休眠注释-如何从映射中排除bean的字段? [英] Hibernate Annotations - How do I exclude a bean´s field from mapping?

问题描述

我有一个包含一些字段的Bean，并且其中两个字段不打算由hibernate映射(errorStatus和operationResultMessage).如何(通过注释)告诉Hibernate我不想映射这些字段?

I´ve got a bean containing some fields, and two of them are not intended to be mapped by hibernate (errorStatus and operationResultMessage). How do I tell Hibernate (via annotations) that I don´t want to map those fields?

* bean中的映射表没有字段:errorStatus和operationResultMessage

*The mapped table in the beans does not have the fields: errorStatus and operationResultMessage

谢谢.

代码右下方:

**忽略了Gettters和Setters！

** Gettters and Setters ommited!

@Entity
@Table(name = "users")
public class AccountBean implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;

@Column(name = "name")
private String userName;

@Column(name = "email")
private String email;

@Column(name = "login")
private String login;

@Column(name = "password")
private String password;

private Boolean errorStatus;

private String operationResultMessage;

推荐答案

使用 @Transient 注释.

/* snip... */

@Transient
private Boolean errorStatus;

@Transient
private String operationResultMessage;

很明显，如果要标注的是getters/setter而不是字段，那么@Transient注释就是在这里.

Obviously, if you're annotating the getters/setters rather than the fields, that's where the @Transient annotation would go.
