有图有真相,hibernate在console里显示sql语句的参数 有图有真相~~

用ssh2做课程设计时居然用hibernate添加不进数据库。因为看不到参数，hibernate打印的sql语句里是一大堆？，让我误以为是数据传输的问题。
Hibernate: select hibernate_sequence.nextval from dual
      Hibernate: insert into BBS_User (user_username, user_password, user_authority, user_id) values (?, ?, ?, ?)
于是乎，上网猛搜，力求在console里打印出完整的SQL语句。
这得从头说起，因为在网上找到的是log4j的配置方法，我也就不创新了（些许鄙视自己下。。。）先配log4j：
加入 log4j 的jar包。
