Answer 1

如果您正在使用maven来管理依赖项，请在pom.xml中添加以下行：

<dependency>

        <groupId>commons-logging</groupId>

        <artifactId>commons-logging</artifactId>

        <version>1.1.1</version>

</dependency>

Answer 2

commons-logging-1.1.1.jar或jcl-over-slf4j-1.7.6.jar al

如果使用的是maven，请使用以下代码。

<dependency>

    <groupId>org.slf4j</groupId>

    <artifactId>jcl-over-slf4j</artifactId>

    <version>${slf4j.version}</version>

</dependency>
