logging - 无法加载类“org.slf4j.impl.StaticLoggerBinder”错误

Question

尽管我遵循了规则，但我收到“无法加载类”org.slf4j.impl.StaticLoggerBinder “错误：

放置一个（也是唯一一个）slf4j-nop.jar、slf4j-simple.jar、slf4j-log4j12.jar、slf4j-jdk14.jar 或 logback-classic.jar

如果有人可以帮助我，我会很高兴，在此先感谢..

这是我的依赖项：

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

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>${slf4j.version}</version>
    </dependency>

    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.15</version>

            <exclusion>

                <artifactId>jms</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

这是maven依赖树的输出：

终于找到问题了；我正在使用的 IDE - IntelliJ Idea - 需要显式显示 slf4j 依赖项以构建工件。非常感谢您的关心Ceki ..
