我用camel casing
.This 命名了类变量。这是类,这似乎是罪魁祸首。
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;
}
}
该类有几个其他变量,例如playerOneFk
,playerTwoFk
和gameLobbyFk
(hibernate 能够跟踪setter-getter
这些变量中的每个变量,但是会在列中抛出异常last_move_date
)。
我也尝试过方法名称setlastMoveDate
和getlastMoveDate
(没有运气..),属性..lastMoveDate
<property name="lastMoveDate" type="date" column="last_move_date" />
和捕获的异常
