需求：玩家會隨機加入遊戲，當第一個玩家加入匹配後最多等待時間T，每局遊戲固定人數N git代碼庫：https://gitee.com/ichiva/game_matching.gitjava
匹配接口
package com.company;
import java.util.Collection;
import java.util.Set;
/**
* 通用匹配
*
* @param <T>
*/
public interface Match<T> {
/**
* 添加匹配
* @param ele
*/
void add(T ele);
/**
* 匹配成功
* @param list
*/
void success(Collection<T> list);
/**
* 匹配失敗，未達到固定匹配人數
* @param list
*/
void fail(Collection<T> list);
}
超時匹配實現
package com.company;
import java.util.HashSet;
import java.util.LinkedHashSet;
import java.util.Set;
import java.util.concurrent.*;
/**
* 超時匹配
* @param <T>
*/
public abstract class TimeoutMatch<T> extends Thread implements Match<T> {
/**
* 匹配超時時間
*/
private final long timeout;
private final int capacity;
private final ExecutorService executorService;
private final LinkedBlockingDeque<T> deque = new LinkedBlockingDeque<>();
public TimeoutMatch(int capacity, long timeout){
this(capacity,timeout,Executors.newSingleThreadExecutor());
}
public TimeoutMatch(int capacity, long timeout,ExecutorService executorService){
this.capacity = capacity;
this.timeout = timeout;
this.executorService = executorService;
start();
}
@Override
public void add(T ele){
deque.push(ele);
}
@Override
public void run() {
while (!Thread.currentThread().isInterrupted()){
try {
T start = deque.take();
System.out.println("匹配開始");
Future<Set<T>> submit = executorService.submit(new Task(start));
try {
Set<T> list = submit.get(timeout, TimeUnit.SECONDS);
success(list);
}catch (TimeoutException e) {
submit.cancel(true);
}catch (Exception e){
e.printStackTrace();
}
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
}
}
}
private class Task implements Callable<Set<T>>{
private final T start;
public Task(T start){
this.start = start;
}
@Override
public Set<T> call() {
Set<T> list = new LinkedHashSet<>(capacity);
list.add(start);
System.out.println("放入臨時匹配隊列" + start);
try {
while (list.size() != capacity){
T ele = deque.take();
list.add(ele);
System.out.println("放入臨時匹配隊列" + ele);
}
}catch (InterruptedException e) {
fail(list);
}
return list;
}
}
}
測試用例
package com.company.test;
import com.company.TimeoutMatch;
import java.util.Collection;
import java.util.UUID;
public class TimeoutMatchTests {
public static void main(String[] args) throws InterruptedException {
TestTimeoutMatch match = new TestTimeoutMatch(3,3);
while (true){
int num = (int) (Math.random() * 3);
System.out.printf("加入【%d】人\r\n", num);
for (int i = 0; i < num; i++) {
match.add(UUID.randomUUID().toString());
}
Thread.sleep(1500);
}
}
static class TestTimeoutMatch extends TimeoutMatch<String> {
public TestTimeoutMatch(int capacity, long timeout) {
super(capacity, timeout);
}
@Override
public void success(Collection<String> list) {
System.out.println("匹配成功");
for (String item : list) {
System.out.println("\t" + item);
}
}
@Override
public void fail(Collection<String> list) {
System.err.println("匹配失敗");
for (String item : list) {
System.err.println("\t" + item);
}
}
}
}
