DynamicPropertiesSource接口定义的不太好

[yinhaox]

我想使用org.apache.commons.configuration2作为动态配置源

为此我写了个简单的demo：

public class MyDynamicPropertiesSource implements DynamicPropertiesSource {
    @Override
    public MapPropertySource create(Environment environment) {
        Parameters params = new Parameters();
        File propertiesFile = new File("config.properties");
        ReloadingFileBasedConfigurationBuilder<FileBasedConfiguration> builder =
                new ReloadingFileBasedConfigurationBuilder<FileBasedConfiguration>(PropertiesConfiguration.class)
                        .configure(params.fileBased().setFile(propertiesFile));
        PeriodicReloadingTrigger trigger = new PeriodicReloadingTrigger(builder.getReloadingController(), null, 15, TimeUnit.SECONDS);
        trigger.start();

        try {
            return new ConfigurationPropertySource("local", builder.getConfiguration());
        } catch (ConfigurationException e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    public int getOrder() {
        return 0;
    }
}

ConfigurationPropertySource是configuration2提供的Spring PropertySources

但是DynamicPropertiesSource接口只支持返回MapPropertySource。

是否可以修改DynamicPropertiesSource接口里返回值的定义为PropertySource<?>
