Playframework 形式在起作用！2.5

我有一个剧本！2.2我升级到2.5的项目。但是，升级后我的数据库出现了问题，看起来是配置错误或遗漏。 看起来更改没有保存，表单也不起作用

我确实在application.conf中声明了ebeans指令：

ebean.default= ["models.*"]

然后在plugins.sbt和build.sbt中加载模块。 作为我的代码示例，我有一个设备：

@Entity
public class Device extends Model {

    @Id
    public Long id;

    @Constraints.Required
    public String name;

    @Constraints.Required
    public String ipAddress;

    @Constraints.Required
    public String uniqueId;

    @OneToMany(mappedBy="device")
    public List<Sensor> sensors = new ArrayList<>();

    @OneToMany(mappedBy="device")
    public List<Action> actions = new ArrayList<>();

    @OneToOne
    public LogItem latestError;

    @Version
    public Timestamp lastUpdate;

    public boolean debugMode;

    public boolean statusLed;

    public static Finder<Long, Device> find = new Finder<Long, Device>(
            Long.class, Device.class
    );

    public List<ValidationError> validate() {
        /*
        List<ValidationError> errors = new ArrayList<ValidationError>();
        if (User.byEmail(email) != null) {
            errors.add(new ValidationError("email", "This e-mail is already registered."));
        }
        return errors.isEmpty() ? null : errors;
        */
        return null;
    }
}

我还有一个预填充的记录，当我编辑它时，表单字段都是空的。但是，调试显示数据在那里，并且“传感器”也会出现，它是从对象本身生成的列表

所以我的配置一定有问题！2.5，但我不知道是什么。

这似乎是一个缓存问题。使用：

activator clean
activator clean-files

重建项目解决了这个问题

    @if(deviceForm.hasGlobalErrors) {
        <ul>
        @deviceForm.globalErrors.foreach { error =>
