1.我们希望玩家的业务在玩家线程执行无需回调因此是多线程处理。
2.匹配线程负责匹配逻辑是单独一个线程。
3.排行榜线程负责玩家的上榜等。
4.从排行榜线程获取到排行榜列表后需要给玩家发奖修改玩家数据因此涉及到排行榜线程和玩家线程的交互。
5.房间线程也希望有多个这样子各个房间之间业务无交互进行并行执行。 ThreadManager.java // 负责所有线程的创建
package org.example.testLogicAndRank;import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;public class ThreadManager {/*** 逻辑专用线程*/public static ExecutorService[] logicThreadArr;/*** 房间专用线程*/public static ExecutorService[] roomThreadArr;/*** 排行榜专用线程*/public static ExecutorService rankExecutorService Executors.newSingleThreadExecutor(r - {Thread t new Thread(r);t.setName(RankThread);return t;});/*** 匹配专用线程*/public static ExecutorService matchExecutorService Executors.newSingleThreadExecutor(r - {Thread t new Thread(r);t.setName(RankThread);return t;});public static void init() {// 逻辑线程池logicThreadArr new ExecutorService[Runtime.getRuntime().availableProcessors()];for (int i 0; i logicThreadArr.length; i) {int finalI i;logicThreadArr[i] Executors.newSingleThreadExecutor(r - {Thread t new Thread(r);t.setName(LogicThread finalI);return t;});}// 房间线程池roomThreadArr new ExecutorService[Runtime.getRuntime().availableProcessors()];for (int i 0; i roomThreadArr.length; i) {int finalI i;roomThreadArr[i] Executors.newSingleThreadExecutor(r - {Thread t new Thread(r);t.setName(RoomThread finalI);return t;});}}
}LogicThreadManager.java //逻辑线程池
package org.example.testLogicAndRank;import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ExecutorService;
import java.util.function.Consumer;public class LogicThreadManager {/*** 从其他线程执行一个任务然后将结果提交到逻辑线程** param completableFuture* param consumer* param T*/public static T void executeInLogicThread(CompletableFutureT completableFuture, ConsumerT consumer, Object hashObj) {ExecutorService executorService ThreadManager.logicThreadArr[Math.abs(hashObj.hashCode()) % ThreadManager.logicThreadArr.length];completableFuture.thenAcceptAsync(consumer, executorService);}
}RankThreadManager.java
package org.example.testLogicAndRank;import com.google.common.collect.Lists;
import lombok.extern.slf4j.Slf4j;import java.util.List;
import java.util.concurrent.Callable;
import java.util.concurrent.CompletableFuture;Slf4j
public class RankThreadManager {public static CompletableFutureListInteger getRankList() {return submitInRankThread(() - {// 查询数据库log.info(查询排行榜);return Lists.newArrayList(1, 2, 3, 4, 5);});}/*** 在排行榜线程执行某个操作,有返回值** param callable* param T* return*/public static T CompletableFutureT submitInRankThread(CallableT callable) {return CompletableFuture.supplyAsync(() - {try {return callable.call();} catch (Exception e) {log.error(, e);}return null;}, ThreadManager.rankExecutorService);}/*** 在排行榜线程执行某个操作,无返回值*/public static void executeInRankThread(Runnable runnable) {ThreadManager.rankExecutorService.submit(runnable);}
}Main.java
package org.example.testLogicAndRank;import lombok.extern.slf4j.Slf4j;import java.util.List;
import java.util.concurrent.CompletableFuture;Slf4j
public class Main {public static void main(String[] args) {ThreadManager.init();// 排行榜CompletableFutureListInteger rankListFuture RankThreadManager.getRankList();// 假设是给玩家1和2发奖LogicThreadManager.executeInLogicThread(rankListFuture, (rankList) - {log.info(拿到排行榜数据发奖{}, rankList);}, 1);LogicThreadManager.executeInLogicThread(rankListFuture, (rankList) - {log.info(拿到排行榜数据发奖{}, rankList);}, 2);}
}/*
17:16:39.314 [RankThread] INFO org.example.testLogicAndRank.RankManager - 查询排行榜
17:16:39.343 [LogicThread2] INFO org.example.testLogicAndRank.Main - 拿到排行榜数据发奖[1, 2, 3, 4, 5]
17:16:39.343 [LogicThread1] INFO org.example.testLogicAndRank.Main - 拿到排行榜数据发奖[1, 2, 3, 4, 5]*/总结
可以看出来我们不再需要什么Promise模式了有了CompletableFuture后业务线程的编排和交换数据变得非常容易了
