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>
