如何使用休眠工具生成带注释的域对象 [英] How to generate domain objects with annotations using hibernate tools

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.
