替代commons-logging-1.2.jar将添加到log4j logging Framework的pom.xml文件中，以避免显示以下错误：

java.lang.IllegalStateException：ContainerBase.addChild：start：org.apache.catalina.LifecycleException：java.lang.NoClassDefFoundError：org / apache / commons / logging / LogFactory

引起：java.lang.ClassNotFoundException：org.apache.commons.logging.LogFactory

通过在/ WEB-INF / lib /文件夹中添加commons-logging-1.2.jar文件并尝试在pom.xml文件中添加commons-logging-1.2依赖关系来执行一些初步的解决步骤后，仍然没有获取任何效果很好 .

这些是Log4j.properties的详细信息：

log4j.rootLogger=INFO, Appender1, Appender2

log4j.appender.Appender1=org.apache.log4j.ConsoleAppender
log4j.appender.Appender1.layout=org.apache.log4j.PatternLayout
log4j.appender.Appender1.layout.ConversionPattern=%-7p %d [%t] %c %x - %m%n

log4j.appender.Appender2=org.apache.log4j.FileAppender
log4j.appender.Appender2.File=D:/Logs/SpringMVC.log
log4j.appender.Appender2.layout=org.apache.log4j.PatternLayout
log4j.appender.Appender2.layout.ConversionPattern=%-7p %d [%t] %c %x - %m%n

这是包含的pom.xml文件依赖项：

<log4j.version>1.6.5</log4j.version>

    以下是对pom.xml文件所做的更改，之后执行时没有错误：

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>${slf4j.version}</version>
    </dependency>

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>${slf4j.version}</version>
    </dependency>

    <!-- <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>${logback.version}</version>
    </dependency> -->

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j13</artifactId>
        <version>${slf4j.log4j13.version}</version>
    </dependency>

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>

<!-- <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
</dependency> -->

    （简短说明：如果我同时使用slf4j-api和log4j-api依赖，是否会有任何冲突，任何对此的评论都是可观的）
