(java1.6,hibernate,mySql)
我正在尝试持久化包含字符串列表的java类.问题是,当我获取它时,我得到一个PersistentBag而不是List或PersistentList.我寻找答案或例子,但我只是更困惑.
我有一个小测试用例,我使用:
@Test
public void testFind() {
FooEntity expected = createFoo();
FooEntity actual = dao.find(expected.getId());
assertEquals(expected, actual);
assertEquals(actual, expected);
}

问题可以看作第一个assertEquals工作,而第二个
(assertEquals(actual,expected);)失败.它发生,因为List被检索为PersistentBag.
所以,你知道这里有什么不对吗?你可以帮我吗?
这是我的代码:
import java.util.ArrayList;
import java.util.List;
import javax.persistence.Column;
import javax.persistence.ElementCollection;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "EXAMPLE4_FOO")
public class FooEntity {
@Id
@GeneratedValue
@Column(name = "ID")
private int id;
@Column(name = "LIST")
@ElementCollection(fetch = FetchType.EAGER)
private List<String> strings = new ArrayList<String>();
public FooEntity() {
}
public int getId() {
