mybatis打印sql遇到sl4j与log4j冲突问题解决.

downmovies

　　改造一个旧系统的持久层HeIbernate改为mybatis
　　这个项目由于sl4j与log4j都必须存在
　　遇到调试mybatis sql无法打印问题
　　用度娘找了很久,最后发现大家都是相互copy的,鄙视各种copy,感谢万能的google
　　下面是解决方法
　　我使用的maven为构建工具,首先加入日志依赖包

                <!-- Logging -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>${slf4j.version}</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>${slf4j.version}</version>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
　　然后修改log4j.properties

###显示SQL语句部分
# MyBatis logging configuration...
log4j.logger.cn.com.softvan.cms.dao=TRACE
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
### mybatis loggers ###
log4j.logger.com.ibatis=DEBUG,stdout
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG,stdout
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG,stdout
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG,stdout
# sql loggers

log4j.logger.java.sql.Statement=DEBUG,stdout
log4j.logger.java.sql.PreparedStatement=DEBUG,stdout
log4j.logger.java.sql.ResultSet=DEBUG,stdout


　　log4j.logger.cn.com.softvan.cms.dao=TRACE 这句一定要加 不然无法打印SQL,其它的自己看情况简化
　　cn.com.softvan.cms.dao为包路径
