Netflix Archaius动态配置

我正在将Hystrix集成到我现有的项目中，我想从xml文件中读取配置值，而不是使用Configuration Manager提供配置属性。 当在xml文件中更新值时，我希望在运行时更新Hystrix配置。

这是我关注的指南： https ： //github.com/Netflix/archaius/wiki/Users-Guide

到目前为止我了解到我可以使用PolledConfigurationSource和以下代码：

PolledConfigurationSource source = ... AbstractPollingScheduler scheduler = ... DynamicConfiguration configuration = new DynamicConfiguration(source, scheduler); ConfigurationManager.install(configuration); 

如何在固定的时间间隔后将PolledConfigurationSource指向xml文件以读取属性？

以下代码为我做了诀窍

 private void initializeConfiguration() { // FixedDelayPollingScheduler is initialized with default system // settings // Fixed delay in milliseconds between two reads of the configuration // URLs // archaius.fixedDelayPollingScheduler.delayMills = 60000 // Initial delay in milliseconds of reading from the configuration // source // archaius.fixedDelayPollingScheduler.initialDelayMills = 30000 AbstractPollingScheduler scheduler = new FixedDelayPollingScheduler(); // Configuration source that brings dynamic changes to the configuration // via polling PolledConfigurationSource source = new XMLPolledConfigurationSource(); // Configuration that polls a PolledConfigurationSource according to the // schedule set by a scheduler DynamicConfiguration configuration = new DynamicConfiguration(source, scheduler); ConfigurationManager.install(configuration); // Registering configuration with an MBean and will be accessible for // read and update via JConsole ConfigJMXManager.registerConfigMbean(configuration); } 

XMLPolledConfigurationSource源代码

 public class XMLPolledConfigurationSource implements PolledConfigurationSource { @SuppressWarnings("static-access") @Override public PollResult poll(boolean inital, Object checkPoint) throws Exception { PollResult pollResult = null; Map map = new HashMap<>(); // Code to read content from the resource return pollResult.createFull(map); } }

您是否尝试过根据文档设置此系统变量？ -Darchaius.configurationSource.additionalUrls=file:///apps/myapp/application.xml文档我指的是入门网页https://github.com/Netflix/archaius/wiki/Getting-Started
