Performance Prometheus - not found

Question

I have a spring boot application and I am using vertx. I want to control services and jvm, and for this I chose Prometheus.

This is my MonitoringConfig class:

@Configuration
public class MonitoringConfig {

    @Bean
    SpringBootMetricsCollector springBootMetricsCollector(Collection<PublicMetrics> publicMetrics) {

        SpringBootMetricsCollector springBootMetricsCollector = new SpringBootMetricsCollector(publicMetrics);
        springBootMetricsCollector.register();

        return springBootMetricsCollector;
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean() {
        DefaultExports.initialize();
        return new ServletRegistrationBean(new MetricsServlet(), "/prometheus");
    }

}

And these are my dependencies:

<dependency>
            <groupId>com.moelholm</groupId>
            <artifactId>prometheus-spring-boot-starter</artifactId>
            <version>1.0.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/io.prometheus/simpleclient -->

        </dependency>

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

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

        <dependency>
            <groupId>org.springframework.hateoas</groupId>
            <artifactId>spring-hateoas</artifactId>
        </dependency>

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

It does not show errors in the application, but when I try to access http: // localhost: 8787 / prometheus , I get Not Found.

Also, I tried only with the drive, and it is still the same.

http: // localhost: 8787 / actuator , http: // localhost: 8787 / health , etc. Allways receipt: not found.

So my question is what can cause this and how can I fix this problem?

vert.x , .

jvm :

new DropwizardExports(SharedMetricRegistries.getOrCreate("vertx")).register();
