I have application with spring mvc annotation configuration. In my local environment(IDE) it is working perfectly. When i deployed in prod(tomcat 8.5) my application listener calling multiple times. Because of this my executor tasks, schedulers calling multiple times.
AppWebAppInitializer.java
package com.app.config;
public class AppWebAppInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(AppMvcConfig.class);
servletContext.addListener(new ContextLoaderListener(ctx));
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("appServlet",new DispatcherServlet(ctx));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");
dispatcher.setAsyncSupported(true);
servletContext.setSessionTrackingModes(EnumSet.of(SessionTrackingMode.COOKIE)); //uses cookies instead of jsessionId in the url.
}
}
AppMvcConfig.java
package com.app.config;
@Configuration
@EnableWebMvc
@EnableScheduling
@EnableCaching
@ComponentScan("com.app")
@Import({
AppPropertyInitConfig.class,
AppSecurityConfig.class,
WebSocketConfig.class
})
public class AppMvcConfig extends WebMvcConfigurerAdapter implements ApplicationContextAware{
private ApplicationContext applicationContext;
@Value("${app.upload.dir}")
private String uploadDir;
public void setApplicationContext(ApplicationContext applicationContext) {
this.applicationContext = applicationContext;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
ApplicationStartupListener.java
package com.app.listener;
@Component
public class ApplicationStartupListener {
private final Logger logger = LoggerFactory.getLogger(ApplicationStartupListener.class);
@Autowired
private LookupHolder lookupHolder;
@EventListener
public void handleContextRefreshEvent(ContextRefreshedEvent event) {
logger.info("ApplicationStartupListener initializing lookups");
Runnable lookupInitRunnable = () -> lookupHolder.init(); //initialize the lookups
new Thread(lookupInitRunnable).start();
}
}
In above code ApplicationStartupListener.java --> handleContextRefreshEvent() calling multiple times. As well as my spring default schedules also calling multiple times
In my application i don't have web.xml
