Spring线程池开发实战 - JAVA

本文提供了三个Spring多线程开发的例子，由浅入深，由于例子一目了然，所以并未做过多的解释。诸位一看便知。

前提条件：
1）在Eclipse创建一个Java项目，我取名为SpringThreadDemo。
2）项目所需的JAR包如图所示：

下面开始。

注：项目源码已经托管到GitHub，

例子1：Spring结合Java线程。
通过继承Thread创建一个简单的Java线程，然后使用@Component让Spring容器管理此线程，Bean的范围必须是prototype，因此每个请求都会返回一个新实例，运行每个单独的线程。
PrintThread.java
[java]
package com.chszs.thread;

import org.springframework.stereotype.Component;
import org.springframework.context.annotation.Scope;

@Component
@Scope("prototype")
public class PrintThread extends Thread{
@Override
public void run(){
System.out.println(getName() + " is running.");
try{
Thread.sleep(5000);
}catch(InterruptedException e){
e.printStackTrace();
}
System.out.println(getName() + " is running again.");
}
}

AppConfig.java
[java]
package com.chszs.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan(basePackages="com.chszs.thread")
public class AppConfig {
}
App.java
[java]
package com.chszs;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

import com.chszs.config.AppConfig;
import com.chszs.thread.PrintThread;

public class App {
public static void main(String[] args){
ApplicationContext ctx =
new AnnotationConfigApplicationContext(AppConfig.class);
PrintThread printThread1 = (PrintThread)ctx.getBean("printThread");
printThread1.setName("Thread 1");

PrintThread printThread2 = (PrintThread)ctx.getBean("printThread");
printThread2.setName("Thread 2");

PrintThread printThread3 = (PrintThread)ctx.getBean("printThread");
printThread3.setName("Thread 3");

PrintThread printThread4 = (PrintThread)ctx.getBean("printThread");
printThread4.setName("Thread 4");

PrintThread printThread5 = (PrintThread)ctx.getBean("printThread");
printThread5.setName("Thread 5");

printThread1.start();
printThread2.start();
printThread3.start();
printThread4.start();
printThread5.start();
}
}

输出：
Thread 1 is running.
Thread 2 is running.
Thread 4 is running.
Thread 5 is running.
Thread 3 is running.
Thread 2 is running again.
Thread 1 is running again.
Thread 5 is running again.
Thread 4 is running again.
Thread 3 is running again.

例子2：Spring线程池结合非Spring托管Bean。
使用Spring的ThreadPoolTaskExecutor类创建一个线程池。执行线程无需受Spring容器的管理。

PrintTask.java
[java]
package com.chszs.thread;

public class PrintTask implements Runnable{
String name;
public PrintTask(String name){
this.name = name;
}
@Override
public void run() {
System.out.println(name + " is running.");
try{
