Have you started the application using spring-boot or dropper the war in tomcat? This issue occurs when launching like this: |
|
Yes. There is an ActivityService defined as @managedservice( |
|
I'm also getting the handshake error when dropping the war directly in tomcat |

There is serious issue here :-) Websocket is not available at all DEBUG] pro.tremblay.myapp.aop.logging.LoggingAspect - Exit: pro.tremblay.myapp.repository.CustomAuditEventRepository.auditEventRepository() with result = pro.tremblay.myapp.repository.CustomAuditEventRepository$1@236b4a44

I don't know how Spring Boot works, but normally the first class executed should be |
|
Spring Boot is seems to be broken: spring-projects/spring-boot#1722 |
|
Use private void initAtmosphereServlet(ServletContext servletContext) {
log.error("Registering Atmosphere Servlet");
AtmosphereServlet servlet = new AtmosphereServlet();
Field frameworkField = ReflectionUtils.findField(AtmosphereServlet.class, "framework");
ReflectionUtils.makeAccessible(frameworkField);
NoAnalyticsAtmosphereFramework atmosphereFramework = new NoAnalyticsAtmosphereFramework();
ReflectionUtils.setField(frameworkField, servlet, atmosphereFramework);
ServletRegistration.Dynamic atmosphereServlet =
servletContext.addServlet("atmosphereServlet", servlet);
servletContext.setAttribute("AtmosphereServlet", atmosphereFramework);
atmosphereServlet.setInitParameter("org.atmosphere.cpr.packages", "pro.tremblay.myapp.web.websocket");
atmosphereServlet.setInitParameter("org.atmosphere.cpr.asyncSupport", Servlet30CometSupport.class.getName());
servletContext.addListener(new org.atmosphere.cpr.SessionSupport());
atmosphereServlet.addMapping("/websocket/*");
atmosphereServlet.setLoadOnStartup(3);
atmosphereServlet.setAsyncSupported(true);
}but there are serious issue with SpringBoot + WebSocket. |
|
Ok. But I don't seem to have any @serverendpoint. How is the AtmosphereInitializer supposed to by called? |
|
AtmosphereInitializer is supposed to be called by the server itself. e.g any application deployed in a J2EE Container will be initialized when a META-INF/services is defined. This is Servlet Spec basic. Unclear to me why Spring Boot breaks that. |
|
Wow. That's much better. Now I'm getting some live results. Thanks! spring-boot seems to require to emulate some J2EE behavior manually. There is a SpringBootServletInitializer. So the AtmosphereInitializer should probably be called somewhere around there. |
|
However, I'm getting a bunch of [WARN] org.atmosphere.util.IOUtils - |
|
Hum. The SpringBootServletInitializer isn't called either. They must be called only when deployed on a server. I think initAtmosphereServlet is supposed to replace the AtmosphereInitializer but doesn't work very well. At least I should be able to work now. Thanks! |
|
Hum... The world is not saved yet. After a while, it freezes the browser and I'm getting these: WARN] org.atmosphere.config.managed.ManagedAtmosphereHandler - AtmosphereRequest{ method=POST contextPath= servletPath=/websocket pathInfo=/activity requestURI=/websocket/activity requestURL=http://localhost:8080/websocket/activity AtmosphereResource UUID=33540705-9766-44ae-b31d-4874776b91d3 destroyable=true} received an empty body But it kinda looks like the tracker is tracking the websocket themselves or something weird like that. |
the issue. I've deployed on Tomcat 8.0.15 and everything seems to starts properly. What is the next steps?
