多線程實現生產者消費者模型

首先是一個倉庫接口，該接口規定的倉庫大小，倉庫的存取方法，以下所示

 1 package pers.lan.jc.pc;
 2 
 3 /**
 4  * @author lan  [1728209643@qq.com]
 5  * @create 2018-11-27 15:59
 6  * @desc 倉庫
 7  */
 8 public interface Repertory<T> {
 9 
10     int size = 10;
11 
12     void push(T t);
13 
14     T pop();
15 }

而後就是具體的倉庫設計，我利用設計了兩種不一樣實現方式的倉庫，以下

第一種：

 1 package pers.lan.jc.pc;
 2 
 3 import lombok.extern.slf4j.Slf4j;
 4 
 5 import java.util.concurrent.ConcurrentLinkedQueue;
 6 
 7 /**
 8  * @author lan  [1728209643@qq.com]
 9  * @create 2018-11-27 16:43
10  * @desc 經過syn, wait, notify實現倉庫
11  */
12 @Slf4j
13 public class SynRepertory implements Repertory<Character> {
14 
15     private final ConcurrentLinkedQueue<Character> queue = new ConcurrentLinkedQueue<>();
16 
17     @Override
18     public void push(Character character) {
19         synchronized (queue) {
20             if (queue.size() >= size) {
21                 try {
22                     log.info("滿了等待");
23                     queue.wait();
24                 } catch (InterruptedException e) {
25                     e.printStackTrace();
26                 }
27             }
28             log.info("push: " + character);
29             queue.add(character);
30             queue.notify();
31         }
32     }
33 
34     @Override
35     public Character pop() {
36         synchronized (queue) {
37             if (queue.isEmpty()) {
38                 try {
39                     log.info("空，等待");
40                     queue.wait();
41                 } catch (InterruptedException e) {
42                     e.printStackTrace();
43                 }
44             }
45             Character character = queue.poll();
46             log.info("pop: " + character);
47 
48             queue.notify();
49             return character;
50         }
51     }
52 }

第二種：

 1 package pers.lan.jc.pc;

13         Repertory repertory = new LockRepertory();
14 //        Repertory repertory = new SynRepertory();
15         Producer producer = new Producer(repertory);
16         Consumer consumer = new Consumer(repertory);

21             e.printStackTrace();
22         }
23         new Thread(consumer).start();
24     }
25 }
26 
27 @Slf4j

29 class Producer implements Runnable {
30 
31     private Repertory repertory;
32

35     }
36

52 }
53 
54 @Slf4j
55 class Consumer implements Runnable {

58 
59     Consumer(Repertory repertory) {
60         this.repertory = repertory;
61     }
62 
63     @Override
64     public void run() {
65         while (true) {
66             repertory.pop();
67             try {

72         }

74 }

測試代碼主要是定義了生產者和消費者自己的行爲規則
