今天在spring3+structs2整合hibernate4时报如下错误，一直找不到原因：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDao': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void sy.dao.impl.UserDaoImpl.setSessionFactory(org.hibernate.SessionFactory); nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [spring-hibernate.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Error applying BeanValidation relational constraints

网上也找了，没找到解决方法，然后尝试了把pom文件中数据源和hibernate的jar包换了一个高版本，就不报错了
<!-- druid -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.17</version>
</dependency>
<!-- hibernate4 -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.2.21.Final</version>
</dependency>
我的myeclipse是2014的，可能低版本的jar包存在某些漏洞啥的，高版本的ide限制严格或者换“规矩”了把，不通过；这俩个jar包换了高版本就不报错了！
