可以使用Java的CompletableFuture来异步调用该方法6次,并为每次调用传入不同的imageType值。示例代码如下:
```
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ExecutionException;
import java.util.HashMap;
import java.util.Map;
public class AsyncUploadImageExample {
public static void main(String[] args) {
String[] imageTypes = {"jpg", "png", "gif", "bmp", "svg", "webp"};
CompletableFuture<Void>[] futures = new CompletableFuture[imageTypes.length];
for (int i = 0; i < imageTypes.length; i++) {
String imageType = imageTypes[i];
CompletableFuture<Void> future = CompletableFuture.runAsync(() -> {
try {
ResultsBean<Map<String, Object>> result = uploadImage(imageType);
System.out.println("Upload result for " + imageType + ": " + result.toString());
} catch (Exception e) {
System.out.println("Error uploading image for " + imageType + ": " + e.getMessage());
}
});
futures[i] = future;
}
// Wait for all futures to complete
try {
CompletableFuture.allOf(futures).get();
} catch (InterruptedException | ExecutionException e) {
System.out.println("Error waiting for all futures to complete: " + e.getMessage());
}
}
public static ResultsBean<Map<String, Object>> uploadImage(String imageType) throws Exception {
// TODO: Implement uploadImage method
return null;
}
}
```
在这个示例中,我们首先定义一个包含不同imageType值的数组。然后,我们使用for循环遍历数组并异步调用uploadImage方法。调用时,我们为每个调用传入一个不同的imageType值,并在调用完成后打印结果或错误消息。最后,我们使用CompletableFuture.allOf方法等待所有调用完成。
