我学习了 Spring 。 我对 Spring 是如何将 HTML 窗体字段的值自动与数据持有器对象的字段和设置器方法相连接的印象非常深刻。 不再有 gazillion 呼叫请求. getParamter (), 并测试每个对象的无效值 。
我想知道春天有没有像这样的东西 在相反的方向, 将信息从数据库中提取出来?
我有一个记录 有大量的田地 从我的数据层出来 通过一个哈斯马普。
Hashmap 密钥与数据库字段名称匹配, 这些密钥也与我的数据持有对象的设置相匹配。 是否有一条路 Spring 可以自动将 Hashmap 的值与数据持有对象捆绑起来, 还是我必须自己这样做?
事先感谢提供的任何资料。

您实际上是在谈论< a href=> http://static.springsource.org/spring/docs/ pext/ spring-framework-reference/html/mvc.html" rel=“nofollow” > Spring MVC 的网络框架。 您可以使用“ Spring” 框架和许多其他网络框架( 或根本没有), 因此 Spring 和 Spring MVC 是不能互换使用的术语 。
这也回答了你的问题:春季MVC是网络层的框架。让网络层了解潜在的持久性技术将是一个可怕的方法,因此直接支持数据库技术将是一个网络框架中巨大的代码嗅觉。
说, Spring 为许多不同的持久性技术提供了大量支持: < a href="http://static.springsources.org/spring/docs/current/spring-framework-reference/html/jdbc.html" rel=“nofollow” >JDBC ,
