谢谢你的帮助 您遇到的部署错误是因为类路径上没有正确版本的com.fasterxml.jackson.databindjar（如下面的所定义）。您是否正在使用功能文件进行部署？如果是，请将其包括在您的问题中 org.osgi.framework.BundleException:捆绑包中未解析的约束 aaa.bbb.ccc.camelRest[585]：无法解析585.0:缺少 要求[585.0]osgi.wiring.package； （&（osgi.willing.package=com.fasterxml.jackson.databind）（版本>=2.7.0）（！（版本>=3.0.0））
使用Processor反序列化为JSON的方法是正确的，但是我建议在Process（）方法之外创建ObjectMapper（），因为您不需要每次都创建一个新的ObjectMapper，而且创建一个ObjectMapper的成本很高 谢谢java-301！有道理我会在这个周末试一试，然后给你一个状态！不使用“功能文件”进行部署。已安装“camel jackson”（即“camel-2.17.0.redhat-630187”）。注意：我已经为IBM MQ 8.x添加了OSGI捆绑包（到部署文件夹）。这些捆绑包可能会导致某种冲突吗？多亏了你的建议，最终解决了这个问题-thx。必须查找redhat版本的camel jackson在使用什么…在此页（）上找到它。然后将pom.xml依赖项更改为相同的：“com.fasterxml.jackson.core jackson databind 2.6.3”感谢后续saim，很高兴能提供帮助。有时，这些OSGI错误可能是模糊的。
