To enable Spring Boot Actuator in your application, you will have to add Spring Boot Actuator dependency in your package manager. This is the simplest way to enable the production-ready features in your Spring application, by adding a Starter dependency, spring-boot-starter-actuator.

Let's add the Actuator to a Maven-based project as follows in your Spring Boot project:

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

The preceding Maven script will enable the production-ready features that are Spring Boot's Actuator. Now let's see how to enable the Actuator with a Gradle-based project.

Let's use the following declaration:

dependencies {
   compile("org.springframework.boot:spring-boot-starter-actuator")
} 

The preceding "Gradle script will enable the production-ready features in your Spring application.

After enabling the production-ready features, let's see what all the endpoints are that Spring Boot's Actuator provides.
