Spring boot: Start an application automatically when Webshere Application Server starts? -

assume have springboot application deployed war websphere application server (was). war contains daemon, must start straight away when starts (and once).

however, still need activate springboot servlet doing http request.

now understand concept of servlets act on http requests, still want auto started on appserver start. makes daemon portable standalone jar/main war/webapp.

i tried servletcontextlistener, contextinitalized called @ first http request.

i not have web.xml (servlet 3).

code:

@springbootapplication @weblistener public class demoapplication extends springbootservletinitializer implements servletcontextlistener {      @override     public void onstartup(servletcontext servletcontext) throws servletexception {         system.err.println("onstartup");          super.onstartup(servletcontext);     }      public static void main(string[] args) {         springapplication.run(demoapplication.class, args);     }      @override    protected springapplicationbuilder configure(springapplicationbuilder application) {       return application.sources(demoapplication.class);    }       @override     public void contextinitialized(servletcontextevent sce) {         system.err.println("contextinitialized");      }      @override     public void contextdestroyed(servletcontextevent arg0) {         //     } } 

and:

@component public class demorunner implements applicationrunner {      @override     public void run(applicationarguments arg0) throws exception {         system.err.println("i running");     }  } 

when start first this:

launching defaultserver (websphere application server 16.0.0.2/wlp-1.0.13.cl160220160526-2258) on java hotspot(tm) 64-bit server vm, version 1.7.0_79-b15 (en_us)  [...]   [audit   ] cwwkt0016i: web application available (default_host): http://localhost:9080/demo/  [audit   ] cwwkz0001i: application test started in 17,282 seconds. 

to spring boot application starting, first need visit link (http:/localhost:9080/demo/). starts rolling, starting startup method can see in log. how can starting without doing http request?

you can change loadonstartup customize spring dispatch servlet, here sample question , can use code

@bean public static beanfactorypostprocessor beanfactorypostprocessor() {     return new beanfactorypostprocessor() {          @override         public void postprocessbeanfactory(                 configurablelistablebeanfactory beanfactory) throws beansexception {             beandefinition bean = beanfactory.getbeandefinition(                     dispatcherservletautoconfiguration.default_dispatcher_servlet_registration_bean_name);              bean.getpropertyvalues().add("loadonstartup", 1);         }     }; } 

reference: how configure 'dispatcherservlet' load on startup spring boot?

upate

seems there more simple way, can config in application.properites

spring.mvc.servlet.load-on-startup=1
