本文整理了Java中org.bson.conversions.Bson类的一些代码示例，展示了Bson类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Bson类的具体详情如下：
包路径：org.bson.conversions.Bson
类名称：Bson

Bson介绍

[英]An interface for types that are able to render themselves into a BsonDocument.
[中]类型的接口，这些类型能够将自己呈现到BsonDocument中。
