Java：Elasticsearch “ERROR StatusLogger Log4j2 could not find a logging implementation"

最近使用Elasticsearch Java API，运行时遇到以下错误

ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console... Elasticsearch exception

解决方案：引用如下包，注意的是并非log4j-core

<dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-to-slf4j</artifactId>
        <version>2.11.0</version>

</dependency>

再次执行程序，遇到如下错误：

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.

解决方案：引用下面的包

<dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-simple</artifactId>
      <version>1.7.25</version>
