我的课

package com.logging.slf4j;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Main {
    static Logger logger = LoggerFactory.getLogger(Main.class);

    public static void main(String[] args) {
        logger.warn("Hello");
    }

}

pom.xml

        <scope>test</scope>
    </dependency>
  </dependencies>
</project>

我已经安装了所有的 Maven 依赖项。

我仍然有以下错误..

SLF4J: No SLF4J providers were found.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See https://www.slf4j.org/codes.html#noProviders for further details.

标签： java slf4j

【解决方案1】：

从依赖项中删除 <scope>test</scope>

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-reload4j</artifactId>
    <version>2.0.6</version>
    <scope>test</scope>
</dependency>

如果你想在运行代码中使用它。

范围为test 的库仅在单元测试中可用
