Hibernate Annotations - 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，其中两个字段不打算由 hibernate 映射(errorStatus 和 operationResultMessage).我如何(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

提前致谢.

右侧代码:

** 省略了 Getter 和 Setter！

** 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.

Use the @Transient annotation.

/* snip... */

@Transient
private Boolean errorStatus;

@Transient
private String operationResultMessage;

显然，如果您要注释的是 getter/setter 而不是字段，那么 @Transient 注释就在那里.

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