Question

在支持Java8的应用程序上从SpringBoot1迁移到SpringBoot2之后，启动时我遇到了运行缓慢的问题。

启动需要35-40分钟，在一个名为'tomcatPoolDataSourceMetadataProvider'的单个bean上大约需要15分钟。

07/08/2019 15：46：05.382调试 org.springframework.beans.factory.support.DefaultListableBeanFactory： [main] [{}]-通过bean名称按类型自动装配 'org.springframework.boot.actuate.autoconfigure.metrics.jdbc.DataSourcePoolMetricsAutoConfiguration $ DataSourcePoolMetadataMetricsConfiguration' 通过构造函数到名为“ tomcatPoolDataSourceMetadataProvider”的bean 07/08/2019 16：00：03.649调试 org.springframework.beans.factory.support.DefaultListableBeanFactory： [main] [{}]-创建单例bean的共享实例 'org.springframework.boot.actuate.autoconfigure.metrics.jdbc.DataSourcePoolMetricsAutoConfiguration'

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ImportResource;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.web.servlet.DispatcherServlet;


@SpringBootApplication(exclude = {DataSourcePoolMetricsAutoConfiguration.class})
@ImportResource(locations = {"classpath:spring-config.xml"})
@EnableCaching(proxyTargetClass = true)
@EnableScheduling
@EnablePoke
@EnableMetrics
@EnableApplicationMetrics
public class Application {

  @Value("${http.port}")
  private int httpPort;

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

  @Bean
  public ServletRegistrationBean servletRegistrationBean(DispatcherServlet dispatcherServlet) {
    ServletRegistrationBean register = new ServletRegistrationBean(dispatcherServlet);
    register.addUrlMappings("/*", "/ping");  // Allow root level ping.
    return register;
  }}

由于``tomcatPoolDataSourceMetadataProvider''，Spring Boot 2应用程序启动缓慢
