往数据库添加数据报错，在类ssm.domain.Product中没有名为“ DepartureTime”的属性的获取器
org.springframework.web.util.Nested Servlet Exception: Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.Reflection Exception: There is no getter for property named 'DepartureTime' in 'class ssm.domain.Product'
原因：sql写错了DepartureTime应该是departureTime小写的，复制粘贴的时候没注意
