描述的问题与不同Maven依赖项之间的冲突有关。在尝试使用最新版本的Spring Boot与Apache Camel时，我遇到了相同的问题。
在分析依赖树之后，发现spring-webmvc的版本为5.2.9，而所有其他spring依赖项的版本为5.2.8。
在我的情况下，我通过使用更新的camel-spring-boot-dependencies版本（3.6.0，而不是之前使用的3.5.0）来解决了这个问题。
英文:
The problem described is related to conflicts between different Maven dependencies. I've had the same problem while trying to use the latest version of Spring Boot with Apache Camel.
After analyzing the dependency tree, it turned out that the version of spring-webmvc was 5.2.9, while all other spring dependencies were of version 5.2.8.
In my case, I have solved the problem by using a newer version of camel-spring-boot-dependencies (3.6.0, unlike previously used 3.5.0).

已找到解决方案。
在我的 pom.xml 文件中有两个依赖项，如下所示：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>5.2.8.RELEASE</version>
</dependency>
我所做的是移除了 spring-web 依赖，然后重新加载所有的 Maven 插件，尝试再次运行项目。
这次运行成功了。
英文:
Found the solution.
In my pom.xml there were two dependencies like
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>5.2.8.RELEASE</version>
</dependency>
What I did was removed the spring-web dependency and reloaded all Maven Plugins and tried running the project again.
It was successful.
