如何使用hibernate工具生成带注释的域对象

Question

我使用Eclipse Hibernate Tools从我的数据库开始创建域类,并需要添加JPA注释.

有没有办法添加注释？可能有reveng.xml和逆向工程？该怎么做？

生成的域代码:

public class Country implements java.io.Serializable {

    private long id;
    private String description;
    private String identifier;
    private String futureuse;
    private Set accounts = new HashSet(0);

    public Country() {
    }

    public Country(long id, String description, String identifier) {
        this.id = id;
        this.description = description;
        this.identifier = identifier;
    }
    ...

需要的代码:

@Entity
@Table(name = "COUNTRY")
public class Country implements java.io.Serializable {

    @Id
    @Column(name="CNTR_ID")
    private Long id;
    @Column(name="CNTR_FUTUREUSE")
    private String futureUse;
    @Column(name="CNTR_IDENTIFIER")
    private String identifier;
    @Column(name="CNTR_DESCRIPTION")
    private String description;
    private Set accounts = new HashSet(0);

    public Country() {
    }

    public Country(long id, String description, String identifier) {
        this.id = id;
        this.description = description;
        this.identifier = identifier;
    }
        ...

我个人不使用hibernate工具,因为我对Spring Roo非常满意.然而,谷歌搜索带我到这里.

大多数情况下,mkyong.com提供了一个很好的教程.如果转到"Hibernate perspective"并单击"Export"选项卡中的"Code generation configuration",则会出现"Generate EJB3 annotations"复选框.

这在以前的答案中得到进一步证实.

Hibernate工具可以生成JPA POJO吗？
