ApplicationListener自定义侦听器类
@Component public class InstantiationTracingBeanPostProcessor implements ApplicationListener<ContextRefreshedEvent> { private static final Logger LOG = Logger.getLogger(InstantiationTracingBeanPostProcessor.class); private static boolean initialized; @Autowired private ManageResolver manageResolver; @Override public 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"); } } }
