JSR 303 �C Bean Validation 是一个数据验证的规范。

在任何时候,当你要处理一个应用程序的业务逻辑时,必须要考虑数据校验,确保输入进来的数据从语 义上来讲是正确的。在通常的情况下,应用程序是分层的,不同的层由不同的开发人员来完成。很多时候同样的数据验证逻辑会出现在不同的层,这样就会导致代码冗余、不利于维护等问题。使用Bean Validation,将验证逻辑与相应的域模型进行绑定,能够很好的避免发生这样的问题。

Bean Validation 为 JavaBean 验证定义了相应的元数据模型和 API。缺省的元数据是 Java Annotations。在应用程序中,通过使用 Bean Validation 或是你自己定义的 constraint,例如@NotNull,@Max,@Size, 就可以确保数据模型(JavaBean)的正确性。Bean Validation 是一个运行时的数据验证框架,在验证之后验证的错误信息会被马上返回。

Hibernate Validator 是 Bean Validation 的参考实现 . Hibernate Validator 提供了 JSR 303 规范中所有内置 constraint 的实现,除此之外还有一些附加的 constraint。借助Hibernate Validator,可以很好的进行参数验证。
