Apache Camel 3.20.3升级至4.4.2引发循环依赖问题

我们正在对Java、Camel和Spring Boot进行版本升级，具体版本变更如下：

• Java：11 → 17
• Spring Boot：2.5.2 → 3.2.6
• Apache Camel：3.20.3 → 4.4.2

仅升级JDK到17时，JUnit测试用例运行正常；但同时升级Spring Boot和Apache Camel后，运行测试用例出现异常。尚未尝试部署到服务器，已执行过mvn clean install操作。

已尝试的解决方案 #

• 创建同版本的示例项目，测试用例运行正常。
• 添加Camel文档中相关健康检查配置并设置为false。
• 创建自定义类继承DefaultHealthCheckRegistry并启用懒加载。
• 在自动配置注解中排除DefaultHealthCheckRegistry类。
