请帮助我更好地学习 Spring 3 MVC 的基础知识，我正在尝试了解 Spring JSR 303: Bean Validation 并且根本无法解决以下问题，我已经花了一天多的时间:(

我想要一个简单的验证在这里工作。hello.jsp 中的名称、密码和电子邮件字段不能留空，这就是目的。到目前为止，每次尝试将 hello.jsp 提交时所有字段都为空白，都会遇到以下错误

HTTP 状态 500 - 处理程序处理失败；嵌套异常是 java.lang.AbstractMethodError: org.hibernate.ejb.HibernatePersistence.getProviderUtil()Ljavax/persistence/spi/ProviderUtil;

错误堆栈：

HTTP Status 500 - Handler processing failed; nested exception is java.lang.AbstractMethodError: org.hibernate.ejb.HibernatePersistence.getProviderUtil()Ljavax/persistence/spi/ProviderUtil;


type Exception report

请让我知道我肯定错过了什么的地方。如果是 jar 兼容性问题，请提及我需要替换的 jar 的名称。

提前致谢。

您的库的版本并没有真正一起玩。例如，您使用 Hibernate ORM 3.2（实现 JPA 1.0），而 Hibernate Validator 4.2 默认使用 JPA 2（由 Hibernate ORM 3.5 实现）。请注意，您的类路径上的其他一些库看起来不正确：

  • Hibernate ORM 和 JPA API 版本不匹配
  • Hibernate Validator 引擎和 CDI 可移植扩展不匹配
  • Bean Validation API 和 Hibernate Validator 引擎不匹配
  • 两个不同版本的 slf4j API

我建议使用依赖管理工具（Ivy、Maven、Gradle）来解决这些问题。
