   出现的主要问题是这个？
   ```java
   java.lang.NullPointerException: null
   at org.apache.dubbo.config.ServiceConfig.doExportUrls(ServiceConfig.java:374)
   at org.apache.dubbo.config.ServiceConfig.doExport(ServiceConfig.java:361)
   at org.apache.dubbo.config.ServiceConfig.lambda$doDelayExport$0(ServiceConfig.java:243)
   at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511)
   at java.util.concurrent.FutureTask.run(FutureTask.java:266)
   at
   ```
   
   从代码分析来看 `ModuleServiceRepository repository = getScopeModel().getServiceRepository();` 并不会为空
   
   ```java
      public ModuleModel(ApplicationModel applicationModel, boolean isInternal) {
           super(applicationModel, ExtensionScope.MODULE, isInternal);
           Assert.notNull(applicationModel, "ApplicationModel can not be null");
           this.applicationModel = applicationModel;
           applicationModel.addModule(this, isInternal);
           if (LOGGER.isInfoEnabled()) {
               LOGGER.info(getDesc() + " is created");
           }
   
           initialize();
           Assert.notNull(serviceRepository, "ModuleServiceRepository can not be null");
           Assert.notNull(moduleConfigManager, "ModuleConfigManager can not be null");
           Assert.assertTrue(moduleConfigManager.isInitialized(), "ModuleConfigManager can not be initialized");
   
           // notify application check state
           ApplicationDeployer applicationDeployer = applicationModel.getDeployer();
           if (applicationDeployer != null) {
               applicationDeployer.notifyModuleChanged(this, DeployState.PENDING);
           }
       }
   ```
   
   **需要确认是否 Module 由于一些原因已经被销毁了** 
   ```java
       @Override
       protected void onDestroy() {
           // 1. remove from applicationModel
           applicationModel.removeModule(this);
   
           // 2. set stopping
           if (deployer != null) {
               deployer.preDestroy();
           }
   
           // 3. release services
           if (deployer != null) {
               deployer.postDestroy();
           }
   
           // destroy other resources
           notifyDestroy();
   
           if (serviceRepository != null) {
               serviceRepository.destroy();
               serviceRepository = null;
           }
   ```
