我正在对遗留应用程序进行一些重构(下面包含依赖项版本信息),并从Order
提取两个相关字段到较小的类PriorityData
。这些字段仍然存在于同一个表中,但现在映射为component
。
在尝试加载Order
时,我在其中一个重新映射的字段java.lang.IllegalArgumentException: argument type mismatch
上获得了PriorityData.priority
。
通常情况下,这意味着一个简单的类型搞砸了,但我已经多次检查了一下,并且因为原因而空白。映射看起来对我来说正确,数据库类型是正确的等等。寻找解决方案,或者至少提示我应该检查什么。
更新的Order
hbm映射代码段如下:
来自Order
的访问者:
public PriorityData getPriorityData() {
return this.priorityData;
}
public void setPriorityData(PriorityData priorityData) {
this.priorityData = priorityData;
}
来自PriorityData
的访问者:
public int getPriority() {
return this.priority;
}
public void setPriority(int priority) {
this.priority = priority;
}
public Timestamp getPriorityChangeDate() {
return priorityChangeDate;
}
public void setPriorityChangeDate(Timestamp priorityChangeDate) {
this.priorityChangeDate = priorityChangeDate;
}
数据库类型声明:
PRIORITY: INTEGER
PRIORITY_CHANGE_DATE: TIMESTMP
依赖关系:Spring 3.2.8,Hibernate 3.5,DB2 9.5
