你可以试试在 URLMappedEdgeDispatcher 下面的代码打个断点看看，更新配置的时候， 这个 listener 是否被执行到。
```
private void loadConfigurations() {
ConcurrentCompositeConfiguration config =
(ConcurrentCompositeConfiguration) DynamicPropertyFactory
.getBackingConfigurationSource();
configurations = URLMappedConfigurationLoader.loadConfigurations(config,
KEY_MAPPING_PREFIX);
config.addConfigurationListener(event -> {
if (event.getPropertyName().startsWith(KEY_MAPPING_PREFIX)) {
LOG.info("Map rule have been changed. Reload configurations. Event="
+ event.getType());
configurations =
URLMappedConfigurationLoader.loadConfigurations(config, KEY_MAPPING_PREFIX);
}
});
}
```
