org.apache.camel.NoTypeConversionAvailableException：没有可用的类型转换器

Question

我将一个java应用程序从Camel 2.13.4升级到2.17.3＆amp;我得到下面列出的例外。该应用程序在升级之前工作正常。我现在需要在Camel路线中增加一个额外的条目吗？下面列出的是代码＆amp;路由配置，我认为是相关的。

异常

Caused by: org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: com.application.header.TestFileHeader to the required type: java.util.ArrayList with value com.application.header.TestFileHeader@1aac3b2c
