今天用hibernate时候出现,IllegalArgumentException occurred calling getter of com.yu.model.Customer.id
根本原因是类型不匹配
在一对多的多的一方配置错误
<many-to-one name="customer" column="customer_id" class="com.yu.model.Customer"></many-to-one>
错误将customer配置成customerId, customerId是int类型,所以导致爆出参数异常
<many-to-one name="customerId" column="customer_id" class="com.yu.model.Customer"></many-to-one>
