Question

我使用properties{ minIdle = 5 maxIdle = 25 maxWait = 10000 timeBetweenEvictionRunsMillis = 5000 minEvictableIdleTimeMillis = 60000 validationQuery = "SELECT 1" validationQueryTimeout = 3 testOnBorrow = true testWhileIdle = true testOnReturn = false defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED }获取spring-boot-starter-actuator端点。

现在我还想使用localhost/metrics和dropwizard.metrics依赖项。在他们的网页（https://dropwizard.github.io/metrics/3.1.0/getting-started/）上声明，metrics-servlets带有某种指标管理菜单，会创建健康，线程转储和ping。

但我没有看到那个servlet。我是否可能必须在spring-boot中明确注册？

Answer 1

我必须显式地实例化servlet并提供servlet映射路径，如下所示：

@Bean
public ServletRegistrationBean servletRegistrationBean(){
    return new ServletRegistrationBean(new AdminServlet(),"/metrics/admin/*");
}

Answer 2

如果有人正在使用5.0.0版，则必须执行以下步骤才能使其正常工作：

@Inject
private ServletContext servletContext;

@Inject
private MetricRegistry metricRegistry;

@Inject
private HealthCheckRegistry healthCheckRegistry;

@Bean
public ServletRegistrationBean<Servlet> servletRegistrationBean(){
    servletContext.setAttribute(MetricsServlet.METRICS_REGISTRY,
        metricRegistry);
    servletContext.setAttribute(HealthCheckServlet.HEALTH_CHECK_REGISTRY,
        healthCheckRegistry);

    return new ServletRegistrationBean<>(new AdminServlet(), "/metrics/*");
}
