Model 如何使用多个BindyFixedLengthDataFormat模型（camel-bindy-2.16）封送数据

我目前正试图从camel-bindy-2.12.1升级到camel-bindy-2.16.2，并且在尝试将由多个类组成的模型应用于一个数据集时遇到了一个问题，导致了一个文本文件

我在一个包（com.sample.package）中有许多类，可以使用以下代码（Camel-Spring DSL）进行封送处理：

然后在封送处理时引用bean：

<marshal ref="bindyFixedLengthDataformat" />

这个bean调用将把包中的所有类应用于被封送的数据，从而生成一个文件

它在camel-bindy-2.12.1中工作得非常好，但是上面的构造函数在camel-bindy-2.16.2中不再可用

我一直无法找到任何例子，将实现相同的功能与删除的构造函数

有人遇到过这种情况吗？如果是这样，我们将非常感谢您的任何建议/示例

---

谢谢

这是一篇老文章，但我确实想出了一个解决办法。其思想是，您必须为每个类创建一个单独的bindy格式化程序……然后将每个格式化程序应用于消息体：
