在工作中，排查问题时难免需要输出MyBatis真正执行的SQL及参数，需查看SQL信息，如下是一种配置方法：

log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
    <Configuration status="info">
    	<Appenders>
    		<Console name="console" target="SYSTEM_OUT">
    			<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %-5p %c{1}(%F:%L) - %m%n" />
    		</Console>
    		<RollingFile name="fixedTimeFileAppender" fileName="app/projectName.log"
    			filePattern="app/projectName.log.%d{yyyy-MM-dd}.%i.log">
    			<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %-5p %c{1}(%L) - %m%n" />
    			<Policies>
    				<TimeBasedTriggeringPolicy />
    				<SizeBasedTriggeringPolicy size="200 MB" />
    			</Policies>
    			<DefaultRolloverStrategy max="24" />
    		</RollingFile>
    		<RollingFile name="fixedTimeFileSQLAppender" fileName="app/projectName-sql.log"
    			filePattern="app/projectName-sql.log.%d{yyyy-MM-dd}.%i.log">
    			<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %-5p %c{1}(%L) - %m%n" />
    			<Policies>
    				<TimeBasedTriggeringPolicy />
    				<SizeBasedTriggeringPolicy size="200 MB" />
    			</Policies>
    			<DefaultRolloverStrategy max="24" />
    		</RollingFile>
    		
    		<Async name="async" bufferSize="512">
    			<AppenderRef ref="fixedTimeFileAppender" />
    		</Async>
    		<Async name="asyncsql" bufferSize="512" level="debug">
    			<AppenderRef ref="fixedTimeFileSQLAppender" />
    		</Async>
    	</Appenders>
    	<Loggers>
    		<Logger name="cn.bijian" level="info" additivity="false">
    			<AppenderRef ref="async" />
    		</Logger>
    		
    		<Logger name="cn.bijian.projectName.dao" level="debug" additivity="false">
    			<AppenderRef ref="asyncsql" />
    		</Logger>
    		
    		<Root level="info">
    			<AppenderRef ref="async" />
    		</Root>
    	</Loggers>
    </Configuration>
