spring config error on /env

Question

I am trying with spring cloud config , for 1.3.0.release version, I started the server with success

curl localhost:8888/foo/development returns

{"name":"foo","profiles":["development"],"label":null,"version":null,"state":null,"propertySources":[{"name":"https://github.com/spring-cloud-samples/config-repo/foo-development.properties","source":{"bar":"spam","foo":"from foo development"}},{"name":"https://github.com/spring-cloud-samples/config-repo/foo.properties","source":{"democonfigclient.message":"hello spring io","foo":"from foo props"}},{"name":"https://github.com/spring-cloud-samples/config-repo/application.yml","source":{"info.description":"Spring Cloud Samples","info.url":"https://github.com/spring-cloud-samples","eureka.client.serviceUrl.defaultZone":"http://localhost:8761/eureka/","foo":"baz"}}]}

I tried build the simple client with pom.xml below

<?xml version="1.0" encoding="UTF-8"?>

                </executions>
            </plugin>
        </plugins>
    </build>

</project>

Then I use mvn spring-boot:run, it always stopped

If I add the dependency

org.springframework.boot spring-boot-starter-web

it can start, but when I visited localhost:8080/env, it always return 404, what's missing here?

Hello.java

    package hello;

    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.web.bind.annotation.RequestMapping;

    @RestController
    public class HelloController {

        @RequestMapping("/")
        public String index() {
            return "Hello World";
        }

    }

As mentioned in the comment, include:

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