Spring ThreadPoolTaskExecutor only running one thread

Question

We are using ThreadPoolExecutor in our JMS consumer and injecting it into a DefaultMessageListenerContainer. I expect this to be running concurrent threads for many messages

Answer 1

try this:

• This will create 10 threads at the time of initialization.
• If all 10 threads are busy and new task comes up, then It will keep tasks in queue.
• If queue is full it will create 11th thread and will go till 25.
• Then will throw TaskRejected Exception.
