Java – how do I prevent the spring boot daemon / server application from shutting down immediately?

My spring boot application is not a web server, but it is a server using a custom protocol (using camel in this case)

However, after starting, the spring start will stop immediately (elegant) How to prevent this?

I want the application to stop if Ctrl C or programming

@CompileStatic
@Configuration
class CamelConfig {

    @Bean
    CamelContextfactorybean camelContext() {
        final camelContextFactory = new CamelContextfactorybean()
        camelContextFactory.id = 'camelContext'
        camelContextFactory
    }

}

Solution

From Apache camel 2.17, there is a cleaner answer quote http://camel.apache.org/spring-boot.html ： @H_ 502_ 12@

To keep the main thread blocked so that Camel stays up,either include the spring-boot-starter-web dependency,or add camel. springboot. main-run-controller=true to your application. properties or application. yml file.

You also need the following dependencies:

Groupid gt of < dependency > < & gt; org. apache. Groupid gt of camel < / & gt< Artifactid's > camel spring guided start < / artifactid's > < version > 2.17 0 < / version > < / dependency >

Explicitly replace < version > 2.17 0 < / version > or use BOM to import dependency management information for consistency
