Java 为什么Camel MongoDB组件会在writeResultAsHeader=true的情况下更改主体

我正在使用Camel 2.10.4将文档保存到Mongo 2.10.1。作为Mongo端点配置的一部分，我指定 writeResultAsHeader=true })

日志输出

我已经查看了Camel源代码，我认为可能存在一个bug（最后一行），我们在更新主体时没有检查writeResultAsHeader标志

// we always return the WriteResult, because whether the getLastError was called or not, the user will have the means to call it or 
// obtain the cached CommandResult
processAndTransferWriteResult(result, exchange);
resultMessage.setBody(result);

我看到了另一个问题，但问题略有不同

有人遇到过同样的问题吗？或者我的用法不正确？

选项WriteResultAsHeader中的WriteResult是Mongo在写入操作时返回的com.mongodb.WriteResult。它不是指写入操作结果（如find）。你可以在mongo呼叫前保存尸体，然后我想恢复是post

// we always return the WriteResult, because whether the getLastError was called or not, the user will have the means to call it or 
// obtain the cached CommandResult
processAndTransferWriteResult(result, exchange);
resultMessage.setBody(result);
