mabatis配置log4j打印sql语句

本来配置的是log4j.properties，但是无法打印出sql语句，代码如下

log4j.rootLogger=INFO,Console,DEBUG,File
#\u5B9A\u4E49\u65E5\u5FD7\u8F93\u51FA\u76EE\u7684\u5730\u4E3A\u63A7\u5236\u53F0  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
#\u53EF\u4EE5\u7075\u6D3B\u5730\u6307\u5B9A\u65E5\u5FD7\u8F93\u51FA\u683C\u5F0F\uFF0C\u4E0B\u9762\u4E00\u884C\u662F\u6307\u5B9A\u5177\u4F53\u7684\u683C\u5F0F  
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n  

#\u6587\u4EF6\u5927\u5C0F\u5230\u8FBE\u6307\u5B9A\u5C3A\u5BF8\u7684\u65F6\u5019\u4EA7\u751F\u4E00\u4E2A\u65B0\u7684\u6587\u4EF6  
log4j.appender.File = org.apache.log4j.RollingFileAppender  
#\u6307\u5B9A\u8F93\u51FA\u76EE\u5F55  
log4j.appender.File.File = logs/ssm.log  
#\u5B9A\u4E49\u6587\u4EF6\u6700\u5927\u5927\u5C0F  
log4j.appender.File.MaxFileSize = 10MB  
# \u8F93\u51FA\u6240\u4EE5\u65E5\u5FD7\uFF0C\u5982\u679C\u6362\u6210DEBUG\u8868\u793A\u8F93\u51FADEBUG\u4EE5\u4E0A\u7EA7\u522B\u65E5\u5FD7  
log4j.appender.File.Threshold = ALL  
log4j.appender.File.layout = org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n  

log4j.logger.com.ibatis = DEBUG    
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource = DEBUG    
log4j.logger.com.ibatis.common.jdbc.ScriptRunner = DEBUG    
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate = DEBUG    
log4j.logger.java.sql.Connection = DEBUG    
log4j.logger.java.sql.Statement = DEBUG    
log4j.logger.java.sql.PreparedStatement = DEBUG    
log4j.logger.java.sql.ResultSet =DEBUG 

然后试了使用log4j.xml就能够打印

	<!-- 下面是打印 mybatis语句的配置 -->

具体原因不清楚
