相同的 pom.xml 在 6.1.0 上运行良好，只是在移动到 7.0.0M2 时我将 camel.version 从 2.16.1 更改为 2.16.3 ] 和 jackson.version 和 jackson.afterburner.version 从 2.6.2 到 2.7.5。
谁能告诉我出了什么问题？从 6.1.0 转到 7.0.0M2 时，我还需要更改其他任何内容吗？
修改我的 pom.xml 和 feature.xml 以使用 camel-jetty9 解决了这个问题。
我在 pom.xml
中进行了以下更改
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-jetty9</artifactId>
<version>${camel.version}</version>
<scope>provided</scope>
</dependency>
feature.xml 中也有以下变化：-
<feature version="${camel.version}">camel-jetty9</feature>
其中 <camel.version>2.16.3</camel.version>
骆驼版本是 2.16.3 我也不得不卸载骆驼码头。只有 camel-jetty9 似乎有效。
feature:uninstall camel-jetty/2.16.3
