Unable to instantiate default tuplizer 启动tomcat 时的异常

darkpoon

　　今天在修改项目的时候,犯了一个很低级的错误, 错误很小 ,但一旦出现异常找起来就忙了半天.
　　首先我阐述一下我犯的错误, 我的项目中使用到了hibernate 3.0框架, 在进行ORM映射的时候我改动了一些属性及引用路径 而在我*.java Pojo对象原文件中我并没有对应的去改动此属性名称, 这直接导致了hbm.xml映射文件中的属性与Pojo对象中的属性不匹配,所以启动tomcat加载hibernate hbm.xml文件时找不到setter getter 访问器提供不了访问该属性的访问方法. 
　　tomcat 启动加载异常问题如下:   (注:红色字体表示异常所在)

解决问题的办法 :   把实体对象中的属性名称与hbm映射文件中 的set   name属性名称要一致
