Connection Refused Error in Cloud Foundry Spring Boot application

Question

I have been facing issue with deploying a spring boot application in Pivotal Cloud Web Foundry. I keep getting this error:

 2018-01-29T22:18:50.84-0500 [HEALTH/0] ERR Failed to make HTTP request to '/' on port 8080: connection refused
 2018-01-29T22:18:50.84-0500 [CELL/0] ERR Timed out after 15s: health check never passed.

Controller class

    return new ResponseEntity("Hello world", HttpStatus.ACCEPTED);

Application

@SpringBootApplication
public class TransferFundApplication extends SpringBootServletInitializer {

public static void main(String[] args) {
    SpringApplication.run(TransferFundApplication.class, args);
}

/**

 */
@Override

    return builder.sources(TransferFundApplication.class);

}

manifest.yml

applications:
- name: target
  path: target/TransferFund-0.0.1-SNAPSHOT.jar
  health-check-type: http
  buildpack: https://github.com/cloudfoundry/java-buildpack.git

It looks like the port 8080 is not detected for some reasons. I have tried changing the health-check-type to process and port. When I change it to process it works but the endpoints are not longer accessible. Need some help in solving the issue

Answer 1

Please try after adding the following dependency of actuator :

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

Also add the following to the manifest.yml :

health-check-http-endpoint: /info
health-check-type: http

I think this should solve the problem.
