在JPA和Spring中使用Hibernate验证器

问题描述

我使用Hibernate Validator 4.0.2，Spring 3.0和Hibernate 3.3.2（据我所知，它是JPA2之前的版本）作为JPA 1供应商。

我发现很容易将Validator集成到MVC层（它只是起作用），但无法看到如何将验证器自动集成到JPA entityManager（JPA 1）中。

基本上，我有一些实体将被保留，但不是来自web图层，因此尚未经过验证。我希望能够通过验证器预执行器来运行它们。

有没有一种简单的方法可以做到这一点？我知道，如果我使用的是JPA 2提供程序（如Hibernate 3.5发布时），它几乎是自动的。这就是我正在寻找的。

解决方案您需要编写一个实体监听器并触发 @PrePersist ， @PreUpdate 甚至 @PreRemove （有效的use-为此）。请参阅使用JPA 1.0进行Bean验证代码示例。

I'm using Hibernate Validator 4.0.2, Spring 3.0 and Hibernate 3.3.2 (which, as I understand it, is pre-JPA2) as a JPA 1 provider.

I've found it easy to integrate the Validator into the MVC layer (it just works) but can't see how to integrate the validator automatically into the JPA entityManager (JPA 1).

Basically, I have some entities that will be persisted but that do not come from the web layer and have therefore not already been validated. I'd like a neat way of running them through the validator pre-persist.

Is there an easy way of doing this? I'm aware that if I was using a JPA 2 provider (like Hibernate 3.5 when it is released), it'd be almost automatic. That's roughly what I'm looking for.

解决方案

You need to write an entity listener and to trigger validation on @PrePersist, @PreUpdate and even @PreRemove (there are valid use-case for that). See Bean Validation with JPA 1.0 for a code sample.
