##### Global logging configuration##### 在开发环境下日志级别设置成DEBUG，生产环境设置成INFO或ERRORlog4j.rootLogger=DEBUG, stdout##### mybatis日志配置log4j.logger.org.mybatis.example.BlogMapper=TRACE##### 输出到控制台，这里也可以输出到文件中，可以自己设置log4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
