slf4j& log4j2 maven设置查询 [英] slf4j & log4j2 maven setup query

问题描述

我在我的项目中使用log4j2和slf4j&使用maven进行构建。我正在使用以下pom文件（仅显示相关的依赖项）但我收到下面复制的错误与此pom文件 - 任何想法我需要添加/删除以使其工作。我已经访问了错误中的url以及log4j2依赖项页面，因此请不要只指向响应中的URL。

I am using log4j2 and slf4j in my project & using maven for the build. I am using the following pom file (releveant dependencies shown only) but I am getting the error copied below with this pom file - any idea what I need to add/remove to get this to work. I have already visited the url in the error as well as the log4j2 dependencies page so please do not just point to URLs in your response.

消息：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

pom file

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <slf4j.version>1.7.7</slf4j.version>
</properties>

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

        <artifactId>disruptor</artifactId>

        <artifactId>log4j-core</artifactId>

     </dependency>

更新：
我向我的pom添加了以下依赖项文件，我在我的mavenrepository中看到了jar - 虽然我在运行mvn clean / install时仍然看到相同的消息

Update: I added the following dependency to my pom file and I see the jar in my mavenrepository - though I still see the same message when I run mvn clean/install

    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-slf4j-impl</artifactId>
        <version>2.0.1</version>
    </dependency>

推荐答案

您好像丢失了pom文件中的以下内容。

You seem to be missing the following from your pom file.

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-slf4j-impl</artifactId>
    <version>2.0.1</version>
</dependency>
