spring boot actuator for standalone spring application - spring

Question

I am trying to learn spring boot actuator. I have a simple basic application which runs via main method. It has not tomcat or anything. It has just one class as below
public class StartUp {
public static void main(String... args) throws InterruptedException {
ConfigurableApplicationContext ctx = SpringApplication.run(StartUp.class,
args);
StartUp mainObj = ctx.getBean(StartUp.class);
mainObj.init();
System.out.println("Application exited");
}
public void init() throws InterruptedException {
System.out.println("inside init method");
Thread.sleep(10 * 60 * 1000);
System.out.println("outside init method");
}
}
I have configured spring actuator as below in pom:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.3.RELEASE</version>
</parent>
<dependencies>
<!-- [3] -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
I was trying to view the applications health and info, i have configured the below in application.properties
management.port=8091
management.address=127.0.0.1
management.security.enabled=false
endpoints.shutdown.enabled=true
info.app.name=Startup Dashboard
info.app.version=2.0-ALPHA
logging.file=dashboard.log
while trying the url : http://localhost:8091/info
it never gets resolved.
Is it not possible to configure actuator for standalone applications ?

Answer 1

Your application is not a Spring Boot App yet.
One has to use the #SpringBootApplication at the minimum to convert an app into one.
#SpringBootApplication
public class BootadminMsAlphaApplication {
public static void main(String[] args) {
SpringApplication.run(BootadminMsAlphaApplication.class, args);
}
}
is one such simplest example.
Without this, the spring-boot dependency in your classpath have not been asked to do its magical things to make your application smart. The all-in-one annotation brings spring-boot's auto-configuration into play, that configures a lot of good stuff for the app, including Actuators (if in classpath).

Answer 2

It looks like your application isn't a Spring Boot application. It needs to be.
