   再补充下，还是要注意ApplicationModel#onDestroy的处理步骤
   是先处理了moduleModel.destroy();
   ```
   // line=206
           for (ModuleModel moduleModel : new ArrayList<>(moduleModels)) {
               moduleModel.destroy();
           }
   ```
   在这个过程中，因为处理unexportServices，最终就释放了metadataSemaphore，而此时，applicationModel.getDeployer().getState()还是是STARTED
   
   然后再处理deployer.destroy();
   ```
   // line=221
           if (deployer != null) {
               deployer.destroy();
               deployer = null;
           }
   ```
   此时，applicationModel.getDeployer().getState()才会变成STOPPING
