org.springframework.scheduling.concurrent .ConcurrentTaskExecutor

ConcurrentTaskExecutor

public class ConcurrentTaskExecutor implements SchedulingTaskExecutor,Executor(Code)

Adapter that takes a JDK 1.5 java.util.concurrent.Executor and exposes a Spring org.springframework.core.task.TaskExecutor for it.

NOTE: This class implements Spring's org.springframework.core.task.TaskExecutor interface as well as the JDK 1.5 java.util.concurrent.Executor interface, with the former being the primary interface, the other just serving as secondary convenience. For this reason, the exception handling follows the TaskExecutor contract rather than the Executor contract, in particular regarding the org.springframework.core.task.TaskRejectedException .

Note that there is a pre-built ThreadPoolTaskExecutor that allows for defining a JDK 1.5 java.util.concurrent.ThreadPoolExecutor in bean style, exposing it as a Spring org.springframework.core.task.TaskExecutor directly. This is a convenient alternative to a raw ThreadPoolExecutor definition with a separate definition of the present adapter class.
