好吧，我已经为这个问题绞尽脑汁好几天了，我只是不知道我错过了什么才能让它工作。我也在这里和谷歌上进行了多次搜索，但没有找到任何明显的解决方案。
当试图使用crudsiena模块保存我的第一个记录时，我得到一个"执行异常"屏幕，消息:
AbstractMethodError occured: play.modules.gae.PlayDevEnvironment.enforceApiDeadlines()Z
它说它发生了，In {module:crudsiena-2.0.2}/app/controllers/CRUD.java (around line 259)
这行是:SienaPlugin.pm().save(object);
当我创建数据模型的新对象并尝试在JUnit测试中save()它时，会发生相同的错误。
我最初开始与siena.properties中的implementation = siena.gae.GaePersistenceManager在同一文件夹中作为我的模型类，但也尝试了implementation = siena.jdbc.H2PersistanceManager尝试内存中的H2 DB，但它仍然给出了相同的错误。
play modules报告以下模块:
- crudsiena-2.0.2
- gae - 1.4
- siena-2.0.4
从我插入到单元测试中的一些调试日志输出中，似乎即使使用implementation = siena.jdbc.H2PersistanceManager, getPersistanceManager()对我的模型的实例化也返回siena.gae.GaePersistenceManager对象。
我的数据模型类如下(注意，变量和列名在这里已经混淆了):
@Table("my_model")
public class MyModel extends Model {
@Id(Generator.AUTO_INCREMENT)
public Long id;
@Column("index_alpha_numeric")
@NotNull
public String indexAlphaNumeric;
@Column("extra_index_numbers")
@Embedded
public List<String> extraNumbers;
@Column("string_value")
@NotNull
public String stringValue;
@Column("another_string")
@NotNull
public String anotherString;
@Column("another_index")
@NotNull
public Integer another_index;
//empty no-param constructor, required if explicit constructor with parameters specified
public MyModel() { }
public MyModel(String aNum, String stringVal, String string2, Integer intIndex) {
indexAlphaNumeric = aNum;
stringValue = stringVal;
anotherString = string2;
anotherIndex = intIndex;
}
public static Query<MyModel> all() {
return Model.all(MyModel.class);
}
}
我也试过删除嵌入的列表，只是想看看我是否误解了它是如何工作的，但是再一次，没有区别。
我现在想不出还有什么我需要在这个问题中包含的，但如果你需要我没有想到的额外信息，我当然很乐意帮忙。
Edit:我被要求进行堆栈跟踪，所以它在这里。这个堆栈跟踪来自JUnit测试。这个问题似乎是在GAE类中，所以我要稍微讨论一下。

您的问题显然不在模型中!这是在Play+锡耶纳IMO的配置。你没有完整的堆栈跟踪吗?
当你告诉你使用"implementation = siena.gae. "GaePersistenceManager"，它的意思是在一个siena中。属性文件吗?如果是，请删除此文件，您不需要任何siena。当使用Play作为Siena时，Siena连接到Play application.conf文件。
你能显示你的依赖关系吗?我和你同意吗?
