Answer 1

You need to enable Jolokia endpoint on your Spring Boot app and make it accessible outside of the app.
To do so, firstly you need to add spring-boot-actuator in pom.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-actuator</artifactId>
</dependency>
Then in your application.properties, disable sensitivity of the Jolokia endpoint:
endpoints.jolokia.sensitive = false
Now you should be able to connect to Jolokia at: http://localhost:8080/jolokia Try connecting to it from your hawtio console.
FYI, here you can find a working example of hawtio integration with a Spring Boot app:
