Spring 上下文刷新，组件未在集成测试中正确重新加载

Question

我正在尝试编写一个用于 failsafe 的小型库。

基本上，我将注册的断路器放入一个散列图中，该散列图由 class 保存，并用 @Component 注释。

当运行通过一个运行命令进行多个集成测试时，我面临的问题是 @PostConstruct Beans 的方法被 ApplicationContext.refresh() 重新调用，其中哈希图仍然保留对先前引用对象的引用。因此地图抛出 IllegalArgumentException 因为我喜欢这样设计它。

尽管如此，我想我只是错过了一些在调用刷新之前清理地图的东西。

这里有人可以给我提示吗？该项目可以在 here.

中找到

需要清理的Bean是this。

最佳

更新

这是堆栈跟踪，您可以在其中查看调用流程：

我也在本地调整了CircuitBreakerRegistry，使其实现了DisposableBean，但实际上并没有什么区别。

Answer 1

其实我才知道是什么原因导致的，我注册CircuitBreaker的地图是static。

@Component
public class CircuitBreakerRegistry {

    private static final Map<String, CircuitBreaker> concurrentBreakerMap = new ConcurrentHashMap<String, CircuitBreaker>();
 //More code here...
}
