好久了没有弄SSH框架了，刚刚整合了一下。哎呀呀，它居然给我报了错。

错误信息如下：

其实对于SSH整合经常会出现一些莫名其妙错误的信息，特别对于新手。有些人就想了，一报就这么多的错误信息，不知道该从何下手才好。

其实对于这么多的错误信息并不怕，耐心认真的看完它。看到最后你会发现它的庐山真面目的。就像上面的错误一样，最后一句错误信息“org.hibernate.PropertyNotFoundException: Could not find a getter for miLength in class " 在影射文件中没有找到miLengh属性，这下可以解开庐山真面目了吧。

错误解决：

Hibernate中影射的属性名称并不能在对应的实体类中找到。hbm.xml中的字段要跟实体中的getXX属性对应。仔细检查，修正就OK啦。
