如何在控制台打印出mybatis sql语句日志

1.首先配置 log4j日志文件 

#mybatis日志范围
log4j.logger.com.nes=TRACE
#ibatis配置
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.org.mybatis=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  

2.导入依赖日志包 log4j

<!-- SLFJ 可依赖到log4j-->
