Implement Spring Actuator in my Spring MVC app wit

问题:

Currently I have a legacy project that uses spring MVC. Now there is need to implement Spring boot actuator. So my questions are

1. Can I implement Spring Actuator in my Spring MVC app without adding Spring boot
2. Can I have both Spring boot and spring MVC in one single application. If Yes then how.

It would be great if someone can describe step by step implementation of it. I am using Eclipse, Gradle, Tomcat

To answer your first question:

1. yes You can use actuator in your spring mvc project. Add this to pom.xml

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-actuator</artifactId>
       <version>Compatible version with mvc</version>
   </dependency>
   

2. Add configuration below

   @Configuration
   @EnableWebMvc
   @Import({EndpointAutoConfiguration.class , PublicMetricsAutoConfiguration.class , HealthIndicatorAutoConfiguration.class
   })
   public class MyActuatorConfig {
   
       @Bean
       @Autowired
       public EndpointHandlerMapping endpointHandlerMapping(Collection<? extends MvcEndpoint> endpoints) {
         return new EndpointHandlerMapping(endpoints);
       }
   
      @Bean
      @Autowired
      public EndpointMvcAdapter metricsEndPoint(MetricsEndpoint delegate) {
         return new EndpointMvcAdapter(delegate);
     }
   }
   

2. Answer your second questions

Of course you can use Spring boot and spring MVC, just simple have below as parent to manage all dependencies version etc..

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

and spring-boot-starter-web as dependency.

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