请帮助我更好地学习Spring 3 MVC的基础知识,我试图学习Spring JSR303:Bean验证,但根本无法解决以下问题,我已经花了一天多的时间来解决这个问题:(
我想要一个简单的验证在这里工作。jsp中的name、password和email字段不能留空,这是我们的目标。到目前为止,每次尝试将所有字段都为空提交hello.jsp时,都会遇到以下错误

请让我知道我确实遗漏了什么地方。如果是jar兼容性问题,那么请提到我需要替换的jar的名称。
提前谢了。
您的库的版本并不能真正地一起运行。例如。您使用Hibernate ORM3.2(它实现了JPA1.0),而Hibernate Validator4.2默认情况下与JPA2(它由Hibernate ORM3.5实现)一起工作。请注意,类路径上的其他一些lib看起来并不正确:
我建议使用依赖管理工具(Ivy、Maven、Gradle)来解决这些问题。
