Class CloseAwareApplicationContext

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, org.springframework.beans.factory.BeanFactory, org.springframework.beans.factory.HierarchicalBeanFactory, org.springframework.beans.factory.ListableBeanFactory, org.springframework.beans.factory.support.BeanDefinitionRegistry, org.springframework.context.ApplicationContext, org.springframework.context.ApplicationEventPublisher, org.springframework.context.ConfigurableApplicationContext, org.springframework.context.Lifecycle, org.springframework.context.MessageSource, org.springframework.core.AliasRegistry, org.springframework.core.env.EnvironmentCapable, org.springframework.core.io.ResourceLoader, org.springframework.core.io.support.ResourcePatternResolver
    public class CloseAwareApplicationContext
extends org.springframework.context.support.GenericApplicationContext
    This class has been built with very basic thread safety constructs. For our purposes the best solution would really be ReentrantReadWriteLock, but we decided not to use it due to a bug with ThreadLocal storage (Bug ID: 6625723) None of the other built-in java classes/constructs was really suitable here...

      • doClose

        protected void doClose()
        Custom implementation that tries to solve our problems with event dispatching from multiple threads when the context is closing. This method first sets "isClosing" flag to prevent any other threads from trying to start publishing events. But there might be some threads that already execute publishEvent(ApplicationEvent) method. We do not want to close Spring Context immediately then, since this might lead to different Spring-related errors. What we do: When there are any such threads, we wait for them to finish. If the threads won't finish pending calls within given timeout, we continue with closing. The timeout value is fixed as TIMEOUT_LOOP_COUNT * SLEEP_TIME milliseconds.
        Overrides:
        doClose in class org.springframework.context.support.AbstractApplicationContext
