如果我们在HBM.XML中定义
在创建Session的时候会告诉你Could not find a getter for xSize
经过Debug看了一下发现不是Hibernate的问题
Hibernate用的方法是
他调用的是
Introspector.decapitalize(String name);
Sun的注释说明
but in the (unusual) special case when there is more than one character and both the first and second characters are upper case, we leave it alone.
他得到getXSize这个方法名,substring[3]为XSize然后decapitalize之后不修改首位字符,就Could not find a getter for xSize了
这个是Java Bean的Spec里面规定的。方法有多种,你可以写成xsize这种全部小写,或者加"_"字符,如果你首位大写不在第二位就没问题了。
Hibernate的FAQ里面也有记录,简单提到了这个问题
I have a property named like getAFoo() / setAFoo() and Hibernate throws a PropertyNotFoundException at startup.
Use name="AFoo" from the property name, as per the JavaBeans spec.
