Wicket 资源 - 未找到字符串？

发布于 2024-09-09 04:16:17 字数 1239 浏览 6 评论 0原文

我正在使用 wicket 的表单输入组件。我尝试将 enum 放入 DropDownMenu：

  public enum Choice { ONE, TWO, THREE }

  cz.oz.wicket.pages.form.FormPage.java
  --------------
  .add( new DropDownChoice("choice",
     Arrays.asList( Choice.values() ), new EnumChoiceRenderer() )
   )

并添加了一个属性文件：

cz.oz.wicket.pages.form.FormPage.properties
--------------
Choice.ONE = Jedna
Choice.TWO = Dvě
Choice.THREE = Tři

根据我所读到的内容，它应该可以工作。
但我得到：

java.util.MissingResourceException: Unable to find property: 'Choice.ONE'

 at org.apache.wicket.Localizer.getString(Localizer.java:344)
 at org.apache.wicket.Localizer.getString(Localizer.java:100)
 at org.apache.wicket.markup.html.form.EnumChoiceRenderer.getDisplayValue(EnumChoiceRenderer.java:82)
 at org.apache.wicket.markup.html.form.EnumChoiceRenderer.getDisplayValue(EnumChoiceRenderer.java:39)
 at org.apache.wicket.markup.html.form.AbstractChoice.appendOptionHtml(AbstractChoice.java:384)
 at org.apache.wicket.markup.html.form.AbstractChoice.onComponentTagBody(AbstractChoice.java:361)
 at org.apache.wicket.Component.renderComponent(Component.java:2619)
...

怎么了？

谢谢，

I'm playing with wicket's form input components. I tried to put an enum to a DropDownMenu:

  public enum Choice { ONE, TWO, THREE }

  cz.oz.wicket.pages.form.FormPage.java
  --------------
  .add( new DropDownChoice("choice",
     Arrays.asList( Choice.values() ), new EnumChoiceRenderer() )
   )

and added a properties file:

cz.oz.wicket.pages.form.FormPage.properties
--------------
Choice.ONE = Jedna
Choice.TWO = Dvě
Choice.THREE = Tři

According to what I've read, it should work.
But I get:

java.util.MissingResourceException: Unable to find property: 'Choice.ONE'

 at org.apache.wicket.Localizer.getString(Localizer.java:344)
 at org.apache.wicket.Localizer.getString(Localizer.java:100)
 at org.apache.wicket.markup.html.form.EnumChoiceRenderer.getDisplayValue(EnumChoiceRenderer.java:82)
 at org.apache.wicket.markup.html.form.EnumChoiceRenderer.getDisplayValue(EnumChoiceRenderer.java:39)
 at org.apache.wicket.markup.html.form.AbstractChoice.appendOptionHtml(AbstractChoice.java:384)
 at org.apache.wicket.markup.html.form.AbstractChoice.onComponentTagBody(AbstractChoice.java:361)
 at org.apache.wicket.Component.renderComponent(Component.java:2619)
...

What's wrong?

Thanks,

EnumChoiceRenderer 不知道在哪里查找属性文件。

您可以通过将页面添加为渲染器的构造函数参数来告诉它属性文件与页面关联：

  cz.oz.wicket.pages.form.FormPage.java
  --------------
  .add( new DropDownChoice("choice",
     Arrays.asList( Choice.values() ), new EnumChoiceRenderer(this) )
   )

The EnumChoiceRenderer doesn't know where to look for the properties file.

You can tell it that the properties file is associated with the page by adding the page as a constructor parameter for the renderer:

  cz.oz.wicket.pages.form.FormPage.java
  --------------
  .add( new DropDownChoice("choice",
     Arrays.asList( Choice.values() ), new EnumChoiceRenderer(this) )
   )
