游戏框架（1.2.5）-是否可以在游戏框架中保留二维数组？

Question

I am working on a view where I wanna display an two dimensional arraylist Object[][] . Is it possible to persistence this out of the box when using Play Framework?

<table>
<tr>
    <td>
        #{field 'object[0][0].variable'}
            <input type="text" name="${field.name}" value="${field.value}"/>
        #{/field}
    </td>
    <td>
        #{field 'object[1][0].variable'}
            <input type="text" name="${field.name}" value="${field.value}"/>
        #{/field}
    </td>
</tr>
<tr>
    <td>
        #{field 'object[0][1].variable'}
            <input type="text" name="${field.name}" value="${field.value}"/>
        #{/field}
    </td>
    <td>
        #{field 'object[1][1].variable'}
            <input type="text" name="${field.name}" value="${field.value}"/>
        #{/field}
    </td>
</tr>
</table>

If you are using Play with JPA then no. Arrays are not persisted with JPA.

You could create your own entity and encapsulate it in a list instead.
