java - 错误 StatusLogger Log4j2 找不到日志记录实现

Question

我正在尝试实现 log4j 2 但它一直抛出以下错误。

> ERROR StatusLogger Log4j2 could not find a logging implementation.
> Please add log4j-core to the classpath. Using SimpleLogger to log to
> the console...  
> ERROR LogExample This Will Be Printed On Error 
> FATAL LogExample This Will Be Printed On Fatal

我试过网上给出的解决方案。但它们似乎对我不起作用。

这是我要运行的代码。

package demo;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class LogExample {

    private static final Logger LOG = LogManager.getLogger(LogExample.class);

    public static void main(String[] args) {

        LOG.debug("This Will Be Printed On Debug");
        LOG.info("This Will Be Printed On Info");
        LOG.warn("This Will Be Printed On Warn");
        LOG.error("This Will Be Printed On Error");
        LOG.fatal("This Will Be Printed On Fatal");
        LOG.info("Appending string: {}.", "Hello, World");
    }

}

在 pom.xml 中添加的项目和依赖项:

感谢任何帮助。

此依赖项有助于避免 lambda 的此错误。

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-to-slf4j</artifactId>
    <version>2.8.2</version>
</dependency>
