ThreadPoolTaskExecutor 创建线程池管理

 <bean id="threadPool"
  class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
  <property name="corePoolSize" value="2" />
  <property name="maxPoolSize" value="8" />
  <property name="queueCapacity" value="10" />
 </bean>

corePoolSize:默认开启线程数；maxPoolSize：最大线程数；queueCapacity：缓冲任务队列的长度；

threadPool.execute(new Runnable() {

public void run() {
//异步任务
}
 });
