我有这个项目,我正在使用hibernate,gwt,JPA,Tomcat和spring。无论如何,我一直试图解决这个错误没有成功。这是我的错误:
log4j:WARN No appenders could be found for logger(org.hibernate.cfg.annotations.Version).
Please initialize the log4j system properly.

答案 0 :(得分:0)
您需要将hibernate-validator添加到项目中。
http://www.hibernate.org/subprojects/validator/download
如果要删除log4j警告,则应添加log4j.properties文件。
删除它,不需要它,几乎肯定会导致错误。如果您看到我以前的评论,我建议删除它。这只是接口绑定而不是jsr303验证api的实现代码。 Hibernate首先看到这一点,而不是使用hibernate-validator库进行验证。
