如何在Spring Boot中编写CompletableFuture循环(在for循环中调用)？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-async</artifactId>
</dependency>

import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service;

@Service
public class MyService {

    @Async
    public CompletableFuture<String> doSomethingAsync(int i) {
        // 异步操作的逻辑
        // 返回一个CompletableFuture对象
    }
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ExecutionException;

@RestController
public class MyController {

    @Autowired
    private MyService myService;

    @GetMapping("/async")
    public void doAsync() throws ExecutionException, InterruptedException {
        List<CompletableFuture<String>> futures = new ArrayList<>();

        for (int i = 0; i < 10; i++) {
            CompletableFuture<String> future = myService.doSomethingAsync(i);
            futures.add(future);
        }

        CompletableFuture<Void> allFutures = CompletableFuture.allOf(futures.toArray(new CompletableFuture[0]));
        allFutures.get(); // 等待所有异步操作完成
    }
}
