eclipse名为“ID_GENERATOR”的重复生成器在此持久性单元中定义 [英] eclipse Duplicate generator named "ID_GENERATOR" defined in this persistence unit

问题描述

我目前遇到这个我没有迁移到eclipse-jee-kepler的问题。我有：

I'm currently having this issue which I don't have before I migrated to eclipse-jee-kepler. What I have:

我有2个班级，基础和延伸课程：

I have 2 classes, base and the extending class:

public abstract class BaseEntity implements Serializable {
    @Id
    @GeneratedValue(generator = "ID_GENERATOR")
    @Column(name = "ID")
    private Long id;
}

@Entity
@Table(name = "CUSTOMER")
@SequenceGenerator(name = "ID_GENERATOR", sequenceName = "CUSTOMER_SEQ")
public class Customer extends BaseEntity {
}

在我没有此验证错误之前但现在日食正在扔它。我可以编译，构建和部署成功，但错误标记使得很难确定编译错误，当你真的有一个。

Before I don't have this validation error but now eclipse is throwing it. I can compile, build and deploy successfully but the error marker is making it hard to pinpoint the compile errors when you really have one.

错误似乎很明显，这是因为我在所有扩展类上都有ID_GENERATOR。我的问题：
1.）我可以忽略这个错误吗？
2.）任何工作？可能使用不同的方法。

The error seems obvious, it's because I have ID_GENERATOR on all the extending classes. My question: 1.) Can I ignore this error? 2.) Any work around? Possibly using a different approach.

推荐答案

我想到了这个问题，这是一个日常的JPA验证设置。要禁用：

I figured the problem, it was more of an eclipse JPA validation setting. To disable:

1. 选择窗口»首选项


2. 展开 Java持久性»JPA»错误/警告


3. 点击查询和生成器


4. 设置将重复的生成器定义为忽略


5. 单击确定应用更改并关闭对话框

1. Select Window » Preferences
2. Expand Java Persistence » JPA » Errors/Warnings
3. Click Queries and generators
4. Set Duplicate generator defined to: Ignore
5. Click OK to apply changes and close the dialog

您还可以将值设置为警告而不是忽略。

You can also set the value to Warning instead of Ignore.
