初学hibernate，遇到这样一个问题。搞了半天都不知道问题出在哪儿，结果发现是配置文件中的类型写法出了问题。
Exception in thread "main" java.lang.ExceptionInInitializerError
at hib.HibernateUtil.<clinit>(HibernateUtil.java:21)
at hib.dynamicmodel.DynamicDemo.main(DynamicDemo.java:24)
Caused by: org.hibernate.MappingException: Could not determine type for: String, for columns: [org.hibernate.mapping.Column(name)]

<property name = "name" column="name" type = "string"/>
开始我写的是 type = "String",正确的因该是上面的，type = "string"
type指的是hibernate中的类型，不是java中的String类型，必须小写。
下面是Java类型，hibernate类型 sql类型对照表：
