ERROR StatusLogger Log4j2 could not find a logging implementation.

产生错误的原因
struts2 出现这个错误错误，是因为包没有加载全

解决方法
在pom.xml文件中运行如下代码

<dependency>
		    <groupId>org.apache.logging.log4j</groupId>
		    <artifactId>log4j-core</artifactId>
		    <version>2.10.0</version>
		</dependency>
		<dependency>
		    <groupId>org.apache.logging.log4j</groupId>
		    <artifactId>log4j-api</artifactId>
		    <version>2.10.0</version>
	    </dependency>
	</dependencies>

再次运行测试，如果出现如下错误就需要新建一个log4j2.xml文件了

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Set system property 'log4j2.debug' to show Log4j2 internal initialization logging.
