Java异步任务编排：如何高效处理多个依赖型第三方接口调用？

public static void main(String[] args) {
    ExecutorService executor = Executors.newFixedThreadPool(4); // 自定义线程池

    CompletableFuture<Boolean> task1 = CompletableFuture.supplyAsync(() -> {
        // 调用接口1，并返回校验结果 (true/false)
        return checkResult(callInterface1());
    }, executor);

    task1.thenAccept(result -> {
        if (result) {
            CompletableFuture<Void> task2 = CompletableFuture.runAsync(() -> callInterface2(), executor);
            CompletableFuture<Void> task3 = CompletableFuture.runAsync(() -> callInterface3(), executor);
            CompletableFuture<Void> task4 = CompletableFuture.runAsync(() -> callInterface4(), executor);

            CompletableFuture.allOf(task2, task3, task4).join(); // 等待所有任务完成
        }
    });

    executor.shutdown();
}

// 模拟接口调用和结果校验 (需替换为实际代码)
private static Object callInterface1() { /* ... */ }
private static Object callInterface2() { /* ... */ }
private static Object callInterface3() { /* ... */ }
private static Object callInterface4() { /* ... */ }
private static boolean checkResult(Object result) { /* ... */ }
