• Hibernate 使用log4j日志记录


    日志记录使程序员能够将日志详细信息永久写入文件。这是我们以后在开发当中非常重要的一步。

    Hibernate使用log4j日志记录,我们需要以下几个步骤:

    1.导入jar包:

      (1)这是hibernate下载后自带的有,导入即可。

      (2):下载地址:http://logging.apache.org/log4j/1.2/download.html

      (3):下载地址:https://www.slf4j.org/download.html

    2.配置文件,log4j.properties.在下载的hibernate中你搜索这个文件复制到项目classpath中就可以,就是与hibernate.cfg.xml同级目录

    log4j.logger.org.hibernate.cache trace
    log4j.logger.org.hibernate.stat trace

    这样我们就可以看到控制台日志文件了。
