成功解决：ERROR StatusLogger No log4j2 configuration file found.

报错过程

java文件中使用private static Logger logger = LogManager.getLogger(Test.class);创建了一个log对象，

在运行代码的时候出现了下列错误：

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Set system property 'org.apache.logging.log4j.simplelog.StatusLogger.level' to TRACE to show Log4j2 internal initialization logging.

翻译一下就知道，没有发现log4j2配置文件

解决

没有log4j2那就添加一个咯，命名为log4j2.xml，对应org.apache.logging.log4j.Logger

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
	<Properties>
		<property name="log_level" value="info" />
		<Property name="log_dir" value="log" />
		<property name="log_pattern"
			value="[%d{yyyy-MM-dd HH:mm:ss.SSS}] [%p] - [%t] %logger - %m%n" />
		<property name="file_name" value="test" />
		<property name="every_file_size" value="100 MB" />
	</Properties>
	<Appenders>

	</Appenders>
	<Loggers>
		<Root level="${log_level}">

	</Loggers>
</Configuration>

那么文件是有了，该放在哪里呢？

在sourceDirectory或者testSourceDirectory路径下

扩展：

log4j.properties，对应 org.apache.log4j.Logger
