   copy from `@Activate` source code, try to use the value and group to restrict activation condition.
   ```java
   public @interface Activate {
       /**
        * Activate the current extension when one of the groups matches. The group passed into
        * {@link ExtensionLoader#getActivateExtension(URL, String, String)} will be used for matching.
        *
        * @return group names to match
        * @see ExtensionLoader#getActivateExtension(URL, String, String)
        */
       String[] group() default {};
   
       /**
        * Activate the current extension when the specified keys appear in the URL's parameters.
        * <p>
        * For example, given <code>@Activate("cache, validation")</code>, the current extension will be return only when
        * there's either <code>cache</code> or <code>validation</code> key appeared in the URL's parameters.
        * </p>
        *
        * @return URL parameter keys
        * @see ExtensionLoader#getActivateExtension(URL, String)
        * @see ExtensionLoader#getActivateExtension(URL, String, String)
        */
       String[] value() default {};
   ```
