做hibernate往数据库里面添加数据的小测试 jar包 实体类 主配置文件 映射文件 都按照例子写的 但是测试的时候 一直启动报这个错 不知道什么原因SLF4J: This version of SLF4J requires log4j version 1.2.12 or later. See also http://www.slf4j.org/codes.html#log4j_version
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
