问题描述
我使用 Eclipse Hibernate Tools 从我的数据库开始创建域类,并且需要添加 JPA 注释.
I use Eclipse Hibernate Tools to create domain classes starting from my database and need to add JPA annotations.
有没有办法添加注释?可能使用 reveng.xml 和逆向工程?这应该怎么做?
Is there a way to add annotations? Possibly with reveng.xml and Reverse Engineering? How should this be done?
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;
}
...
推荐答案
我个人不使用休眠工具,因为我对 Spring Roo 非常满意.然而,谷歌搜索让我想到了这一点.
I personally don't use hibernate tools, because I'm pretty happy with Spring Roo. However, google search brought me to this.
大多数情况下,mkyong.com 上有一个不错的教程.如果您转到Hibernate 透视图"并单击导出"选项卡中的代码生成配置",则会有一个生成 EJB3 注释"复选框.
As mostly there is a nice tutorial from mkyong.com. If you go to "Hibernate perspective" and click "Code generation configuration" in the "Export" tab there is a checkbox for "Generate EJB3 annotations".

这在之前的答案中得到了进一步证实.
This was further confirmed in previous answers.
