当我把这个类当作一个application运行时是正确的，输出是：
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
Hibernate: select myusertabl0_.ID as ID0_, myusertabl0_.UserName as UserName0_, myusertabl0_.Password as Password0_, myusertabl0_.Email as Email0_ from myusertable myusertabl0_ where myusertabl0_.UserName= 'qbq ' and myusertabl0_.Password= '1 '
true

你把JDBC的驱动放进你项目的lib包里了吗？
