如何防止更新时的 Spring 验证 [英] How to prevent Spring validation on update

问题描述

我为唯一的电子邮件做了一个自定义验证注释(当用户自己注册时，程序会检查电子邮件是否已经在数据库中).

I made a custom validation annotation for unique email (When user registers itself, program checks if email is already in database).

一切正常，但是当我需要修改用户信息而不是创建新信息时，我遇到了电子邮件已在使用中"的问题

Everything works just fine, but when I need to modify user's info and not to create a new one I run into a problem that says "Email is already in use"

我能否以某种方式仅关闭 @UniqueEmail 验证(我需要其他的，如电子邮件模式和密码验证)?

Can I somehow turn off only @UniqueEmail validation(I need the others like email pattern and password validation)?

所有验证注解都在同一个用户 bean 中.

All validation annotations are in the same User bean.

谢谢.

推荐答案

我假设您正在使用 javax.validation.

首先你需要一个接口 OnUpdate:

javax.validation.groups.Default

public interface OnUpdate extends Default {}

现在您需要设置所有需要仅在UPDATE上运行的注释:

Now you need to set all the annotations that need to only run on UPDATE:

@NotNull(groups = OnUpdate.class)

现在，您已将验证分为两组，分别位于 OnUpdate 和 Default 中.运行 Default 将包括 OnUpdate 中的那些作为 OnUpdate 扩展 Default.

Now, you have divided your validations into two groups, those in OnUpdate and those in Default. Running Default will include those in OnUpdate as OnUpdate extends Default.

现在，这是有点棘手的地方 - 您需要告诉框架在每个任务上运行哪些验证.

Now, this is where it gets a little tricky - you need to tell the framework which validations to run on each task.

如果使用 JPA，您只需要设置以下属性:

If using JPA you just need to set the following property:

javax.persistence.validation.group.pre-update = com.my.package.OnUpdate
