google group threads上提出了这方面的建议。 据认为,最好的方法是依靠违约构造来对田地的违约值进行投机。

我对此进行了测试,并做了罚款。 我的检验标准是建立一个简单的模式类别,为其中一个领域设定一个违约值,然后利用缺席的CRUD环境。

package models;

@javax.persistence.Entity
public class Person extends play.db.jpa.Model {

    public int age;
    public String name;

    public Person() {
        age = 18;
    }
}

如果我去读到CRUD屏幕,年龄就显示为18岁。
