Spring 使用HibernateTemplate持久化CGLIB代理实体
我几乎找遍了所有地方，但似乎没有人有这个问题。 我有SpringMVC应用程序。 有一个UserImpl实体，它在上下文配置文件中声明为请求范围的bean，并由UsersController引用。UsersController引用的UserImpl对象实际上是一个CGLib代理（为什么？）。现在，当我第一次尝试使用HibernateTemplate持久化这样的代理对象时，我遇到了以下错误： org.hibernate.MappingException:未知实体： main.mvc.model.hibernate.UserImpl$$enhancerbyglib$$9ac49631 经过一番搜索，我发现了如下内容： org.springframework.orm.hibernate3.support.ScopedBeanInterceptor 这解决了问题。现在我没有得到MappingException，实体被持久化了，但是。。。数据库记录中的每个字段都为空。有什么问题吗 注: 当我硬编码UserImpl实例并使用UserServiceImpl持久化它时，一切都正常 上下文配置的一部分：Spring 使用HibernateTemplate持久化CGLIB代理实体,spring,hibernate,proxy,cglib,Spring,Hibernate,Proxy,Cglib,我几乎找遍了所有地方，但似乎没有人有这个问题。 我有SpringMVC应用程序。 有一个UserImpl实体，它在上下文配置文件中声明为请求范围的bean，并由UsersController引用。UsersController引用的UserImpl对象实际上是一个CGLib代理（为什么？）。现在，当我第一次尝试使用HibernateTemplate持久化这样的代理对象时，我遇到了以下错误： org.hibernate.MappingException:未知实体： main.mvc.model.h

公共类UserServiceImpl扩展了HibernateDaoSupport实现UserService{
专用密码编码器；
私人盐源盐源；
@注入
public UserServiceImpl（SessionFactory SessionFactory、PasswordEncoder PasswordEncoder、SaltSource SaltSource）{
超级（）；
设置会话工厂（会话工厂）；
设置密码编码器（密码编码器）；
设置盐源（盐源）；
}
公共作废保存（用户）{
Date creationTime=新日期（）；
user.setCreationDate（creationTime）；
user.setLastModified（creationTime）；
列表角色=新建LinkedList（）；
roles.add（Role.Role\u用户）；
user.setRoles（角色）；
Logger.getLogger（getClass（））.info（用户）；
getHibernateTemplate（）.save（用户）；

好的，我已经添加了一些AOP magic add输出，在ScoppedBeanInterceptor中处理实体对象时会发生什么。它完好无损。尽管Hibernate的BasicBinder将空值绑定到SQL语句。有什么帮助吗 日志：
