This is the method that started the Eureka program in the class as a whole, but where?

  1. EurekaServerInitializerConfiguration SmartLifecycle is realized
  2. Where SmartLifecycle extends Lifecycle, Phased

Overridden and returns true

public void start() { new Thread(new Runnable() { @Override public void run() { try { //TODO: is this class even needed now? eurekaServerBootstrap.contextInitialized(EurekaServerInitializerConfiguration.this.servletContext); log.info("Started Eureka Server"); / / release register event publish (new EurekaRegistryAvailableEvent (getEurekaServerConfig ())); EurekaServerInitializerConfiguration.this.running = true; Publish (new EurekaServerStartedEvent(getEurekaServerConfig())); } catch (Exception ex) { // Help! log.error("Could not initialize Eureka servlet context", ex); } } }).start(); }Copy the code

The eurekaServerBootstrap contextInitialized related code

Public void contextInitialized(ServletContext context) {try {// Initialize the Eureka runtime environment initEurekaEnvironment(); // Initialize the eureka context initEurekaServerContext(); / / this is a configuration item can ignore the reading context. The setAttribute (EurekaServerContext. Class.
