如何即时更新 Eclipse 模板变量？

我通过扩展点添加了以下新的 Eclipse 模板。它只是添加一个示例模板testTag tag.

<!-- Add code template -->
<extension point="org.eclipse.ui.editors.templates">
   <template autoinsert="true"
             contextTypeId="html_tag"
             description="[Description] Template populated by Snippet values ***"
             id="org.eclipse.jst.jsf.ui.newHtmltag"
             name="testTag">
       <pattern>
            <![CDATA[
                <testTag style="background: ${color}"></testTag> 
            ]]>
       </pattern>
   </template>
  <resolver
     contextTypeId="html_tag"
     type="src" 
     class="TestTagTemplateVariableResolver">
  </resolver>
</extension>

What I'd cannot figure out is how to change the value of the $(color) variable at runtime. More specifically, when the user presses Ctrl + Space (or the equivalent for content-assist) and types in "testTag" and presses Enter -- instead of the "color" placeholder text, I'd like it replaced by some other text value I have in another class. How do I do this?

Java 编辑器选择不尊重为其两种上下文类型（“java”和“javadoc”）贡献的解析器，而仅识别内置解析器。

您正在使用的 html 编辑器可能有类似的限制。
