我正在尝试使用HBase处理一个介绍项目，但我遇到了SLF4J的错误。我甚至不在我的项目中使用SLF4J，但我无法理解如何解决这个问题。我在这里经历了一些其他帖子，发现应该执行从其他导入中排除SLF4J来解决此问题，但看起来我仍然遇到此问题。我正在添加错误，pom.xml，依赖关系树和我正在运行的java命令。
错误
log4j:WARN No appenders could be found for logger (org.apache.hadoop.util.Shell).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
SLF4J: slf4j-api 1.6.x (or later) is incompatible with this binding.
SLF4J: Your binding is version 1.5.5 or earlier.
SLF4J: Upgrade your binding to version 1.6.x.

您可能没有完全解决您的排除问题。即便如此，你也可以拉
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
是pom.xml中第一个声明的依赖项，因此类路径会拾取最新的jar。
Maven正在使用＆＃34;最近赢的＆＃34;策略，因此如果您将所需的依赖项作为第一个声明，则将省略所有具有匹配的groupId和artifactId的传递。
你也应该明确地定义一个绑定（写在slf4j-api下面），＆＃39;因为第二次看，它来自传递依赖的绑定，这可以解释为什么你的排除不会出现这种情况。解决你的问题。不确定您使用哪种绑定，但尝试添加类似
的内容 <dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.5</version>
</dependency>
并查看是否有帮助
答案 1 :(得分：0)
Slf4j在1.5和1.6版本之间引入了一些API不兼容性。较新的版本是向后兼容的，但如果您的应用程序使用较新的版本，而较旧的版本由maven解决，您将得到您正在遇到的问题。
对我来说最简单的解决方法是在依赖管理部分强制使用slf4j依赖版本。它相当于Master Slave的答案，只是它使用了用于此目的的机制。
看起来像这样：
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
<!--exchange this one for whatever backend you want-->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.5</version>
</dependency>
<!--if you have dependencies that use commons-logging make sure that you exclude it from them and declare this one as well-->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.7.5</version>
</dependency>
</dependencies>
</dependencyManagement>
