我正在使用Mongo Java異步驅動程序v3.2使用以下測試。我可以看到調用了回調（在Mongo集合中使用insertOne調用註冊的回調）。我可以看到測試客戶端能夠連接到mongos進程（最後附有日誌）。我在Mongo中沒有看到任何文件。我啓用了用於分片的數據庫集合，並且我也可以從mongos進程運行分片狀態命令。有關我在設置中可能配置錯誤的任何想法？將文件插入mongo分片
CountDownLatch latch = new CountDownLatch(1);
SingleResultCallback<Void> callbackWhenFinished = new SingleResultCallback<Void>() {
@Override
public void onResult(final Void result, final Throwable t) {
System.out.println("Operation Finished!");
latch.countDown();
}
};
final Document doc = new Document("name", "MongoDB")
.append("type", "database")
.append("count", 1)
.append("info", new Document("x", 203).append("y", 102));
collection.insertOne(doc, callbackWhenFinished);
latch.await();
