问题描述

我升级了现有的Spring Boot应用程序，从springboot 1.5升级到2.0。
现在，当我尝试部署应用程序时，我收到以下错误消息。
请帮忙。

I upgraded my existing working Spring Boot application, from springboot 1.5 to 2.0. Now, I am getting below error message, when I try to deploy the application. Please help.

注意：我没有@ComponentScan，而是在我的应用程序中使用root包中的@SpringBootApplication。此外，我使用的是最新版本的apache camel springboot依赖项。

Note: I don't have @ComponentScan, instead I am using @SpringBootApplication at root package in my application. Also, I am using the latest version of apache camel springboot dependencies.

此外，如果我删除以下依赖项，应用程序部署正常，但是没有Apache Camel路由器初始化！

Also, if I remove the below dependency, the application deploys fine, but ofcourse, without Apache Camel router initialized! 

<dependency>
            <groupId>org.apache.camel</groupId>
            <artifactId>camel-spring-boot-starter</artifactId>
            <version>2.20.2</version>
</dependency>

我如何更新：更改了pom.xml中的springboot版本
使用的工具：STS （Spring Tool Suite）

How I did update: Changed the springboot version in pom.xml Tool used: STS (Spring Tool Suite)

推荐答案

解决了这个问题.Apache Camel 2.20.2是仅支持spring boot 1.5。根据Apache Camel网站，他们将从2.22（2018年夏初）开始支持春季启动。所以要解决，现在只需要使用spring boot 1.5.10。谢谢大家检查/回复。
参考链接： http://camel.apache.org/camel-2210 -release.html

Got this resolved.The Apache Camel 2.20.2 is supported for spring boot 1.5 only. As per Apache Camel website, they will extend support to spring boot starting with 2.22 (early summers 2018). So to resolve, just need to use spring boot 1.5.10 only for now. Thanks all for checking / responding. Reference Links: http://camel.apache.org/camel-2210-release.html

"This release supports only Spring Boot 1.5.x. Support for Spring Boot 2.0.x is coming in Camel version 2.22 which is planned for early summer 2018."

P.S。在 http://start.spring.io/ （切换到完整版）您可以检查Spring Project（Apache Camel）是否与Spring Boot版本兼容。目前，Initilizer显示

P.S. At http://start.spring.io/ (Switch to the full version) you can check if a Spring Project(Apache Camel) is compatible with your Spring Boot version. Currently the Initilizer shows

Apache Camel
Integration using Apache Camel
requires Spring Boot >=1.4.0.RELEASE and <2.0.0.M1
