chickenlj opened a new issue #2158: Adaptive extension could not return the right SPI extension.
URL: https://github.com/apache/incubator-dubbo/issues/2158
 
 
   If I have an SPI configured like this:
   ```java
   @SPI("nop")
   public interface DynamicConfigurationFactory {
       @Adaptive({"key1", "key2"})
       DynamicConfiguration getDynamicConfiguration(URL url);
   }
   ```properties
   zookeeper=org.apache.dubbo.config.dynamic.support.archaius.ArchaiusDynamicConfigurationFactory
   archaius=org.apache.dubbo.config.dynamic.support.archaius.ArchaiusDynamicConfigurationFactory
   apollo=org.apache.dubbo.config.dynamic.support.apollo.ApolloDynamicConfigurationFactory
   nop=org.apache.dubbo.config.dynamic.support.nop.NopDynamicConfigurationFactory
   ```
   
   1. Give a URL:
   ```
   dubbo://0.0.0.0/xxx.DemoService?key2=zookeeper
   ```
   getAdaptiveExtension() will return the `nop` extension, but according to javadoc, it should return 'zookeeper'.
