我有一个实体，我正在为它创建对象。对象已创建，我可以设置值。但参考显示为null。我不明白为什么。请检查我的代码：
/* $('.nav').click(function( { */在B组我正在创建对象@Entity
@Table(name = "a_table")
public class A {
private static final long serialVersionUID = -8674959693713707364L;
/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY, generator = "IdOrGenerated")
@GenericGenerator(name = "IdOrGenerated", strategy = "foo.IdOrGenerated")
@Column(name = "id")
private Long id;
private Creator creator;
public A() {
}
public A(Creator pCreator) {
this.creator = pCreator;
}
//setters and getters for id and creator
}
当我调试并看到＆＃39; value为null。
