About Spring encapsulation Java thread pool Understanding __ Thread pool

The project is Taskexecutor, and I think some of it is configured through the Spring bean. Some of them were configured in a way that looked at the official document, and the official document (as if it were chapter 30.5) was clearly written on the meaning of the parameters inside,

<bean id= "Taskexecutor" class= "Org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor" >
	< !--Core Thread Count-->	 
	<property name= "corepoolsize" value= "${task.core_pool_size}"/>
	<!--max Threads-->  
	<property name= "maxpoolsize" value= "${task.max_pool_size}"/>
	<!--queue Maximum length-->
	Name= "queuecapacity" value= "${task.queue_capacity}"/>
	<!--thread pool to maintain the idle time allowed by the thread, by default 60s-->
	< Property Name= "Keepaliveseconds" value= "${task.keep_alive_seconds}"/>
</bean>
<!--callout type-->
<task:annotation-driven/>
<!--or-->
   <task:executor id= "Asynctaskexecutor"
                   Pool-size= "${executor.pool.size}"
                   queue-capacity= "${executor.queue.capacity}"
                   keep-alive= "/>"

As for the configuration/use of the SPRINGMVC consolidated Taskexecutor thread pool
First, configure Jdbc.properties add:

#------------Task------------
task.core_pool_size=5
task.max_pool_size=50
task.queue_capacity=1000
task.keep_alive_seconds=60

Second, configure Spring's applicationcontext.xml add:
is the configuration above.

Declaration and injection of IMPL in the implementation layer:

       

@Resource (name = "Taskexecutor")
    private taskexecutor taskexecutor;

Four, in the method calls:

	try {
			Taskexecutor.execute (new Runnable () {public
				void run () {
					//write Processing business code
					
				}
			}});
		catch (Exception e) {
			e.printstacktrace ();
		}
