问题描述

什么 javax.validation。* 包在Java EE，如何使用JPA 2.0使用？我想验证我与 @NotNull 标注Enity。我的JPA实现休眠：

解决方案

（普通或豆类）在您的实体使用Bean验证API，您可以很容易保证标准的验证（不为空，图案，电子邮件）。

检查出的Bean验证API神谕教程：<一href=\"http://docs.oracle.com/javaee/6/tutorial/doc/gircz.html\">http://docs.oracle.com/javaee/6/tutorial/doc/gircz.html

Hibernate也应符合本没有问题，因为它是参考实现：<一href=\"http://www.hibernate.org/subprojects/validator.html\">http://www.hibernate.org/subprojects/validator.html

解决方案

Using the Bean Validation Api you can quite easy ensure standard validation (not null, patterns, email) on your entities (or beans in common).

Check out Oracles tutorials for Bean Validation Api: http://docs.oracle.com/javaee/6/tutorial/doc/gircz.html

Also Hibernate should be no problem with this, as it is the reference implementation: http://www.hibernate.org/subprojects/validator.html

For a good introduction check Hibernates tutorial on this topic: http://docs.jboss.org/hibernate/validator/4.0.1/reference/en/html_single/
