Spring Cloud Kubernetes - 启用配置重新加载后，Spring启动无法启动

我有这个演示项目，它打印一个从配置中读取的标签。

这是我的主要课程：

@SpringBootApplication
@EnableDiscoveryClient
@RestController
public class DemoApplication {

private MyConfig config;
private DiscoveryClient discoveryClient;

@Autowired
public DemoApplication(MyConfig config, DiscoveryClient discoveryClient) {
    this.config = config;
    this.discoveryClient = discoveryClient;
}

@RequestMapping("/")
public String info() {
    return config.getMessage();
}

public static void main(String[] args) {
    SpringApplication.run(DemoApplication.class, args);
}

@RequestMapping("/services")
public String services() {
    StringBuilder b = new StringBuilder();
    discoveryClient.getServices().forEach((s) -> b.append(s).append(" , "));
    return b.toString();
}

}
而MyConfig类是：

@Configuration
@ConfigurationProperties(prefix = "bean")
public class MyConfig {

private String message = "a message that can be changed live";

public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
}

}
将bootstrap.properties包含以下内容：

spring.application.name=demo
spring.cloud.kubernetes.config.name=demo
spring.cloud.kubernetes.config.enabled=true
spring.cloud.kubernetes.config.namespace=default
spring.cloud.kubernetes.reload.enabled=true
spring.cloud.kubernetes.reload.monitoring-config-maps=true
spring.cloud.kubernetes.reload.strategy=refresh
spring.cloud.kubernetes.reload.mode=event
management.endpoint.refresh.enabled=true
management.endpoints.web.exposure.include=*
以及依赖关系build.gradle：

dependencies {

compile("org.springframework.boot:spring-boot-starter-web")
compile("org.springframework.boot:spring-boot-starter-actuator")
compile("org.springframework.cloud:spring-cloud-starter-kubernetes:+")
compile("org.springframework.cloud:spring-cloud-starter-kubernetes-config:+")
testCompile('org.springframework.boot:spring-boot-starter-test')
runtime("org.springframework.boot:spring-boot-properties-migrator")

}
我正在创建ConfigMap kubectl create -f configmap-demo.yml作为内容：

apiVersion: v1
kind: ConfigMap
metadata:
name: demo
data:

bean.message: This is an info from k8

在Kubernetes中部署时，我在Spring Boot启动时收到以下错误：

APPLICATION FAILED TO START

Description:

Parameter 2 of method configurationUpdateStrategy in org.springframework.cloud.kubernetes.config.reload.ConfigReloadAutoConfiguration$ConfigReloadAutoConfigurationBeans required a bean of type 'org.springframework.cloud.context.restart.RestartEndpoint' that could not be found.

The following candidates were found but could not be injected:

    - Bean method 'restartEndpoint' in 'RestartEndpointWithIntegrationConfiguration' not loaded because @ConditionalOnClass did not find required class 'org.springframework.integration.monitor.IntegrationMBeanExporter'
    - Bean method 'restartEndpointWithoutIntegration' in 'RestartEndpointWithoutIntegrationConfiguration' not loaded because @ConditionalOnEnabledEndpoint no property management.endpoint.restart.enabled found so using endpoint default

Action:

Consider revisiting the entries above or defining a bean of type 'org.springframework.cloud.context.restart.RestartEndpoint' in your configuration.
如果我设置spring.cloud.kubernetes.reload.enabled为false一切正常，则会读取并使用configmap。现在我的目标是在configmap更改时重新加载配置，但是获得上面看到的异常。我可以/actuator/refresh手动调用，所以我不认为缺少刷新端点的可用性。
