java 一个方法里面的 所有方法并行执行 用线程

package com.example.springbootycw.schedule;import java.util.Arrays;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;public class ParallelExecutionExample {public static void main(String[] args) {// 创建一个固定大小的线程池   线程是 5 那就 最多只放  5个线程ExecutorService executor = Executors.newFixedThreadPool(5);String content = "";List<String> monitorTypeList = Arrays.asList();//定义执行哪个 方法 list 集合Set<String> missingIds = new HashSet<>(monitorTypeList);for (String missingId : missingIds) {// 每天中午12点执行if (missingId.equals("A")) {executor.submit(() -> {for (int i = 0; i < 10; i++) {// 执行任务System.out.println("A定时任务: " + i);// 模拟任务耗时try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}});}// 每天早上5点执行if (missingId.equals("B")) {executor.submit(() -> {for (int i = 0; i < 10; i++) {// 执行任务System.out.println("B定时任务: " + i);// 模拟任务耗时try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}});}// 每天早上1点执行if (missingId.equals("C")) {executor.submit(() -> {for (int i = 0; i < 10; i++) {// 执行任务System.out.println("C定时任务: " + i);// 模拟任务耗时try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}});}//D	 每天早上1点执行if (missingId.equals("D")) {executor.submit(() -> {for (int i = 0; i < 10; i++) {// 执行任务System.out.println("D定时任务: " + i);// 模拟任务耗时try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}});}}// 关闭线程池executor.shutdown();}
