Spring Boot Application Started Event For post-initialization, we can implement InitializingBean interface and provide implementation of afterPropertiesSet() method. At what point is brevity no longer a virtue? This will run at startup of the Spring container.

Spring Applicationlistener Example

When defining a bean that you create with a static factory method, you use the class attribute to specify the class containing the static factory method and an attribute named factory-method How do I accomplish this? Spring Application Startup Listener At this point the Spring Beans are loaded, configured and ready for use.

Your example code would with our beans which are multi-thread safe. If you need to use an autowired bean or value for a bean to be correctly configured, place the configuration code in an @PostConstruct-annotated method. –Paul Dec 3 '15 at 18:11 Spring Application Context Load On Startup

Below is my application class. In my web.xml, I have contextConfigLocation /WEB-INF/application.xml And in application.xml I have Do I add a bean here? Then we could work on further optimizing the beans with longest init times, to whittle the time down further. http://arnoldtechweb.com/on-startup/wpf-run-on-startup.html I have a event fired property, which I initialize to false.

Though the content you are publishing is very good and with in depth analysis. Every at least mid-experienced j2ee developer will warn you against it. All users already logged on continue to use the old version, until they logoff. Spring Boot Postconstruct It can be handy for doing cleanup work, like closing connections.

The easiest approach, I guess, is to create an ApplicationListener which listens to ContextRefreshedEvents. (This is fired when the context is up) and which starts initializing the caches, you could plugin You still invoke the bean the 'spring way' (eg: through the spring AoP proxy).

We can do this either by defining bean of type org.springframework.context.annotation.CommonAnnotationBeanPostProcessor or by context:annotation-config element in spring bean configuration file.Let's write a simple Spring application to showcase the use of above As I mentioned, there is another project at the company that already does something similar and they got their startup time to be very short ~ 1-2 min. Web applications are inherently multi-threaded and the threads are exclusively managed by the web container.
