java - 在游戏中传递数组

Question

我在设置 boolean 值数组时遇到了一些问题。我在模型中定义了数组:

   @Entity
public class Ssr extends Model{

    @Id
    public int num;
    public boolean[] row1;

在我的 View 文件中，我正在创建表格

...

<td>Network</td>        
    @for(a <- 1 to 10){
        <td>
    @checkbox(ssrForm("row1[@a]"),'_label->None)
    </td>
    }

...

当我尝试将此值传递到下一个屏幕时，值不会保存在 ssr 对象中并且 axception 显示:

我应该使用列表而不是数组吗？

感谢您的帮助。

我找到了解决方案。如果您不需要将数组存储在数据库中，只需在变量声明中添加“transient”关键字即可。

@Entity
public class Ssr extends Model{

    @Id
    public int num;
    public transient boolean[] row1;
