Answer 2

Caused by: java.lang.ClassNotFoundException: Cannot find class: cn.ccsu.crud.bean.Employee.department

Answer 3

看下server.xml文件

Answer 4

很明显不是么
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory
你的mapper.xml或者相关的数据库操作的注解错了，导致该对象无法创建，继而导致了编译失败。
