executor.xml的配置如下：

测试类ExecutorTest1.java的代码：

package com.soecode.lyf.web.test;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

public class ExecutorTest1 {


	@Test
	public void test() {

		try {

			ApplicationContext context1  = new ClassPathXmlApplicationContext("executor.xml"); 
			ThreadPoolTaskExecutor taskExecutor = (ThreadPoolTaskExecutor)context1.getBean("taskExecutor");
			for(int i=0;i<10;i++){
				taskExecutor.execute(new Runnable(){
					@Override
					public void run() {
						System.out.println(Thread.currentThread());
					}
				});
			}
			System.out.println("main方法结束");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}
