为什么property行会报错multiple markers at this line -Attribute''type'' must be declared for element type "property"
运行后抛异常

我用的是myeclipse
------解决方案--------------------
integer
------解决方案--------------------
映射文件中描述的类型可以是java类型：
Java.lang.Integer
或是hibernate类型 ：integer
没有int
------解决方案--------------------
真有可能是integer
