问如果惰性集合已反序列化，则无法使用这些集合。

EN

我在我的项目中使用ORM，而且我遇到了这样一种情况:由putExtra执行步骤-- Person对象的意图，它有一个电子邮件对象集合，但是当我试图读取这个集合(类似于LazyLoad (急切=假))时，下面遵循了用于检索电子邮件集合的模型和代码：

public class Pessoa implements Serializable{

    @DatabaseField(generatedId=true)
    private int id;

        ...

    @ForeignCollectionField(eager=false)
    private Collection<Email> emails;

        ...
}
public class Email implements Serializable{

    @DatabaseField(generatedId=true)
    private int id;

    ...

    @DatabaseField(foreign=true)
    private Pessoa pessoa;

       ...
}

检索收藏：

if(getIntent().hasExtra("Pessoa")){
       pessoa = (Pessoa) getIntent().getSerializableExtra("Pessoa");

Iterator<Endereco> iterator = pessoa.getEnderecos().iterator();
while(iterator.hasNext()){
        Endereco end = iterator.next();
        Log.e("ENDERECO",end.getLogradouro());
}

我得到以下错误：

这个错误清楚地说明了问题是什么，但是它有另一种方法将Person对象传递给另一个意图，并且它适用于lite ORM？

谢谢!
