I am using camel-spring-boot-starter version 3.22.1. The spring-boot application is started but the CamelContext is null and its causing the issue for the "configure()" method. Below are my code samples, any suggestion would be really helpful. What's I'm missing.

Reset to default 0Try removing all dependency and keep only the below dependency.
<dependency>
<groupId>.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>.apache.camel.springboot</groupId>
<artifactId>camel-spring-boot-starter</artifactId>
<version>4.4.0</version>
</dependency>
Keep the camel running by adding below configuration file
@Component
public class CamelKeepAlive implements ApplicationRunner {
private final CamelSpringBootApplicationController controller;
public CamelKeepAlive(CamelSpringBootApplicationController controller) {
this.controller = controller;
}
@Override
public void run(ApplicationArguments args) throws Exception {
controller.run();
}
}
Do not create camelContext bean manually now and also no need to add componentScan. Just the above two changes.
