我碰到这个问题的时候，没有数据类型不匹配的情况，也没有表达无法向action传递数据的情况，一直报这样的错误，意思就是无法使用Customer中的get方法来赋值。完整报错如下所示：
HTTP Status 500 - IllegalArgumentException occurred calling getter of cn.itcast.entity.Customer.cid; nested exception is org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of cn.itcast.entity.Customer.cid
type Exception report
message IllegalArgumentException occurred calling getter of cn.itcast.entity.Customer.cid; nested exception is org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of cn.itcast.entity.Customer.cid

后来发现是hbm.xml中写错了<many-to-one>中的class属性值。
只要class属性值错了都会报类似的错误。
如正确写法应该是这样的
<!-- 拜访记录所属用户 --> <many-to-one name="user" class="cn.itcast.entity.User" column="uvid" ></many-to-one> <!-- 拜访记录所属客户 --> <many-to-one name="customer" class="cn.itcast.entity.Customer" column="cvid"></many-to-one>
结果我写成了
<!-- 拜访记录所属用户 --> <many-to-one name="user" class="cn.itcast.entity.Customer" column="uvid" ></many-to-one> <!-- 拜访记录所属客户 --> <many-to-one name="customer" class="cn.itcast.entity.Customer" column="cvid"></many-to-one>
