mybatis 打印sql到控制台

1.导入jar包

<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.14</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.7</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.7</version>
</dependency>

2.log4j配置

log4j.rootLogger=DEBUG,MyeclipseConsole,ErrorLogFile,LogFile

#MyeclipseConsole
log4j.appender.MyeclipseConsole=org.apache.log4j.ConsoleAppender
log4j.appender.MyeclipseConsole.layout=org.apache.log4j.PatternLayout
log4j.appender.MyeclipseConsole.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss:SSS} %5p [SSMIntegration,%C,%L]: %m%n

##ErrorLogFile
log4j.appender.ErrorLogFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ErrorLogFile.File=${catalina.home}/logs/SSMIntegration_error.log
log4j.appender.ErrorLogFile.DatePattern='.'yyyy-MM-dd
log4j.appender.ErrorLogFile.Append=true
log4j.appender.ErrorLogFile.Threshold=error
log4j.appender.ErrorLogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.ErrorLogFile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss:SSS} %5p [SSMIntegration,%C,%L]: %m%n

##LogFile
log4j.appender.LogFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.LogFile.File=${catalina.home}/logs/SSMIntegration.log
log4j.appender.LogFile.DatePattern='.'yyyy-MM-dd
log4j.appender.LogFile.Append=true
log4j.appender.LogFile.Threshold=debug
log4j.appender.LogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.LogFile.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss\:SSS} %5p [SSMIntegration,%C,%L]\: %m%n

##SQL print to console
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,MyeclipseConsole重点是开头设置为debug级别，然后有sql print to console这块。

3.没了，注意一定要导入slf4j的两个包，否则sql语句打印不出来
