Ibatis执行SQL操作把SQL打印到控制台

要想让Ibatis打印SQL语句到控制台，可以在log4j.xml文件加入以下语句：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

	<appender name="IBatis" class="org.apache.log4j.ConsoleAppender">
		<layout class="org.apache.log4j.PatternLayout">
			<param name="ConversionPattern"
				value="%-4r [%t] %-5p %c %x - %m%n" />
		</layout>
		<filter class="org.apache.log4j.varia.LevelRangeFilter">
			<param name="LevelMin" value="DEBUG" />
			<param name="LevelMax" value="DEBUG" />
		</filter>
	</appender>

	<logger name="com.ibatis" additivity="true">
		<level value="DEBUG"/>
	</logger>
	<logger name="java.sql.Connection" additivity="true">
		<level value="DEBUG" />
	</logger>
	<logger name="java.sql.Statement" additivity="true">
		<level value="DEBUG" />
	</logger>
	<logger name="java.sql.PreparedStatement" additivity="true">
		<level value="DEBUG" />
		<appender-ref ref="IBatis" />
	</logger>
	<logger name="java.sql.ResultSet" additivity="true">
		<level value="DEBUG" />
		<appender-ref ref="IBatis" />
	</logger>

</log4j:configuration>
