifactId>postgresql</artifactId>
        <version>${postgresql.version}</version>
    </dependency>
    <dependency>
        <groupId>net.sf.ehcache</groupId>
        <artifactId>ehcache</artifactId>
        <version>${ehcache.version}</version>
    </dependency>
    <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
        <version>${gson.version}</version>
    </dependency>
    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>${jedis.version}</version>
    </dependency>

在主要我有：

LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
JoranConfigurator configurator = new JoranConfigurator();
configurator.setContext(loggerContext);
configurator.doConfigure(logbackFile)

它用于在 jar 文件之外加载 logback.xml 配置

最有趣的是这个程序正在本地机器（Windows）上运行（读取 logback.xml，创建文件，写入文件）但是当我将它上传到远程服务器（linux）时我有奇怪的错误

Exception in thread "main" java.lang.ClassCastException: org.slf4j.impl.Log4jLoggerFactory cannot be cast to ch.qos.logback.classic.LoggerContext

问题是他为什么要从 org.slf4j.impl 转换 ch.qos.logback.classic.LoggerContext。Log4jLoggerFactory ??

我在任何地方都没有 log4j 的任何库...我的意思是我在整台机器上都没有它

一个附加信息：在 Windows 上我有来自 Oracle 的 Java，在 Linux 上我有 openjdk - 这可能是一个问题吗？

Answer 1

尝试消除依赖

<dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.7</version>
    </dependency>

该依赖项包含在

<dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.1.3</version>
    </dependency>

正如您在 logback-classic pom 文件中看到的那样 - http://central.maven.org/maven2/ch/qos/logback/logback-classic/1.1.3/logback-classic-1.1.3.pom

还要确保当您初始化记录器时，它是按照

private static final Logger LOG = LoggerFactory
            .getLogger(ClassName.class)
