java - Spring StringTrimmerEditor 不工作

Question

正如我在这里读到的:

http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/portlet.html#portlet-ann-webdatabinder

正如我在其他问题中看到的那样，如 this one ，我在我的 Controller 中注册一个 StringTrimmerEditor，如下所示:

@Controller
public class MyController{


    @InitBinder
     public void initBinder(WebDataBinder binder) 
     {
       binder.registerCustomEditor(StringTrimmerEditor.class,new  StringTrimmerEditor(false));
     }

它编译并运行，但不起作用，它不修剪数据。我不知道我错过了什么。任何人？

谢谢

javadoc救援:

public void registerCustomEditor(Class requiredType, PropertyEditor propertyEditor)

Description copied from interface: PropertyEditorRegistry
Register the given custom property editor for all properties of the given type.

Specified by:
    registerCustomEditor in interface PropertyEditorRegistry

Parameters:
    requiredType - the type of the property
    propertyEditor - the editor to register

该类不应该是编辑器的类。它应该是您希望编辑器应用的字段的类型:String.class
