/env上的spring配置错误

Question

我正在尝试使用spring cloud配置，1.3.0.release版本，我成功地启动了服务器

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"}}]}

我尝试用下面的pom.xml构建简单的客户端

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

                <executions>
                    <execution>

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

</project>

然后我使用mvn spring-boot：run，它总是停止

如果我添加依赖项

spring-boot-starter-web

它可以启动，但当我访问localhost:8080/env时，它总是返回404，这里缺少什么？

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";
        }

    }

如评论中所述，包括：

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