springboot + ApplicationListener

ApplicationListener自定义侦听器类

@Component
public class InstantiationTracingBeanPostProcessor implementsApplicationListener<ContextRefreshedEvent> {private static final Logger LOG = Logger.getLogger(InstantiationTracingBeanPostProcessor.class);private static boolean initialized;@Autowiredprivate ManageResolver manageResolver;@Overridepublic void onApplicationEvent(ContextRefreshedEvent event) {try {//只在初始化“根上下文”的时候执行final ApplicationContext app = event.getApplicationContext();if (null == app.getParent()&& ("Root WebApplicationContext".equals(app.getDisplayName())|| app.getDisplayName().contains("AnnotationConfigEmbeddedWebApplicationContext"))&& "/xweb".equals(app.getApplicationName())) { // 当存在父子容器时，此判断很有用LOG.info("*************:" + event.getSource());LOG.info("*************:" + app.getDisplayName());LOG.info("*************:" + app.getApplicationName());LOG.info("*************:" + app.getBeanDefinitionCount());LOG.info("*************:" + app.getEnvironment());LOG.info("*************:" + app.getParent());LOG.info("*************:" + app.getParentBeanFactory());LOG.info("*************:" + app.getId());LOG.info("*************:" + app.toString());LOG.info("*************:" + app);if(!initialized && !manageResolver.IsInitialCompleted()) {manageResolver.initLater();initialized = true;}}} catch (Exception e) {LOG.error("((XmlWebApplicationContext) event.getSource()).getDisplayName() 执行失败，请检查Spring版本是否支持");}}}
