How to integrate spring actuator in a non spring boot application? - spring-boot

Question

i have a GWT application which is not a spring boot application and i managed to integrate actuator v1.5.9 with spring v4.3.3 with this configuration class.
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.actuate.autoconfigure.EndpointAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.EndpointWebMvcManagementContextConfiguration;
import org.springframework.boot.actuate.autoconfigure.HealthIndicatorAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.ManagementServerPropertiesAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.ManagementWebSecurityAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.MetricExportAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.MetricFilterAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.MetricRepositoryAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.MetricsChannelAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.MetricsDropwizardAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.PublicMetricsAutoConfiguration;
import org.springframework.boot.actuate.endpoint.EndpointProperties;
import org.springframework.boot.actuate.endpoint.HealthEndpoint;
import org.springframework.boot.actuate.endpoint.mvc.HealthMvcEndpoint;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.context.annotation.PropertySource;
#Configuration
#Import({ EndpointWebMvcManagementContextConfiguration.class, ManagementServerPropertiesAutoConfiguration.class,
EndpointAutoConfiguration.class, HealthIndicatorAutoConfiguration.class, MetricExportAutoConfiguration.class,
MetricFilterAutoConfiguration.class, MetricsChannelAutoConfiguration.class,
MetricsDropwizardAutoConfiguration.class, MetricRepositoryAutoConfiguration.class,
PublicMetricsAutoConfiguration.class,EndpointProperties.class, ManagementWebSecurityAutoConfiguration.class })
#PropertySource("classpath:Application.properties")
public class HealthCheckConfiguration {
#Bean
#Autowired
public HealthMvcEndpoint healthMvcEndpoint(HealthEndpoint delegate) {
return new HealthMvcEndpoint(delegate, true);
}
}
Could you help me to do the same in spring actuator v2.3.1 and spring v5.2.7, because there are many classes not available in the new version.
Thanks,

This configuration worked for me (for a SpringMVC project with spring boot actuator)
#Configuration
#Import({
EndpointAutoConfiguration.class,
HealthIndicatorAutoConfiguration.class,
InfoEndpointAutoConfiguration.class,
HealthEndpointAutoConfiguration.class,
WebEndpointAutoConfiguration.class,
ServletManagementContextAutoConfiguration.class,
ManagementContextAutoConfiguration.class,
})
#EnableConfigurationProperties(CorsEndpointProperties.class)
class ActuatorConfiguration {
#Bean //taken from WebMvcEndpointManagementContextConfiguration.class
public WebMvcEndpointHandlerMapping webEndpointServletHandlerMapping(WebEndpointsSupplier webEndpointsSupplier,
ServletEndpointsSupplier servletEndpointsSupplier, ControllerEndpointsSupplier controllerEndpointsSupplier,
EndpointMediaTypes endpointMediaTypes, CorsEndpointProperties corsProperties,
WebEndpointProperties webEndpointProperties) {
List<ExposableEndpoint<?>> allEndpoints = new ArrayList<>();
Collection<ExposableWebEndpoint> webEndpoints = webEndpointsSupplier.getEndpoints();
allEndpoints.addAll(webEndpoints);
allEndpoints.addAll(servletEndpointsSupplier.getEndpoints());
allEndpoints.addAll(controllerEndpointsSupplier.getEndpoints());
EndpointMapping endpointMapping = new EndpointMapping(webEndpointProperties.getBasePath());
return new WebMvcEndpointHandlerMapping(endpointMapping, webEndpoints, endpointMediaTypes,
corsProperties.toCorsConfiguration(),
new EndpointLinksResolver(allEndpoints, webEndpointProperties.getBasePath()));
}
#Bean
DispatcherServletPath dispatcherServletPath() {
return () -> "/";
}
}
I did include
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-actuator-autoconfigure</artifactId>
<version>2.1.18.RELEASE</version>
</dependency>
for compatibility with the baseline Spring version I've been using (5.1.19.RELEASE)
The actuator endpoints are exposed with /actuator/*
