链式

 public static void main(String[] args) throws Exception {
   
    	 CompletableFuture<Integer> thenCompose = T1()
        .thenCompose(Compress::T2)
        .thenCompose(Compress::T3);

	    System.out.println(result);
    	 
    }
    // 假设这些是异步操作，并返回CompletableFuture<Integer>
    public static CompletableFuture<Integer> T1() {
   
        return CompletableFuture.supplyAsync
