26.9. Using a Spring TaskExecutor for @Asynchronous
Spring provides an abstraction for executing code asynchronously, called a
TaskExecutor. The Spring-Seam integration lets you use a Spring TaskExecutor to execute immediate @Asynchronous method calls. To enable this functionality, install the SpringTaskExecutorDispatchor and provide a Spring -bean defined taskExecutor like so:
<spring:task-executor-dispatcher
task-executor="#{springThreadPoolTaskExecutor}"/>
Because a Spring
TaskExecutor does not support scheduling asynchronous events, you can provide handling with a fallback Seam Dispatcher, like so:
<!--
Install a ThreadPoolDispatcher to handle scheduled asynchronous event
-->
<core:thread-pool-dispatcher name="threadPoolDispatcher"/>
<!-- Install the SpringDispatcher as default -->
<spring:task-executor-dispatcher
task-executor="#{springThreadPoolTaskExecutor}"
schedule-dispatcher="#{threadPoolDispatcher}"/>
