Spring StringTrimmerEditor使字段无效而不是禁用

Question

我正在使用Spring的registerCustomEditor修剪所有前导/尾随空格，但我不希望它在特定字段上执行，例如密码字段。

@ControllerAdvice
public class MyCustomControllerAdvice {

    @InitBinder
    public void setupDefaultInitBinder(WebDataBinder binder) {

        binder.setDisallowedFields("*password");  
        binder.registerCustomEditor(String.class, new StringTrimmerEditor(true)); 


    }
}

现在，当我使用password=[space][space]MyPassword 发布时，控制器正在获取null而不是[space][space]MyPassword

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

    PropertyEditorSupport dummyEditor = new PropertyEditorSupport() {

        @Override
        public void setAsText(String text) throws IllegalArgumentException {
            super.setValue(text);
        }

    };

    binder.registerCustomEditor(String.class, "password", dummyEditor);
}
