如何生成使用Hibernate工具注释域对象 [英] How to generate domain objects with annotations using hibernate tools

问题描述

我使用Eclipse的Hibernate工具来创建域类从我的数据库开始，需要添加JPA注解。

有没有办法添加注释？可能与reveng.xml和逆向工程？应如何做？

生成域code：

 公共类国家实现java.io.Serializable {    私人长期身份证;
    私人字符串描述;
    私人字符串标识;
    私人字符串futureuse;
    私人设置账户=新的HashSet（0）;    公共乡村（）{
    }    公开国家（长ID，描述字符串，字符串标识符）{
        this.id = ID;
        this.description =描述;
        this.identifier =标识符;
    }
    ...
 

所需code：

  @Entity
@Table（name =COUNTRY）
公共类国家实现java.io.Serializable {    @ID
    @Column（NAME =CNTR_ID）
    私人长期身份证;
    @Column（NAME =CNTR_FUTUREUSE）
    私人字符串futureUse;
    @Column（NAME =CNTR_IDENTIFIER）
    私人字符串标识;
    @Column（NAME =CNTR_DESCRIPTION）
    私人字符串描述;
    私人设置账户=新的HashSet（0）;    公共乡村（）{
    }    公开国家（长ID，描述字符串，字符串标识符）{
        this.id = ID;
        this.description =描述;
        this.identifier =标识符;
    }
        ...
 

解决方案

我个人不使用休眠的工具，因为我是pretty满意的Spring Roo。然而，谷歌搜索给我带来了这一点。

由于大多有来自mkyong.com一个很好的教程。如果你走在导出选项卡休眠视角，然后点击code一代配置有生成EJB3注释复选框。

这是进一步previous答案证实。

可以冬眠的工具生成JPA POJO？

I use Eclipse Hibernate Tools to create domain classes starting from my database and need to add JPA annotations.

Is there a way to add annotations? Possibly with reveng.xml and Reverse Engineering? How should this be done?

Generated domain code:

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;
    }
    ...

Needed code:

@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;
    }
        ...

解决方案

I personally don't use hibernate tools, because I'm pretty happy with Spring Roo. However, google search brought me to this.

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".

This was further confirmed in previous answers.

can hibernate tool generate jpa pojo?
