Hibernate验证不起作用（它允许空值传递）

问题描述 投票：0回答：1

我试图用Hibernate验证，但@NotNull和@Size注解似乎并没有为我工作。它们允许空值，和值定义的大小通之外。每隔Hibernate验证注释也不起作用。是否有人对你知道为什么吗？看似一切正常，但它仍然不工作...

这里是我的课，观点和个XML，并且如果需要这种耐心整个项目的链接。

    @NotNull(message = "is required")

为了验证工作，Spring框架需要验证的bean存在。您需要在如下spring-mvc-demo-servlet.xml创建它 - 

    <bean id="validator" class="org.hibernate.validator.HibernateValidator" />
