android - ORMLite 中是否继承了 ID 字段？

Question

假设我有以下类(class):

public abstract class AHuman
{
    @DatabaseField(id = true)
    protected String login;
}

下面的两个类扩展了它:

@DatabaseTable(daoClass = UserDAO.class)
public class User extends AHuman
{
     User() {}

     @ForeignCollectionField
     private ForeignCollection<Person> friends;
}


@DatabaseTable(daoClass = PersonDAO.class)
public class Person extends AHuman
{
    Person() {}
}

当我在我的 Android 设备上编译并运行它时，出现以下错误:

java.sql.SQLException: Could not call the constructor in class class 
      com.j256.ormlite.table.CustomDaoTest$A_DaoImpl
  at com.j256.ormlite.misc.SqlExceptionUtil.create(SqlExceptionUtil.java:22)
  ...
Caused by: java.lang.reflect.InvocationTargetException
  at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
  ...
Caused by: java.lang.IllegalArgumentException: Foreign field class
>>>>      com.j256.ormlite.table.CustomDaoTest$B does not have id field  <<<<<<
  at com.j256.ormlite.field.FieldType.configDaoInformation(FieldType.java:332)

此错误源自 ForeignCollection<Person>在 User 中声明类。

显然，来自以下问题 here ，这是因为 Person 类没有在其中声明的“id”字段。

但是从抽象类继承的“id”字段不也包含在子对象中吗？

@Id 字段是继承的。也许问题在于您的构造函数不是公共(public)的(使用默认说明符)
