我用camel casing
命名了这个类变量。这是类,它似乎是罪魁祸首。
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import java.sql.Date;
public class GameBoard
{
@Temporal(TemporalType.DATE)
private Date lastMoveDate;
/**
* @return the lastMoveDate
*/
public Date getLastMoveDate() {
return lastMoveDate;
}
/**
* @param lastMoveDate the lastMoveDate to set
*/
public void setLastMoveDate(Date lastMoveDate) {
this.lastMoveDate = lastMoveDate;
}
}
该类还有其他几个变量,例如playerOneFk
,playerTwoFk
和gameLobbyFk
(hibernate能够跟踪这些变量上的每个setter-getter
,但是会抛出异常last_move_date
列。)
我还尝试了方法名称setlastMoveDate
和getlastMoveDate
(没有运气..),lastMoveDate
的属性..
<property name="lastMoveDate" type="date" column="last_move_date" />
捕获的异常

答案 0 :(得分:2)
在Hibernate中,属性类型“date”映射到java.sql.Date。
如果您使用的是java.util.Date,则需要将属性类型设置为“timestamp”。
现在使用“date”将导致它查找在java.sql.Date上运行的getter / setter,它将无法找到它。
见Hibernate basic type reference(6.1.1.12和6.1.1.14)。
编辑:解决一些命名约定问题:
Hibernate遵循标准的bean命名约定:

<property name="LastMoveDate" type="date" column="last_move_date" />
应该有用......
