How to generate domain objects with annotations using hibernate tools
提问by Dimitri Dewaele
I use Eclipse Hibernate Tools to create domain classes starting from my database and need to add JPA annotations.
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。
Is there a way to add annotations? Possibly with reveng.xml and Reverse Engineering? How should this be done?
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？
Generated domain code:
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;
}
...

I personally don't use hibernate tools, because I'm pretty happy with Spring Roo. However, google search brought me to this.
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。
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".
大多数情况下，mkyong.com 上有一个很好的教程。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。

This was further confirmed in previous answers.
这在之前的回答中得到了进一步证实。
