spring-cloud-starter-hystrix 和 spring-cloud-starter-archaius 集成的内存泄漏问题 [英] Memory Leak Issue with spring-cloud-starter-hystrix and spring-cloud-starter-archaius integration

问题描述

我们将 spring-cloud-starter-hystrix 与 spring-cloud-starter-archaius 一起使用，一旦战争取消部署，我们将无法停止 archaius 的 poolingconfigurationSource 线程.但是 spring-cloud-starter-archaius 在没有 hystrix 的情况下工作正常，一旦战争取消部署，线程就会停止.

We are using spring-cloud-starter-hystrix with spring-cloud-starter-archaius where we are unable to stop the poolingconfigurationSource thread of archaius once the war is un-deployed. But spring-cloud-starter-archaius is working fine without hystrix and thread is stopped once war is un-deployed.

推荐答案

**Issue resolved permanently.**

**There are 2 approach :**
1) Create ContextListener in Servlet and in destroy method , copy below code.

2) If you are using Histrix + Spring Boot + Archaius then on main spring application java file , copy below code in method annonated with @PreDestory annotations.

    **Solution :**

    try {
    if (ConfigurationManager.getConfigInstance() instanceof DynamicConfiguration) {
    DynamicConfiguration config = (DynamicConfiguration) ConfigurationManager.getConfigInstance();
    config.stopLoading();
    } else if (ConfigurationManager.getConfigInstance() instanceof ConcurrentCompositeConfiguration) {
    ConcurrentCompositeConfiguration configInst = (ConcurrentCompositeConfiguration) ConfigurationManager
    .getConfigInstance();
    List<AbstractConfiguration> configs = configInst.getConfigurations();
    if (configs != null) {
    for (AbstractConfiguration config : configs) {
    if (config instanceof DynamicConfiguration) {
    ((DynamicConfiguration) config).stopLoading();
    break;
    }
    }
    }
    }
    } catch (Exception e) {
    e.printStackTrace();
    }
