spring boot+apache camel+mongodb集成问题

Question

我是新的阿帕奇骆驼，刚刚开始。我有一个spring boot(MVC)+mongodb项目已经运行良好，当我试图将其与apache camel集成时，控制台出现异常。根据我对异常的理解，spring boot试图说明，当我在项目的任何其他地方使用@componentScan(basePackages=“PackagePath”）时，我不能在骆驼路由文件上使用默认的notaion@component。因为它是一个MVC架构，我有控制器、服务和存储库，我不能忽略，请帮助我解决这个问题。

控制台异常

启动ApplicationContext时出错。若要显示条件报告，请在启用“调试”的情况下重新运行应用程序。2018-03-15 17:17:55.426错误744--[main]O.S.Boot.SpringApplication

Answer 1

问题是RelaxedPropertyResolver在spring-boot的最新版本(2.0.0.release)中被删除了。但是，最新的camel-spring-boot-starter模块（写这个时是2.20.2)仍然依赖于缺失的RelaxedPropertyResolver。

要解决这个问题，直到有新版本的Camel之前，您需要将spring-boot降级到1.5.10.release。
