Spring boot health check on existing webapp

Question

I have existing Spring MVC web application. Now I just want to use the health check feature present in spring-boot-starter-actuator.

I am new to spring boot, so not

Answer 1

First of all I'd like tell that sidgate's answer is correct. But maybe somebody need to enable all metrics or choose different set of metrics.

You still can use spring-boot-starter-actuator instead of spring-boot-actuator

For enabling all metrics

@org.springframework.context.annotation.Configuration
@org.springframework.boot.autoconfigure.EnableAutoConfiguration
@org.springframework.boot.actuate.autoconfigure.ManagementContextConfiguration
public class MyApplicationContext {
}

where @EnableAutoConfiguration

org.springframework.boot.actuate.autoconfigure.AuditAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.CacheStatisticsAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.CrshAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.EndpointAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.EndpointMBeanExportAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.EndpointWebMvcAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.HealthIndicatorAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.InfoContributorAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.JolokiaAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.ManagementServerPropertiesAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.ManagementWebSecurityAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.MetricFilterAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.MetricRepositoryAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.MetricsDropwizardAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.MetricsChannelAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.MetricExportAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.PublicMetricsAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.TraceRepositoryAutoConfiguration,
org.springframework.boot.actuate.autoconfigure.TraceWebFilterAutoConfiguration.class

and @ManagementContextConfiguration

org.springframework.boot.actuate.autoconfigure.EndpointWebMvcManagementContextConfiguration,
org.springframework.boot.actuate.autoconfigure.EndpointWebMvcHypermediaManagementContextConfiguration

enables Spring Boot Configurations

For enabling certain management endpoints you could import endpoint's configurations directly as sidgate's already explained

@Configuration
@Import({
org.springframework.boot.actuate.autoconfigure.AuditAutoConfiguration.class,
org.springframework.boot.actuate.autoconfigure.CacheStatisticsAutoConfiguration.class,

...

})
public class MyApplicationContext {
}

P.S. Of course Spring Application Context and Properties initialization could be configured as always via annotations or xml configuration.
