Interface AsyncConfigurer

All Known Implementing Classes:

AsyncConfigurerSupport

public interface AsyncConfigurer

Interface to be implemented for customizing the Executor instance used when processing async method invocations or the AsyncUncaughtExceptionHandler instance used to process exceptions thrown from async methods with a void return type.

Typically implemented by @Configuration classes annotated with @EnableAsync. See the @EnableAsync javadoc for usage examples.

NOTE: An AsyncConfigurer will get initialized early. Do not inject common dependencies into autowired fields directly; instead, consider declaring a lazy ObjectProvider for those.
