在hibernate4.3.5+struts2.0中实现从数据库中读取数据存在list中，然后取出的时候就是显现不了

// 第三个查询方法：查询属性
public List<myBook> findPersonProperty()

// 获得Hibernate Session

// 开始事务

// 以HQL语句创建Query对象.
List list = sess.createQuery("select mb.bookAuthor,mb.bookName , mb.bookPrice,mb.image "

// Query调用list()方法访问查询得到的全部属性
// 遍历查询的全部结果
