不廢話上代碼。
package com.huyi.csdn.tools; import cn.hutool.core.thread.ThreadUtil; import com.google.common.util.concurrent.Monitor; import org.springframework.scheduling.concurrent.CustomizableThreadFactory; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import java.util.function.Function; /** * @Program: csdn @ClassName: MonitorRunner @Author: huyi @Date: 2021-10-30 15:22 @Description: * 監(jiān)視器Runner @Version: V1.0 */ public class MonitorRunner<T> implements Runnable { private T param; private Function<T, Boolean> condition; private Runnable runnable; private Monitor monitor; /** * 構(gòu)造函數(shù) * * @param param 判斷參數(shù) * @param condition 判定函數(shù) * @param runnable 執(zhí)行內(nèi)容 */ public MonitorRunner(T param, Function<T, Boolean> condition, Runnable runnable) { this.param = param; this.condition = condition; this.runnable = runnable; monitor = new Monitor(); } @Override public void run() { System.out.println("線程開始"); Monitor.Guard guard = new Monitor.Guard(monitor) { @Override public boolean isSatisfied() { return condition.apply(param); } }; while (true) { if (monitor.enterIf(guard)) { try { runnable.run(); } finally { monitor.leave(); break; } } else { continue; } } } public T getParam() { return param; } public MonitorRunner<T> setParam(T param) { this.param = param; return this; } public static void main(String[] args) { ExecutorService executorService = Executors.newFixedThreadPool(10, new CustomizableThreadFactory("MONITOR-")); MonitorRunner<Integer> monitorRunner = new MonitorRunner<>( 0, x -> x > 10, () -> { // todo 線程需要執(zhí)行的內(nèi)容 System.out.println("今天天氣真好"); }); executorService.submit(monitorRunner); while (monitorRunner.getParam() <= 10) { monitorRunner.setParam(monitorRunner.getParam() + 1); ThreadUtil.sleep(1000L); System.out.println("當(dāng)前Param的值:" + monitorRunner.getParam()); } ThreadUtil.sleep(5000L); executorService.shutdown(); } }
代碼說明
主要在構(gòu)造對象的時候需要傳遞泛型的校驗(yàn)對象,以及斷言和需要執(zhí)行的Runable。
執(zhí)行結(jié)果
