是否有基于注释的方法在Spring MVC 3.0中全局注册PropertyEditors？
我想知道是否有一种方法可以在Spring MVC 3.0之内全局注册PropertyEditor。在他们的文档文档中，他们展示了如何使用注释来基于每个控制器自定义bean PropertyEditor，并且 - 在我看来 - 就像我在全球范围内这样做的XML方式。所以我想知道，有没有办法，只需使用注释为所有控制器注册PropertyEditors，而无需为每个控制器执行@InitBinder方法。使用@InitBinder方法创建公共超类也是不可取的。
在Spring 3.0发布之前，有人就此主题提出了另一个问题。
