利用队列的自动阻塞和线程池来做线程的生产消费

1.相关实体

package com.royalnu.psis.interfaces.psp.api.model;

import com.royalnu.core.module.com.Identifiable;
import lombok.Getter;
import lombok.Setter;

@Setter
@Getter
public class PspMsg extends Identifiable {
private static final long serialVersionUID = 1L;

    /**
     * <pre>
     * xml内容
     * </pre>
     * 
     */
    private String xmlContent;

    /**
     * <pre>
     * 服务器IP
     * </pre>
     * 
     */
    private String serverIp;

}

 2.定义队列静态属性减少在构造器中传递

package com.royalnu.psis.interfaces.psp.provider.threads;
import java.util.concurrent.BlockingQueue;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.LinkedBlockingQueue;
import com.royalnu.psis.interfaces.psp.api.model.PspMsg;

public class ThreadConstants {
 public static final ExecutorService cachedThreadPool = Executors.newCachedThreadPool(); 
 public static final BlockingQueue<PspMsg> PspMsgQueue = new LinkedBlockingQueue<PspMsg>();
}

 3.生产者

package com.royalnu.psis.interfaces.psp.provider.threads;
import java.util.List;
import javax.annotation.Resource;
import com.royalnu.psis.interfaces.psp.api.model.PspMsg;
import com.royalnu.psis.interfaces.psp.api.service.PspMsgService;
import lombok.extern.log4j.Log4j2;

@Log4j2
public class PspProduceDealThread implements Runnable {

	private List<PspMsg> pspMsgList;
	private boolean isData = true;

	public PspProduceDealThread() {

	}

	public PspProduceDealThread(List<PspMsg> pspMsgList) {
		this.pspMsgList = pspMsgList;

	}

	public void run() {

		while (isData) {
			try {

				for (PspMsg pspMsg : pspMsgList) {
					ThreadConstants.PspMsgQueue.put(pspMsg);
					log.info("生产" + pspMsg.getServerIp());
					Thread.sleep(500L);
				}

			} catch (Exception e) {
				e.printStackTrace();
			}
		}
	}
}

 4.消费者

package com.royalnu.psis.interfaces.psp.provider.threads;
import com.royalnu.psis.interfaces.psp.api.model.PspMsg;
import lombok.extern.log4j.Log4j2;

@Log4j2
public final class PspConsumerDealThread implements Runnable {

	public void run() {
		
		while (true) {
			try {
				PspMsg take = ThreadConstants.PspMsgQueue.take();
				log.info("消费" + take.getServerIp());
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
		
	}
}

 5.生产消费处理类主要方法

	List<PspMsg> pspMsgList = new LinkedList<PspMsg>();		
			for (int i = 1; i < 10; i++) {
				PspMsg pspMsg = new PspMsg();
				pspMsg.setServerIp(String.valueOf(i));
				pspMsgList.add(pspMsg);
			}
		
			
       PspProduceDealThread produceDealThread = new PspProduceDealThread(pspMsgList);
       ThreadConstants.cachedThreadPool.execute(produceDealThread);

	 PspConsumerDealThread consumerDealThread = new PspConsumerDealThread();
	 ThreadConstants.cachedThreadPool.execute(consumerDealThread);
