如何在hibernate实体中更改列名？ [英] How to alter Column name in hibernate entity?

问题描述

我有以下hibernate实体：

I have the following hibernate entity:

@Table(name="tbl_template")
@Entity
@Audited
public class StatementTemplate {
    private Long id;
    @Column(name = "template_name")
    private String templateName;
    ...

}

我将列名从template_name更改为stmt_name

I changed the column name from template_name to stmt_name

@Column(name = "stmt_name")
private String templateName;

事实证明，而不是更改列名hibernate添加了另一个名为stmt_name的列，现在我有了template_name以及stmt_name

It turned out that the instead of changing the column name hibernate added another column named stmt_name, now I have template_name as well as stmt_name

我有以下hibernate属性设置

I have following hibernate properties set up

<prop key="hibernate.hbm2ddl.auto">update</prop>

如何将列从template_name更改为stmt_name？

How can I get the column altered from template_name to stmt_name?

推荐答案

停止你的应用程序，运行ALTER TABLE，然后再次启动应用程序？

Stopping your app, running ALTER TABLE, and starting the app again?
