java - 什么取代了 MongoDB AggregationOutput 类？

Question

所有方法都已被弃用，但我无法找到用于与 java 驱动程序聚合的替代类。

Answer 1

感谢 evachooly 的回答，这是要做的。
替换:

 AggregationOutput output = collection.aggregate(pipe);
 for (DBObject obj : output.results()) {
     //...
 }

通过

  // this build of options is taken from the original method
  // aggregate(pipe) to have same behaviour
  AggregationOptions options = AggregationOptions.builder()
            .outputMode(AggregationOptions.OutputMode.INLINE)
            .build();

  Cursor cursor = collection.aggregate(pipe,options); 
  while (cursor.hasNext() ) {
      DBObject obj = cursor.next();
      //...
  }
