Class MessageProviderCacheCleanupExecutor

java.lang.Object

org.vaadin.spring.i18n.MessageProviderCacheCleanupExecutor

public class MessageProviderCacheCleanupExecutor
extends Object

This class will start up a thread that will invoke CompositeMessageSource.clearMessageProviderCaches() on a regular interval if enabled (by default it is disabled). This feature is intended to be used during development, together with a tool such as JRebel, to prevent time consuming application restarts while tweaking the translations.

To enable, specify the interval in seconds in the environment property "vaadin4spring.i18n.message-provider-cache.cleanup-interval-seconds" and disable the message format cache of the CompositeMessageSource.
