#spring-actuate

On top of our first helloworld project. Let’s add some interesting spring-boot features.

           https://spring.io/guides/gs/actuator-service/

1.  Spring Boot Actuator 

This plugin can help monitoring the health status of the server status. simply include this to the dependencies part of your build.gradle file:-

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

Then, you can find a list of URL mappings from this URL:-

    http://localhost:8080/mappings

You can find a list of end points added by the actuator service. Try it one by one yourselves. They are interesting.

 "{[/metrics/{name:.*}],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.MetricsMvcEndpoint.value(java.lang.String)"  },  "{[/metrics],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"  },  "{[/autoconfig],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"  },  "{[/dump],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"  },  "{[/beans],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"  },  "{[/env/{name:.*}],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EnvironmentMvcEndpoint.value(java.lang.String)"  },  "{[/env],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"  },  "{[/mappings],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"  },  "{[/info],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"  },  "{[/configprops],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"  },  "{[/trace],methods=[GET]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"  },  "{[/health]}": {    "bean": "endpointHandlerMapping",    "method": "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.HealthMvcEndpoint.invoke(java.security.Principal)"  }

2. Change server port and actuate management port.

Add a resource file src/main/resources/application.properties with the following contents:

server.port: 9000 management.port: 9001 management.address: 127.0.0.1
