解决方案

你使用的是mysql数据库，检查下connection.url的是否正确，我看你的异常里面显示的是URL:jdbc:log4jdbc:mysql://localhost:3306/crmdb?useUnicode=true&characterEncoding=utf-8，不应该是这样

解决方案二：

问题原因找到了，Caused by: org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set
方言没有加到spring-context里面，所以当spring初始化bin类的时候没有找到方言，就会报错
