我无法让使用 slf4j 进行日志记录的配置正常工作。错误日志如下所示

INFO: visiting unvisited references SEVERE: log4j:ERROR A "org.apache.log4j.ConsoleAppender" object is not assignable to a "org.apache.log4j.Appender" variable.

我已经设置了以下依赖项

 <!-- Logging -->
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.5</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.5</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.7.5</version>
    </dependency>
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>

我也有hibernate和spring依赖
项我已经从依赖项中排除了commons-logging以避免任何冲突......

log4j 属性文件位于 src/main/resources 中，它位于 WEB-INF/classes/ 类路径下。

#Log to Console as STDOUT
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c %3x - %m%n
#Log to file FILE
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=logfile.log
log4j.appender.file.DatePattern='.'yyyy-MM-dd
log4j.appender.file.append=true
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c %3x - %m%n

#Root Logger
log4j.rootLogger=INFO, stdout, file

我已经尝试了几种与 slf4j-log4j12 和 slf4j-simple 的组合，它们各自独立使用，但都产生相同的错误。

注意：我注意到，如果我从 maven 依赖项中排除 jboss-logging，我不会收到 Log4j 错误。但不幸的是，jboss-logging 是一种休眠核心依赖项，没有它，应用程序将无法运行。
